4->'''Amy''': It's beautiful here, but there's a loneliness here. The land feels sad and empty.\
5'''Sonic''': Yeah, I got the same feeling. And I think it's tied to the ruins, weird robots, and other stuff we've encountered. But on the plus side, I've got plenty of room to run around.

7''Sonic Frontiers'' is a 3D ''Franchise/SonicTheHedgehog'' title released on November 8, 2022 for the Platform/PlayStation4, Platform/PlayStation5, Platform/NintendoSwitch, Platform/XboxOne, Platform/XboxSeriesXAndS, and PC via {{Platform/Steam}} and Platform/EpicGamesStore.
8
9Sonic, Tails and Amy are en route to the Starfall Islands in search of the Chaos Emeralds, which wound up there as a side effect of Dr. Eggman's latest plot to conquer the world: stealing the secrets of the [[{{Precursors}} Ancients]], an impossibly advanced civilization that once populated the islands. Suddenly, a wormhole sucks the trio in and scatters them across Cyber Space, a digital realm from which only Sonic manages to escape. Now on his own, Sonic receives three instructions from a voice in the sky: find the Chaos Emeralds, destroy [[HumongousMecha colossal machines]] known as the Titans, and tear down the walls between dimensions. It's now up to Sonic to free his friends and decipher the mysteries surrounding these new frontiers, all while facing Eggman's newest helper: a girl named Sage, who does everything in her power -- including controlling the Titans -- to make the hedgehog leave.
10
11In the process of exploring the islands, Sonic begins to discover the history of the Ancients, and in doing so may learn many secrets deeply kept for so long -- including why the Ancients vanished, and even the true origin of the Chaos Emeralds themselves...
12
13Described by Creator/SonicTeam head Takashi Iizuka and game director Morio Kishimoto as the template for a "third generation" of ''Sonic'' titles, ''Frontiers'' brings the franchise into the CollectAThonPlatformer genre, taking the blue blur across sprawling, "open-zone" landscapes, and giving him new combat techniques to battle the strange robotic adversaries scattered across the Starfall Islands. Sonic also attains a new ability known as the Cyloop, allowing him to create a closed trail of light with a variety of uses in both combat and puzzle-solving. The goal of each island is to find all seven Chaos Emeralds, upon which Sonic will be able to become Super Sonic and take the fight to the island's Titan. To do this, Sonic will need to collect Memory Tokens and use them to bring his friends back from Cyber Space, which will lead him to some Emeralds as well as snippets of the Ancients' history. Each island also has more traditional stages taking place in Cyber Space, and completion of each stage will grant Sonic Vault Keys needed to release some of the Emeralds stuck inside Vaults. Inhabiting the Starfall Islands are the Koco, little stone-like creatures that Sonic can rescue to collect rewards to improve his base stats.
14
15Notably, this is the first ''Sonic'' game to have Creator/IanFlynn, who is most known for writing the [[ComicBook/SonicTheHedgehogArchieComics Archie]] and [[ComicBook/SonicTheHedgehogIDW IDW]] comics, as its English scriptwriter.
16
17A prequel webcomic titled ''Sonic Frontiers Prologue: Convergence'', focused around Sonic, Amy, Tails, and Eggman, was released in two parts in October 2022, with the [[https://twitter.com/sonic_hedgehog/status/1582370960354660352 first part]] released on October 18th and [[https://twitter.com/sonic_hedgehog/status/1584911709021798401 second part]] on October 25th. A prequel animated short film starring Knuckles, titled ''[[https://www.youtube.com/watch?v=_gjszHTDjzo Sonic Frontiers Prologue: Divergence]]'' released on November 1st, 2022.
18
19On November 30th, 2022, new free updates were announced to release throughout 2023.
20
21* The first update, titled "'''Sights, Sound and Speed'''" (released March 22nd), adds a [[SoundTest jukebox]] that lets you listen to classic ''Sonic'' music in the open zones, a PhotoMode, and timed BossRush and Cyber Space challenges.
22* The second update, titled "'''Sonic's Birthday Bash'''" (released June 23rd), adds aesthetic changes to celebrate Sonic's birthday, new Action Chain challenges on each island (and a new move as a reward for S-Ranking all of them, that being the ever-classic Spin Dash), special platforming puzzles that have costume-wearing Koco at the end, and the ability to access NewGamePlus.
23* The third update, titled "'''The Final Horizon'''" (released September 28th), adds new playable characters (Tails, Knuckles, and Amy) and a new story that overhauls the game's climax. A further update to "'''The Final Horizon'''" would release on December 6th, which included a variety of bug fixes and addressed major complaints about the new story.

52!Warning! A number of {{First Episode Twist}}s occur before getting even half-way through the first island. As such, several early spoilers [[NeverTrustATrailer hidden by the trailers]] will be unmarked, and it's recommended to at least complete the first island before reading this page.

56!!''Sonic Frontiers contains examples of:''
57[[folder:# - C]]
58* EleventhHourSuperpower: In "The Final Horizon" update, Sonic goes on a quest to complete the trials of [[spoiler:the pilots of the Titans and the Master King, creator of the Titans, in order to convert his cyber-corruption into a new power. However, the true extent of the power can [[ItOnlyWorksOnce only be used once]] [[DangerousForbiddenTechnique due to how much power it uses]]. In the new final boss, Super Sonic utilizes this power against THE END who uses SUPREME as a vessel and is able to used the Perfect Parry to dodge ''any'' attack. When THE END is on its last legs, Sonic used his full power, turning into a cyber-corrupted version of Super Sonic, and is fired out of SUPREME's rifle by Eggman, a combination powerful enough to destroy both SUPREME and THE END [[OneHitKill in one shot]].]]
59* HundredPercentCompletion:
60** If you manage to 100% map all islands, watch all side stories and get Sonic's stats completely maxed out, you get to fight the TrueFinalBoss, "Vandalize" is replaced by "One Way Dream" during the credits, and [[spoiler:an [[TheStinger extra scene]] is added to the ending that addresses Sage's fate]] in the base game. Though all of this can also be accessed if you finish the game on Hard difficulty, even if you just swap the difficulty to Hard right before fighting the final boss.
61** After the "Sonic's Birthday Bash" update, 100% completion now includes defeating every Guardian, collecting every Memory Token and special Koco, finding all of the Side Stories, finding and S-Ranking all of the Cyber Space portals, finding the fishing portals, and finally S-Ranking the Action Chain Challenges on every island. [[AndYourRewardIsClothes All of this nets you the "Frontiers Elite" outfit, which gives Sonic a golden crown to wear]].
62* AbsurdlyHighLevelCap: Your maximum ring capacity, speed, attack, and defense are capped at 99 each. You can comfortably beat the FinalBoss with none of them being higher than 50. ''The Final Horizon'', on the other hand, ups the difficulty such that even maxing out your stats will still offer a significant challenge; in fact, you practically need to get your levels extremely high just to be able to damage the Guardians beyond ScratchDamage.
63* AbsurdlyLowLevelCap: On the flipside, Extreme difficulty locks Sonic's stats to Level 1. This, combined with that difficulty's OneHitPointWonder nature drastically changes the way you approach the game.
64* AchievementsInIgnorance: When Sonic first encounters Big, he asks how he got here, with "here" being Cyber Space's various fishing locations. Big's answer? He was looking for fishing spots and ended up there. Everyone else had to be dimensionally warped in.
65* AfterTheEnd: As Sonic explores the Starfall Islands, he gradually learns it exists in the aftermath of something that devastated it and its people. Specifically, it used to be inhabited by [[spoiler:an alien race of people known as the Ancients, who first owned the Chaos Emeralds. However, they were helpless against THE END, who destroyed their civilization, but not before they sealed it away, along with the souls and technology into Cyber Space to prevent THE END from doing any further damage.]]
66* AllThereInTheManual:
67** The highway Cyber Space theme is called "Eternal Highway", according to a Japan-only guidebook.
68** [[spoiler:The two new transformations for Super Sonic in ''The Final Horizon'' go unnamed (with the first only being referred to as "Super Sonic's hidden power") in-game, but in the game's files, the blue-eyed Super Sonic is named "Super Sonic 2" and the fully cyber-corrupted Super Sonic is named "Super Sonic Cyber."]]
69* AmericanKirbyIsHardcore: Inverted. The [[https://pbs.twimg.com/media/Fa424DcXgAIXBhc?format=png&name=small Japanese/Asian box art]] has Sonic running off with a serious look on his face. Meanwhile, the [[https://pbs.twimg.com/media/Fa3igtpUIAALkMh?format=jpg&name=medium International box art]] has him smiling while grinding on a rail.
70* AnachronismStew: PlayedForLaughs when Sonic discovers what's clearly a ''pinball game'' set up in ''ancient ruins'', with lights, bumpers, flippers, music and all. He leaves the game wondering if the concept of pinball is just a constant throughout history no matter what. The game also makes a story point for why much of the Ancients' technology is so advanced. The Final Horizon update adds a conversation about ''why'' it was a pinball machine, with Tails laughing it off by saying that the engineers were likely having some fun with it.
71* AndYourRewardIsClothes: As of the "Sonic's Birthday Bash" update, getting OneHundredPercentCompletion in every island will unlock the "Frontiers Elite" costume, which gives Sonic a golden crown.
72* AntiFrustrationFeatures:
73** The game's auto-save can't be overwritten or deleted, and autosaves every few minutes. Additionally, the final autosave trigger is shortly prior to the final boss trigger, so after finishing the game, the whole game can still be accessed.
74** To emphasize the open-world nature of the game, the developers design it so that a player can choose how to engage with elements of the game at their leisure. For example, while Vault Keys, which are necessary to get the Chaos Emeralds, are typically obtained from completing Cyber Space stages, you can also find Vault Keys in the world, through combat, or by collecting enough Fishing Coins to buy one at Big's shop.
75** If you happen to die by falling off the islands into the water, you respawn around the last bit of solid ground you were previously on, letting you continue on your way without having to backtrack. Similarly, dying against a Guardian in the field just brings you back to a little bit outside of its engagement range, letting you have the choice of either fighting it again or moving away to try again later.
76** Rather than needing to use Rings to build up Boost energy, the Boost just recharges at a fairly quick rate by itself if not actively used. It's very handy for those times where you can't easily get Rings.
77** The game has an "Auto Mode" that simplifies the combat system for players who are more interested in the exploration and platforming. Combat in general is largely optional and is not required to complete the game.
78** The player can choose between two control styles: Action Style allows more accurate platforming and is designed for newcomers to the series, while High Speed Style gives Sonic more speed and is designed for veteran and hardcore players.
79** The player can change the difficulty at any time with no drawback, for example if the player found the game easier or harder than what they where expecting. [[spoiler:It's also useful for accessing the TrueFinalBoss without having to play through the whole game again.]]
80** The player can customize Sonic's acceleration, turning sensitivity, and terrain resistance among other stats through sliders in the Settings menu, a feature which was not previously seen in a 3-D ''Sonic'' title.
81** The number of Memory Tokens, Seeds of Power/Defense, and Portal Gears in the world is not finite; they can all drop from regular enemies, and those enemies respawn with every Starfall. Should you lack any of these resources and find the current challenges too difficult/time-consuming, turning the island into a MookHorrorShow is a viable tactic. If that's still too much work, then you can also buy them with coins earned from fishing or grilling.
82** Speaking of fishing, Portal Gears, Vault Keys, and Memory Tokens will display as "Sold Out" at Big's shop once you've obtained as many as you'll need to do everything on the current island to keep you from wasting your money. The same is true for Power and Defense seeds once you have enough to get the respective stat to 99.
83** Fishing requires purple coins that are scattered on the overworld or awarded by the roulette on the occasional Starfall. It is possible to run out between Starfalls, but even if you do, it is still possible to earn Big's tokens for free, by grilling.
84** Fishing works on a set sequence of things that Sonic will catch rather than random chance, so completing each area's catch collection is guaranteed after a set number of fishing attempts.
85** When engaging a Titan as Super Sonic with less than 100 rings, for example because the Titan smacked them out of you, you'll be topped off to that amount upon starting the battle. This also applies to the preview of the Titan on Chaos Island as regular Sonic.
86** The game doesn't call as much attention to it as other features of the map, but the player can warp to any previously visited island at any point to clear up any objectives they missed before. The button to do so is stated at the bottom left of the screen.
87** Each Cyber Space stage's objectives don't have to be completed all at once, so you could finish a few of them before completing the remaining missions. Any Red Star Rings you collected will be saved so you don't have to collect them all in one go.
88** Failing the pinball minigame at the end of Chaos Island enough times will first add an extra life, then add return springs to the outlanes to eliminate the likelihood of a random unlucky drain killing the multiplier.
89** When climbing up the towers on [[spoiler:Rhea Island]], certain spots will release pulleys acting like checkpoints, soaring the player from anger should they fall all the way down.
90** The westernmost Island Mystery on Ouranos Island is a bit of a GuideDangIt in both how it functions, and how it is accessed. The way it works is that [[spoiler:it can be triggered at any time by interacting with the pedestal the same way one would interact with a Portal. It functions exclusively on audio clues, unlike the rest of the game, and works by Cylooping the three tuning forks in the matching order (at any point, not necessarily consecutively) — middle, left, right]]. Cyber Space Portal 4-7 and one location of the Hermit Koco are "locked" behind it. However, the game provides three other ways of reaching them. The gate can actually be bypassed by simple platforming, and doing so puts you next to a trigger button that will unlock platforms to provide a return path. Because the section of the map contains both a Cyber Space Portal and an Elder Koco, the area behind the gate can be accessed by fast travel two different ways, either by warping to the Hermit Koco by obtaining a scroll from fishing and clearing the closest Challenge, or by clearing all challenges and warping to the portal.
91** During the BulletHell fight with [[spoiler:the TrueFinalBoss]], your starting lives will actually start going up every couple rounds if you die enough to give you more breathing room.
92** The first free update adds some quality-of-life improvements: the Starfall Slot Machine can now be toggled off (for players who find it distracting during gameplay), and the Elder Koco will now upgrade your stats in bulk (originally, you had to upgrade them one at a time).
93** The second free update allows players to change Sonic's deceleration when he stops moving and when he jumps, allowing him to conserve his momentum. It also gives a toggle for disabling the cinematic camera for certain Skills and to remove the music filter when boosting in Cyber Space.
94** As part of said update, switching the difficulty to Easy on Rhea Island will provide balloons and other gimmicks to help with traversing the towers.
95** Like with Rhea Island, playing on Easy will add springs and balloons to the Towers of the Masters in the third free update. Additionally, it increases the length of time for the Perfect Parry.
96** Fail the trials often enough, and the game will offer to lower their difficulty.
97* ArcWelding: The game also provides an origin story for the Chaos Emeralds as well as the Chao and Chaos.
98* ArtEvolution: In contrast to the more cartoony and stylized art direction present in the last few games, this title shows off a more grounded and realistic aesthetic in similar vein to the ''[[VideoGame/SonicAdventure Adventure]]'' [[VideoGame/SonicAdventure2 titles]], ''VideoGame/SonicTheHedgehog2006'', and ''VideoGame/SonicUnleashed''. However, the Cyber Space levels are as cartoony and stylized as previous games, in part because they are {{Nostalgia Level}}s, and also because two of the three themes [[CutAndPasteEnvironments reuse]] [[NostalgiaLevel their]] [[NewWorkRecycledGraphics assets]] from ''[[VideoGame/SonicGenerations Generations]]'' and ''[[VideoGame/SonicForces Forces]]'', which were in turn renditions of [[VideoGame/SonicTheHedgehog2 Chemical Plant Zone]] and [[VideoGame/Sonic3AndKnuckles Sky Sanctuary Zone]].
99* ArtisticLicenseBiology: The "alligator" from the fishing minigame is more evidently a crocodile, as shown by its pointed snout, interlocking teeth, and lighter coloring.
100* ArtisticLicenseMarineBiology: Some of the fishes Sonic can pull out while fishing, such as hammerhead sharks, are not primarily found in lakes. Though this can probably be excused by the fishing spots being in Cyber Space and also carrying [[MythologyGag Chopper badniks, Goal Posts, and Item Monitors]], among other things; it's a collection of memories based on Sage and Sonic's conversation in the Final Horizon update.
101* AscendedGlitch: The third episode of ''Speed Strats'' explains and gives an official name to the Homing Dash, a dash move performed by canceling a Homing Attack with a Boost, which is generally understood to be an unintentional quirk of the physics engine. [[WordOfGod Morio Kishimoto]] [[https://twitter.com/moq_46/status/1619142578695454720?t=2tWnEUuczEbF9diQ1ln1wA&s=19 revealed on Twitter]] that he knew about the Homing Dash during development, and while unintended, he kept it in as a technique in the hopes that players would enjoy it. The "Sights, Sounds, and Speed" update adds an in-game acknowledgement, in the form of an asterisk next to your clear time if you use it in a Cyber Space level.[[invoked]]
102* AscendedMeme: The third episode of ''Speed Strats'' referenced two of the game's memes: Surprise SQUID [[note]]a sudden jump cut to SQUID's BossSubtitles when it comes into range [[/note]] and Cyber Space Level 1-2 [[note]]infamous for being ThatOneLevel and a case of EarlyGameHell[[invoked]][[/note]].
103* AstralFinale: The final boss fight of the base game sees Super Sonic [[spoiler:teaming up with Sage to fight against THE END]] in space [[spoiler:before it can destroy the Earth]]. This is downplayed in the Final Horizon update's new final boss, [[spoiler:where THE END uses SUPREME as its new avatar]], fighting Sonic on the island instead of in space until [[spoiler:Sonic obliterates THE END in a cutscene at the end.]]
104* AutobotsRockOut: Every time Sonic has collected all the Chaos Emeralds and is going up against the Titan of the current island, the fight is accompanied by a heavy metal song by Kellin Quinn, with each boss having its own song.
105* BagOfSpilling:
106** A rare case where this happens multiple times in the same game. Although Sonic has to collect all seven Chaos Emeralds to defeat the Titan on each island and move on to the next, he's always shot down between islands, causing him to lose the Emeralds and forcing him to start the process from scratch.
107** In a broader sense, Sonic is still missing the ability to drift ever since ''Forces'', though on the flip side he seems to be able to use the Drop Dash from ''Mania''. He also seems to be missing his MercyInvincibility.
108* BettingMiniGame: On the night that a meteor shower occurs, collecting fallen pieces will bring up a slot machine for a chance to earn more purple fishing coins.
109* BigBad: [[TheHeavy Sage]], Dr. Eggman's latest creation who has captured Sonic's friends and is now using the Titans to try and kill the hedgehog, [[spoiler:[[RedHerring isn't actually the true threat]]. In reality, her actions are all part of an attempt to stop a powerful and manipulative entity known as [[EldritchAbomination THE END]] from escaping the islands and destroying the universe.]]
110* BigDamnHeroes: During the [[spoiler:Final Battle in The Final Horizon update, SUPREME/THE END launches a powerful attack against Eggman when he picks SUPREME's gun - Sage then creates a Cyber Barrier to protect her father, however, it starts to break under the mutated Titan’s onslaught. When she resigns herself to die while shielding Eggman, Amy, Knuckles and Tails reach her in their cyber forms and reinforces the barrier to protect Eggman while Super Sonic battles SUPREME/THE END.]]
111* BittersweetEnding: The ending of the game features Sonic winning, but does so with a few saddening caveats: [[spoiler:Sonic and Sage team up to defeat THE END, saving the universe from the threat and avenging the Ancients. However, Sage sacrifices herself to do so, and Sonic and his friends end up disbanding -- for the time being, anyway. TheStinger after the GoldenEnding lightens it to being more sweet than bitter, though, when Eggman manages to save Sage and upload her into his computer. The "Final Horizon" ending makes this a bit sweeter in that Sage survives due to the alternate plan Sonic and Eggman formulate, and the shot of Eggman looking at the meteor shower caused by THE END's defeat is revised to now include Sage as the two decide to go home as a family.]]
112* BlindIdiotTranslation: The Japanese script, surprisingly, has several issues not present in the original English script. Continuity is inconsistent (character motivations change on the fly, Sonic introduces himself to Sage after she's already learned his name), the tone of the dialogue often doesn't match the body language of the animation, Eggman's CharacterDevelopment regarding Sage is [[DubPersonalityChange almost entirely excised from the main story]], and even basic characterization is occasionally fumbled (for example, Sonic calls Amy [[UsefulNotes/JapanesePronouns "kimi"]] instead of "omae" as he usually does, with no explanation as to why). The result is something several Japanese fans have called equivalent to a machine translation; not incomprehensible, but clearly unpolished.
113* {{Bookends}}:
114** The intro cutscene has Eggman upload a device into the red ancient technology spires with all the gravitas he usually has when putting into his schemes. [[spoiler:TheStinger of the base game sees Eggman working diligently and calmly working on one of his computers with a blue layout to restore Sage.]]
115** The first Titan, GIGANTO, ragdolls Sonic into the side of a mountain with a toss, knocking him out in a single attack. [[spoiler:Sonic's fatal blow on [[BigBad THE END]] in the base game's final battle is Sage using the SUPREME Titan, which looks much like GIGANTO, committing a FastballSpecial of the same hand tossing him to pierce the creature through]].
116** The climax acts as one for the franchise as a whole. The series began in the first game with Sonic and Eggman feuding over the Chaos Emeralds. ''Frontiers'' ends with Sonic and Eggman [[spoiler:[[EnemyMine teaming up]] to collect the Chaos Emeralds and destroy [[GreaterScopeVillain the very being]] that caused them to be brought to Earth in the first place]].
117* BossInMookClothing: The Wolf enemy functions more like a Guardian and unlike other mooks. It is triggered by proximity, and once triggered is inescapable and causes a perspective change. It is fought by consecutively parrying every Wolf that attacks you while the others encircle you, and then when all are parried, the player can either flee, or defeat them all before the remaining ones encircle the player again. If the player misses too many parries, the circle shrinks until it eventually instantly kills Sonic. It is also the only basic enemy in the game to have its own encounter music, like the Guardians.
118* BossRush: The Sights, Sounds, and Speed update added the "Battle Rush" mode as an unlockable once the game is completed. It takes the Boss Rush concept up a few notches by having Sonic fight all [[MiniBoss Guardians]] ''and'' normal enemy types on a chosen island in addition to the Titan of that island, all in as short a time as possible. Plus, there's an option to marathon all of the islands when each of them has been individually defeated.
119** [[spoiler:To achieve the powered-up Super Sonic form in the "Final Horizon" update, you need to run through GIGANTO, WYVERN and KNIGHT once more as part of Master King Koco's trials. The battles aren't straight rematches though as each of them limit Sonic's stats into a fixed pool, require perfect parry timing to defend against enemy attacks and prevent Super Sonic from regaining any rings.]]
120* {{Bowdlerise}}: The ending theme of ''Sonic Frontiers'', "Vandalize" by Music/OneOKRock, off their ''Luxury Disease'' album, has the lyrics "Fuck the pain away, my bed is in ruins" and "Oh, you're fucking crazy" changed to "Fight the pain away, my head is in ruins" and "Oh, you're freaking crazy", respectively for the version for the game. Other innuendos in the lyrics are re-contextualized to fit with the events of ''Frontiers''.
121* BrickJoke: When Sonic escapes Cyber Space and hears a mysterious voice call him "the key", he remarks "Sure beats being called a [[VideoGame/SonicAndTheSecretRings 'rodent']]". [[spoiler:When Eggman gloats over Sonic being left comatose and trapped between dimensions due to cyber-energy corruption, guess what Eggman calls him?]]
122* BulletHell: The [[spoiler:full fight with THE END (only seen in the base game when fought in Hard Mode)]] takes the form of an UnexpectedShmupLevel, and given [[VideoGame/{{Ikaruga}} its inspiration]], it hands black and white bullets out like candy. Good thing you've got that polarity mechanic...
123* BulletTime: If Sonic dodges an enemy right before it attacks him, he can briefly slow down time for a couple of seconds, allowing him to get some extra hits in.
124* BraggingRightsReward:
125** Extreme difficulty can only be unlocked by getting S-Ranks on all Battle Rush stages. Beating the game on Extreme doesn't earn you anything so it's mostly there as proof of your skills.
126** Getting S-Ranks on all Cyber Space Challenges lets Sonic use the Power Boost in Cyber Space stages. This doesn't mean much since you already proved you can steamroll through those stages without it. [[BonusFeatureFailure It can't even be used in Arcade Mode either]]. Thankfully, the "Sonic's Birthday Bash" Update upgrades this to {{Justified|Trope}} status, thanks to the addition of NewGamePlus.
127** The Sonic's Birthday Bash update adds the Spin Dash as an unlockable skill to Sonic's arsenal, but it can only be obtained after S-Ranking all Action Chain challenges. {{Downplayed|Trope}} as it's still incredibly useful for general traversal, can be used in all game modes, and can be carried over to NewGamePlus.
128* BreakingOldTrends:
129** This game ditches the linear stage-to-stage progression that has been a staple of the franchise since the very first game in favor of an open world sandbox for its primary gameplay. That said, traditional ''Sonic'' levels are still present in the form of the Cyber Space stages.
130** This game breaks the 3D ''Sonic'' trend of only having the final boss be fought by Super Sonic, as now there are multiple bosses that only Super Sonic can fight, those being the Titans.
131** Despite originally being planned to release for the ''Sonic'' series' 30th anniversary, there's almost no sign of Classic Sonic[[note]]The sole exception is from a brief flashback to ''VideoGame/SonicTheHedgehog3AndKnuckles''[[/note]], who was a fixture of the [[VideoGame/SonicGenerations last]] [[VideoGame/SonicForces two]] anniversary games.
132** In addition, this is the first anniversary title to not involve the majority of the recurring ''Sonic'' cast in the story. With it instead involving the five primary characters, as well as Big the Cat ([[TheBusCameBack who wasn't in previous anniversary games]]), with the rest of the cast being brand new to the series.
133** The Wisps, which were featured in some way in every 3D game since their debut in ''Colors'', are a no show in this game. Sonic's incidental dialogue on [[spoiler:Rhea]] Island can mention Yacker.
134** For the first time in a mainline title since ''VideoGame/SonicUnleashed'', [[spoiler:Dr. Eggman is not the FinalBoss of the game -- in fact, Eggman is TheUnfought]].
135* BreakingTheFellowship: ''Frontiers'' ends with [[spoiler:the temporary disbandment of Team Sonic's current incarnation, with Tails, Knuckles, and Amy all choosing to pursue their individual adventures knowing that they would have to pursue them without Sonic for the time being]].
136* BrutalBonusLevel: The "Another Story" side campaign introduced in the third update, filled with all new towers to climb, challenges being offered, and remixed Cyberspace stages that will absolutely push you and your knowledge of the game to its definite limits.
137* TheBusCameBack:
138** Big the Cat makes his first appearance in a mainline ''Sonic'' game since ''VideoGame/SonicHeroes'', after 19 years of being relegated to spin-offs and cameos. [[spoiler:Though according to Sage in a conversation with Sonic in the Final Horizon update, this isn't actually Big, but rather a reconstruction of him from Sonic's own memories]].
139** The Cyclone from ''VideoGame/SonicAdventure2'' makes its first re-appearance within the games (outside of a brief cutscene from ''VideoGame/ShadowTheHedgehog'') as part of Tails' moveset in "The Final Horizon" update.
140* CallBack:
141** In the [[https://twitter.com/sonic_hedgehog/status/1582370960354660352 tie-in comic]], Sonic, Tails, and Amy take on a robot piloted by Eggman. During the battle, he spouts out [[MemeAcknowledgement some familiar lines]] from ''VideoGame/SonicAdventure'' and ''VideoGame/SonicGenerations'' specifically.
142--->'''Sonic:''' Hold up...I've heard all this mad ranting before...
143** ''Prologue: Divergence'' contains many references to ''VideoGame/SonicAdventure'', including a flashback to the day the Echidna civilization disappeared. Knuckles' monologue is similar to his speech at the beginning and end of his story in ''Adventure'', musing on why he was given the responsibility to protect the Master Emerald. The scenes with Chao also contain allusions to the Chao Garden, such as Knuckles punching a tree to drop fruit and headpatting a Chao to calm it down.
144** Several references to past games can be found in Eggman's Egg Memos that Big will exchange for tokens in his fishing game.
145*** Eggman muses how the ancients that left relics across the islands must predate [[VideoGame/Sonic3AndKnuckles the]] [[VideoGame/SonicAdventure echidnas]], [[VideoGame/ShadowTheHedgehog the Black Arms]] and [[VideoGame/SonicRiders the Babylonians]].
146*** He notes how Cyber Space is influenced by the outside world, including the [[VideoGame/SonicAdventure2 United]] [[VideoGame/ShadowTheHedgehog Federation]] and [[VideoGame/TeamSonicRacing Planet Donpa]].
147*** He boasts about how he's made Eggman an AppropriatedAppellation, but refuses to do the same for [[VideoGame/SonicColors Baldy McNosehair]].
148*** He discusses how he never knew [[VideoGame/SonicAdventure2 his cousin Maria]], and wonders if [[spoiler:Sage's personality]] is similar to hers.
149*** He discovers that the Ancients are relatives of [[VideoGame/SonicAdventure Chaos]], even starting his memo by remarking [[VideoGame/SonicAdventure "I don't believe this!"]]. He also refers to Chaos as "the God of Destruction," which was one of his first lines from ''Sonic Adventure.''
150*** He notes he previously used Amy as a pawn [[VideoGame/SonicCD in]] [[VideoGame/SonicAdventure his]] [[VideoGame/SonicAdventure2 plans]], that Knuckles' anger and the Master Emerald have proven [[VideoGame/Sonic3AndKnuckles useful]] [[VideoGame/SonicAdventure in]] [[VideoGame/SonicAdventure2 the]] [[VideoGame/SonicAdvanceTrilogy past]], and that Tails had caused trouble for him in [[VideoGame/SonicAdventure Station Square]] and [[VideoGame/SonicAdventure2 the ARK]].
151** Late into the story, Sonic and Tails stumble upon [[spoiler:a destroyed [[VideoGame/SonicForces Assault-model Death Egg Robot]]]], which they use to clear the way forward.
152** Sonic references many past locations in his incidental voice lines (triggered by spending several minutes in the overworld without triggering a portal or Guardian fight). In particular, [[VideoGame/SonicTheHedgehog1 Green Hill]], [[VideoGame/Sonic3AndKnuckles Sandopolis, Lava Reef, Hidden Palace, Sky Sanctuary]], [[VideoGame/SonicAdventure Mystic Ruins, a Chao Garden, Red Mountain]], [[VideoGame/SonicAdventure2 Green Forest]], [[VideoGame/SonicHeroes Rail Canyon]], [[VideoGame/SonicRiders Babylon Garden]], [[VideoGame/SonicUnleashed Spagonia, and Shamar]] are all referenced, with Hidden Palace being the only one among them that is not directly name-dropped.
153** Once again, [[spoiler:[[VideoGame/SonicAdventure2 a Hedgehog in a Super form plummets to Earth from orbit after exhausting himself saving the world]]; luckily, it goes better for Sonic than [[VideoGame/SonicHeroes it did]] [[VideoGame/ShadowTheHedgehog for Shadow]].]]
154* CanonWelding: ''Frontiers'' name-drops {{Canon Foreigner}}s in such a way as to imply they have become {{Canon Immigrant}}s. (They had already appeared in past spin-offs, but ''Frontiers'' is the first core ''Sonic'' title to acknowledge them.)
155** Sonic mentions Tangle, among other characters, if he spends a lengthy amount of time (about 10 minutes) on the open world without fighting a Guardian or entering a portal. While exploring Kronos Island, Sonic casually muses, "I bet [[ComicBook/SonicTheHedgehogIDW Tangle]] would love climbing around these ruins." This is additionally notable in that Tangle wasn't even originally a game character.
156** At the end of the game, Amy wonders aloud if Cream and [[WesternAnimation/SonicBoom Sticks]] are available for a road trip.
157** Egg Memo 4 sees Eggman mention "Planet Donpa Kingdom race data", alluding to the planet and hosts of the racing spin-off ''VideoGame/TeamSonicRacing''.
158* {{Cap}}:
159** Without any upgrades to Sonic's Ring Capacity (meaning it's at Level 1), the maximum amount of rings he can carry is 400. Upgrades to Ring Capacity grant him around 6 extra rings per level. When the Ring Capacity is maxed out, Sonic can carry up to 999 rings.
160** All four stats max out at Level 99.
161** Big's shop will only let you buy around 200 Lost Koco per island (which amounts to 10 purchases since he sells them in packs of 20), with the exception of the final island, where he will let you keep buying them forever even after you have enough to max out both Speed and Ring Capacity.
162* CaptainsLog: The Egg Memos obtained by fishing and trading tokens with Big are audio logs created by Eggman, showing his perspective during the game's events.
163* CharacterCustomization: While it's not a core feature like in ''VideoGame/SonicForces'' and ''VideoGame/SonicColors: Ultimate'', and the option is only available via external DLC, the player can customize Sonic's appearance in the extras menu with a few pre-determined looks. These include:
164** The shoes from ''VideoGame/SonicAdventure2'' (obtained by subscribing to the ''Sonic Frontiers'' newsletter until January 31, 2023).
165** A pair of brown gloves and boots (which is obtained by getting the digital deluxe version).
166** [[WebAnimation/{{Hololive}} Inugami Korone]]-themed gloves and shoes (which is obtained by pre-ordering the Japanese version from Joshin web).
167** Two armor sets based on ''VideoGame/MonsterHunterRise'' (which are free DLC).
168** The "Holiday Cheer" outfit gives Sonic a costume based on SantaClaus (added as a free update on December 2022).
169* CharacterDevelopment:
170** Sonic is shown to be a bit more mature in this title. He's more empathic to his friends' needs and concerns and even doles out surprising bits of wisdom to help them with their problems.
171** A surprising amount is given to the returning non-Sonic leads. Tails comes to terms with his loss of confidence and reliance on Sonic, and intends to set off on his own to grow as his own person; Knuckles shares that he wishes he could be free like Sonic, and considers leaving Angel Island to go on his own adventures; and Amy decides to stop focusing her affections on Sonic and share her love with the world. Even Eggman gets some development, actively becoming a loving father to Sage.
172* ChainPain: During the battles with WYVERN and KNIGHT, if a player performs a Cyloop as Super Sonic, they will be bound by chains made of yellow energy, which temporarily restricts their movement.
173* CheatedAngle: Sonic's mouth is always on the side of the face most facing the player. If you look directly at the camera, turn the camera just a little bit left or right, and watch Sonic's mouth switch sides.
174* CheckpointStarvation: The Cyber Space stages and Master Trials exclusive to "The Final Horizon" lack checkpoints, so a single loss sends you back to the start, including [[spoiler:the Master Koco's Trial, which has you fight the first three Titans in a row with only 400 Rings]].
175* ClimaxBoss: In addition to several minor bosses scattered throughout the environment, each island has a major boss that Sonic must acquire all of the Chaos Emeralds to engage. Upon defeat, the Emeralds are scattered to the next island for Sonic to find again.
176* CollectAThonPlatformer: While taking heavy inspiration from modern open world games, the game is ultimately billed as "open zone", featuring explorable-yet-dense segmented areas as opposed to one cohesive world. In addition, there are many items to collect either to progress through the game or enhance Sonic's abilities.
177* ColourCodedForYourConvenience:
178** [[HumongousMecha The Guardians]] ASURA and CATEPILLAR emit red and blue gates or orbs. Blue gates are used to proceed with the fight, while red ones push him back or damage him, respectively.
179** The Portal Gears and Vault Keys have a different colour depending on which island you're on.
180*** Kronos Island: Cyan
181*** Ares Island: Yellow
182*** Chaos Island: Red
183** Memory Tokens match their associated character: Pink Hearts for Amy [[spoiler:and Sage]], Yellow Wrenches for Tails, and Red Medals for Knuckles.
184** In Cyber Space levels, coloured asterisks will appear next to your completion time if certain game-breaker techniques are used:
185*** Homing Dash: White
186*** Power Boost: Blue
187*** Altered Deceleration Rate: Yellow
188*** Spin Dash: Red
189* ColossusClimb:
190** Fighting an ASURA involves leading it to slam down a hand, climbing up the arm (or alternatively scaling its body directly if Sonic falls off but manages to reach its body before hitting the ground – Air Boost works quite well on that), then going AttackItsWeakPoint on the shoulder tower. You need to do this [[RuleOfThree three times]] to take an ASURA down, and climbing/attacking gets harder with each arm destroyed, as the remaining shoulder towers first get a rotating energy barrier for defense, and the final tower will be further defended by energy balls firing off to blast Sonic.
191** Every Titan [[spoiler:except SUPREME]] requires climbing up to the top of their heads to reach the final Chaos Emerald needed to become Super Sonic, all of which provide plenty of obstacles designed to knock you off and force you to restart the climb.
192* CompanyCrossReferences:
193** The Cyloop move is similar in name, appearance, and usage to the Paraloop from Sega's ''VideoGame/NightsIntoDreams'' series. The [=NiGHTS=] Chao from ''Sonic Adventure'' also appear in ''Prologue: Divergence''.
194** The language that the Ancients speak? It's very similar to [[VideoGame/PanzerDragoon Panzerese]], or the language of [[VideoGame/NightsIntoDreams Nightopians]]. The Titans they created are also HumongousMecha that boast physics-defying power and agility and are powered by their very souls, similarly to [[VideoGame/VirtualOn Virtuaroids]].
195** The music for the pinball minigame on Chaos Island was composed by veteran Sega composer Hiroshi Kawaguchi and features many hallmarks of his work on classic Sega arcade games, such as the drum kit and whistles heard in ''VideoGame/FantasyZone'', and a bassline remarkably similar to that of "Passing Breeze" from ''VideoGame/OutRun''.
196** When triggering the special boost in the open zones or making a successful catch in Big's fishing minigame, Sonic does an {{Eyedscreen}} heavily resembling those from ''VideoGame/Persona3'' and ''VideoGame/Persona4'', which also brings to mind [[https://youtu.be/DhAo2inLJeo Yu catching the River Guardian]] in ''Anime/Persona4TheAnimation''.
197* ConnectedAllAlong: What seems at first like RuinsForRuinsSake are gradually revealed to be [[spoiler:the work of the Ancients, who were the original wielders of the Chaos Emeralds and ancestors of [[VideoGame/SonicAdventure Chaos]], and whose works became the basis of Angel Island and the Echidna tribe]].
198* ContinueYourMissionDammit: If you idle or wander aimlessly for too long on Kronos Island without anything really happening, the voice guiding Sonic will take a minute to thoroughly explain how the game's progression works so that you get back on track. Similarly, trying to explore off the map (with the same happening on [[spoiler:Rhea Island]]) will make them chide you to get back on the path.
199* ContinuityCavalcade: Between Sonic's incidental dialogue, his interactions with his friends, and Eggman's Egg Memos, there are a ''lot'' of references to games across the series. And not just mainseries titles, but references to spin-offs like ''VideoGame/SonicRiders'' and the [[VideoGame/SonicStorybookSeries Storybook games]]. There's even CanonWelding references to characters from [[ComicBook/SonicTheHedgehogIDW the IDW comics]] and ''WesternAnimation/SonicBoom''.
200* ContinuityNod: This game is ''full'' of them, owing to Ian Flynn being a PromotedFanboy, as well as being planned to be released on the 30th anniversary. [[invoked]]
201** In ''Prologue: Divergence'', after Knuckles recounts the story of his ancestors' fate from ''VideoGame/SonicAdventure'', ripples spontaneously appear in a puddle, just like how Chaos manifested in the pool around the Master Emerald shrine. A glowing amber orb -- the Hint Orb, later revealed to be the spirit of Tikal -- also flies by. Sonic also mentions Tikal by name during the game when trying to make sense of what's happened to Amy, Knuckles and Tails.
202** After [[spoiler:Knuckles gets transported away from Angel Island to the Starfall Islands]] in ''Prologue: Divergence'', the first thing Knuckles does is yell out for Eggman, asking him if this is another of his "tricks."
203** When the AI voice declares Sonic to be "the key" in the game's opening cutscene, Sonic muses that it [[VideoGame/SonicAndTheSecretRings "sure beats being called a rodent"]].
204** After getting trapped in Cyber Space, Eggman mentions having built [[VideoGame/ShadowTheHedgehog similar]] [[VideoGame/SonicForces digital constructs]] in his own systems.
205** After defeating GIGANTO, Sonic (as Super Sonic) tells Amy he'll find a way to save her "faster than she can read a Fortune Card", alluding to her Tarot reading from her ''VideoGame/SonicCD'' backstory.
206** When Sonic & Knuckles [[spoiler:stumble upon some Ancient Koco ruins]] they ponder if they're related to Angel Island, and Knuckles has a flashback to his first meeting with Sonic & Tails from ''VideoGame/SonicTheHedgehog3''. The flashback is even lifted directly from the game itself in 16-bit.
207** Knuckles finds himself commanding some Koco soldiers, calling back to his role as TheLeader of the resistance in ''VideoGame/SonicForces''.
208** After Super Sonic defeats WYVERN, Knuckles jokes that he could have handled it if he was [[VideoGame/Sonic3AndKnuckles Super Knuckles]].[[note]]This is notable for being the first acknowledgement of Super Knuckles outside of the classic continuity, as Sega previously had a mandate that prevented anyone but male hedgehogs from having Super forms in the modern continuity.[[/note]]
209** After defeating the WYVERN, Super Sonic flinches when Knuckles throws his fist out to gesture at him, a potential reference to how Knuckles was able to depower Super Sonic with a single hit in their [[VideoGame/Sonic3AndKnuckles first encounter]].
210** Sage brings up some of Eggman's past [[EnemyMine collaborations with Sonic]] when explaining that [[spoiler:he might be the key to bringing him out of Cyber Space]], such as when they stopped [[VideoGame/SonicAdventure2 the ARK]] and [[VideoGame/SonicHeroes Neo Metal Sonic]]. Eggman angrily says that those were only temporary alliances.
211** Tails remembers that he "couldn't handle it [[VideoGame/SonicForces when Infinite attacked]]" and specifically mentions "one wrong turn and I fell apart," likely referencing the scene where he cried for Sonic's help when he was attacked by Infinite's illusion of Chaos. Sonic is noticeably concerned when it's mentioned, since he wasn't present when it originally happened. Later, Sonic gives Tails a pep talk by mentioning how [[VideoGame/SonicAdventure he saved Station Square]], [[VideoGame/SonicAdventure2 broke Sonic out of prison]], and [[VideoGame/SonicLostWorld rescued Sonic from the Deadly Six's trap]], with visual references to the original scenes like with Knuckles' previous flashback.
212** Upon uncovering an environmental analyzer, Sonic and Tails are shown a vision of the past in which [[spoiler:the Ancients fired beam cannons into the sky and were annihilated by an unseen force above]], with Tails comparing the destruction to what was caused by [[VideoGame/SonicUnleashed Dark Gaia]].
213** When Sonic and Tails discover [[spoiler:a beam cannon created by the Ancients, Sonic compares it to the [[VideoGame/SonicAdventure Egg Carrier]]. Tails says it must be even stronger, almost on par with the [[VideoGame/SonicAdventure2 Eclipse Cannon]]]]. This also doubles as {{foreshadowing}}, since [[spoiler:THE END takes the form of a large planetoid; the Eclipse Cannon was powerful enough to [[DetonationMoon destroy part of the moon]] on lower settings and at full power could destroy planets and pierce stars]].
214** In Big's fishing mini-game, some of the things Sonic can fish out are a Chopper badnik, a goal post, a red spring, and a star post checkpoint from the early ''Sonic'' games.
215** Sonic will reminiscence about the Mystic Ruins when he comes across the waterfall on Kronos Island. He will also sometimes think about Shamar while exploring Ares Island.
216** In shots of space, the Moon is only seen directly from the front rather than rotating like the Earth does, because [[VideoGame/SonicAdventure2 it was blown in half]].
217** When [[spoiler:THE END announces that it will escape from Cyber Space and destroy the world]], Eggman retorts that he'll mobilize [[VideoGame/SonicHeroes the Egg Fleet]] to attack it.
218** Sonic remarks that one Cyber Space level reminds him of [[VideoGame/SonicRiders Babylon]] [[VideoGame/SonicRidersZeroGravity Garden]], and mentions Jet the Hawk.
219** Sonic says he hopes Zavok is doing "terribly"; not surprising, considering [[VideoGame/SonicLostWorld their]] [[VideoGame/SonicForces previous]] [[VideoGame/TeamSonicRacing encounters]].
220** One of Sonic's ranged attacks is a beefed-up variant of his old Sonic Wind attack that first appeared in ''Adventure 2'', where he first brought it out as a counterpoint to Shadow's Chaos Spear attack.
221** When Eggman learns of Sage's plan to revive Sonic's friends in ''The Final Horizon'', he complains about the potential of hearing a soppy speech about the "super power of teamwork", referencing the famous line from ''Sonic Heroes''.
222** While exploring the island as Amy in Another Story, Knuckles quips how he doesn't want anyone like Rouge or the Babylon Rogues to steal the Chaos Emeralds first.
223* CosmicHorrorReveal: While there have been the occasional {{Eldritch Abomination}}s here and there, the games always leaned heavily on the lower scale of LovecraftLite. This game, however, brings in a sense of cosmic dread through a specific late-game character: [[spoiler:THE END, the true villain of the game, an incomprehensible horror from beyond the stars that destroys planets like it's nothing. Its true form [[NothingIsScarier can't even be seen]], and all the backstory segments of the Ancients show their entire planet being wiped out by rays of destruction raining down from the heavens, all without even seeing what it is that's killing them all. When THE END breaks free from its seal, it assumes the form of a sentient purple moon, which Sage reveals is not complete yet, and nearly destroys Earth with a [[WaveMotionGun gigantic laser]]. It takes the combined might of Super Sonic and Sage piloting the SUPREME Titan to try and stop it, but given its immortality, it's likely that won't stick. There's no backstory or any reason for why it does what it does either, only that it is inevitable, and that it can't truly be stopped]].
224* CounterAttack: The Grand Slam skill (the first story-locked skill unlocked by freeing Amy) allows this by, after parrying an incoming attack, giving Sonic a prompt to counter with an unblockable high-damage attack. The counterattack animation depends on the enemy being countered. Recovery Smash is a more conventional version that triggers when Sonic gets hit and works the same way.
225** Open-world enemies and Guardians get spin-dashed into the air before being sent flying away with a Homing Attack.
226** GIGANTO gets spin-dashed in the face and kicked into the ground by multiple Super Sonic speed clones.
227** WYVERN gets its tail grabbed by Super Sonic and [[GrievousHarmWithABody swung around before Sonic chucks it into a mountain]].
228** KNIGHT has Super Sonic use his speed to trip up KNIGHT then spin dash it into the air before sending it back down with an axe kick.
229** SUPREME is the only one that doesn't get a counter, as it sends Super Sonic away with its drones before he can get the chance.
230*** [[spoiler:In The Final Horizon update, SUPREME/THE END attacks Super Sonic head-on, however the superpowered hedgehog uses a Lightspeed attack to throw it away.]]
231* CoupDeGraceCutscene: All of the major Titan bosses feature one of these, some containing {{Action Command}}s, and others being a cinematic that plays once Sonic depletes the boss' HP bar:
232** After GIGANTO's HP has been reduced to 0 and Sonic attacks its head while it's staggered, Super Sonic plunges through its stomach, coming out the other side, where GIGANTO then explodes after impact.
233** After WYVERN's HP is reduced to a certain amount, the boss will then [[DeathFromAbove charge towards Sonic from above]], with the player required to pull off a few [[PressXToNotDie QTE sequences]] to survive and stop its impact. Following that, WYVERN will fire several missiles at Sonic, where after succeeding the timed press, he will fly around and redirect the projectiles towards the Titan. The final QTE of the scene requires Sonic to forcibly open its jaw, where [[ThrowDownTheBomblet the missiles fly down its mouth]] and destroy the Titan from the inside. If the player misses any of these [=QTEs=], then it's an instant kill.
234** The KNIGHT also has two back-to-back, with the first scene triggering when Sonic locks-on and attacks the head of the Titan. Sonic must first [[BladeCatch stop the KNIGHT's blade with his hands]], where he's then thrown into a mountain while holding the sword. After managing to hold off the sword, he kicks it away, facing it down in a non-interactive cinematic. He dodges the sword, then punches the Titan sky high, which causes the sword to fly into the nearby volcano. Sonic then proceeds to use his Cyloop to ''lift the sword'' and then bisect the KNIGHT with his own weapon, [[DiagonalCut splitting it in two]] and finishing it off. Failing any of these [=QTEs=] will also instantly kill Sonic.
235** The base game's final boss, [[spoiler:and fourth Titan, SUPREME, doesn't have one, where the boss simply falls over after being defeated by Super Sonic. However, Sonic and Sage then fly into space to fight THE END, where either the final QTE sequence will play immediately (on Normal or lower difficulties) or after you battle it in the space shooter segment for the TrueFinalBoss. Regardless, Sonic will first hold off a beam of light that is fired at him, until Sage helps defend against it. Once the laser is shaken off, [[FastballSpecial Sage throws the hedgehog into the moon like a baseball]] using SUPREME, where Sonic has to succeed three [=QTEs=], which will penetrate THE END's moon form. However, [[TakingYouWithMe it then tries to destroy itself along with Sage and Sonic]], forcing the AI to sacrifice itself in order to end the battle]].
236** The final boss of the Final Horizon update, [[spoiler:THE END possessing SUPREME, first has Super Sonic kicking the Titan straight into the air, before following it up with several [[RapidFireFisticuffs punches and kicks that they look like streaks of light]], which carry THE END higher and higher. Sonic then cinches it with one last timed [=QTE=] punch, sending it soaring and immobile in the air. Another cinematic then plays after that, where Eggman commands Sonic to get into the SUPREME's rifle, with Sonic acting as the bullet. Sonic then proceeds to unleash all of the power he was holding back with the Cyber Corruption, transforming into Super Sonic Cyber. Eggman then powers up the cannon, aims, and fires Sonic right at the prone SUPREME, which Sonic destroys in a single hit, followed by THE END's moon form shortly afterwards]].
237* CoverVersion: [[spoiler:The theme for the FinalBoss of ''The Final Horizon'' is a metal remix of "I'm Here" with [[Music/SleepingWithSirens Kellin Quinn]] performing, bringing it in line with the other Titan themes.]]
238* CreepyDoll: It can be applied to [[spoiler:SUPREME/THE END, since the Titan is nothing more than a zombified puppet of the EldritchAbomination]].
239* {{Crossover}}:
240** The Japanese console versions of the game contain [[https://twitter.com/SonicOfficialJP/status/1562289865441816578 three collaboration DLC packs]] with {{WebAnimation/Hololive}}'s VirtualYouTuber [[Characters/HololiveJapanGAMERS Inugami Korone]] (who is an official ''Sonic'' ambassador in Japan): a SillinessSwitch that changes the sound effects to Korone sounds, a toggle to change the Kocos into Koronesuki, and [[https://twitter.com/SonicOfficialJP/status/1562290372101173248 special cosmetic shoes and gloves]] inspired by her standard outfit.
241** With ''Sonic''-themed cosmetics having made various appearances in Creator/{{Capcom}}'s ''VideoGame/MonsterHunter'' series, a free post-launch DLC pack for ''Frontiers'' returns the favor, featuring two different sets of Rathalos armor, based respectively on the hunters' set and the Palicoes' set, as well as a meat cooking mini-game. Both sides also produced promo art to celebrate the team-up ([[https://twitter.com/sonic_hedgehog/status/1579624098485108737 SEGA]], [[https://twitter.com/monsterhunter/status/1579624301820772352 Capcom]]).
242* CosmeticAward: Subscribing to the official newsletter unlocks Sonic's Soap shoes from ''VideoGame/SonicAdventure2''.
243* CurbStompBattle: In his first encounter with a Titan, Sonic gets easily trounced and tossed away. He's forced to collect the Chaos Emeralds and trigger his Super form in order to stand a chance against all four Titans.
244* CutAndPasteEnvironments: There's only four distinct themes for Cyber Space levels, three of which are ripped straight out of ''Sonic Generations'': Green Hill Zone, Chemical Plant Zone, Sky Sanctuary Zone, and a fourth "city" theme that is mostly original but has thematic inspiration from games such as ''Sonic Adventure'' and ''Sonic Adventure 2''.
245* CutsceneIncompetence: Despite Super Sonic having the explicit power to parry lasers and {{Wave Motion Gun}}s during {{Boss Battle}}s, the plot on multiple occasions has Super Sonic being shot out of the sky by laser cannons, which forces him to lose the Chaos Emeralds and [[HereWeGoAgain collect them again]].
246* CyberNinja: The NINJA enemies and their variants, while not looking much like their namesakes, are one of the few humanoid robots in the game, they wield blades and perform ninja techniques, such as NinjaRun and DoppelgangerAttack.
247* {{Cyberspace}}: On his adventure, Sonic will access portals to Cyber Space in order to collect the keys necessary to get the Chaos Emeralds. Cyber Space takes the form of traditional ''Sonic'' settings such as Green Hill, with level design and gameplay akin to ''VideoGame/SonicUnleashed'', ''VideoGame/SonicColors'', ''VideoGame/SonicGenerations'', and ''VideoGame/SonicForces''.
248[[/folder]]
249
250[[folder:D - L]]
251* DamnYouMuscleMemory: The game throws a major curveball if you come into it thinking the controls are the same as in previous games.
252** Just like in ''VideoGame/SonicUnleashed'', the Homing Attack is done by hitting the attack/left face button[[note]]X on the Xbox controller, Square on the [=PlayStation=] [=DualShock=]/[=DualSense=] controller and Y on the Nintendo Switch controller[[/note]] as opposed to hitting the jump button again after jumping. Hitting jump again does a DoubleJump instead.
253** The boost -- which has always been activated by the left face button in previous games -- is now done by holding the right trigger button, which is guaranteed to trip up players who are used to how the boost functioned in previous games. The left face button is instead used as the attack button.
254*** The boost is also no longer capable of hurting enemies, not even in the Power Boost state. Enemies in the Open Zone lack CollisionDamage for this to be a problem, but Cyber Space is based on stages from ''Adventure 2'' (which had the Spin Dash), ''Unleashed'', and ''Generations'', where you were expected to plow through enemies. While enemy placements have been adjusted to reflect this change, you'll likely find yourself running head-first into a Motobug or Air Boost into a Buzz Bomber and lose all your rings in the process.
255** The light-speed dash is now activated by pressing the left analog stick, which is a massive contrast to how it was done in previous games, which had it be activated by one of the face buttons.
256** The Drop Dash returns, but can now only be done after a Double Jump instead of a regular Jump, meaning it essentially requires three button presses instead of two.
257** "The Final Horizon" update adds Amy, Knuckles, and Tails as playable characters for the final island in the game, and they have their key differences from Sonic that can give players a hard time:
258*** For starters, they need to unlock their Attack, Stomps, Parry, and Power Boosts, instead of them being part of their base kit, which makes combat, platforming, and travelling difficult and slower. They also do not have access to the Drop Dash, Light-Speed Dash, or Air Tricks.
259*** Amy and Tails cannot climb the green walls. Knuckles is the only character who can climb red ''and'' green walls, as Sonic cannot do the former.
260*** Tails cannot Homing Attack at all. Instead, he has a long-ranged wrench attack. His Cyloop special ability is also the only long-ranged one in the game.
261*** Amy and Knuckles' Homing Attacks have a slight delay when used (though not when in a Homing Attack chain).
262*** Their parries are also timed, unlike Sonic's (though in certain segments in Another Story, his parry also becomes timed).
263*** In comparison to previous games where they were playable, Knuckles and Tails' flight mechanics also work differently: namely, they both have a delay before they begin gliding/flying. Knuckles' glide in particular handles much more stiffly than in ''Adventure 2'' or '''06''. The 1.40 update altered Knuckles' gliding to be closer to how it was in ''Adventure 2'' and removes the initial delay.
264* DangerousForbiddenTechnique: [[spoiler:The Cyber power introduced in ''Another Story''. After receiving the blessings of the four Titan pilots and completing Master King's trial, Sonic is able to harness and utilize the energy of Cyber Space to give himself a power boost; however, Master King warns Sonic that the power is so strong he needs to temper it or else he'll spend it all and burn himself out. Though he keeps it under control and uses it to augment the power of the Chaos Emeralds as Super Sonic 2 during most of the final battle, he's forced to go all out and unleash its full energy as Super Sonic Cyber to destroy both SUPREME and THE END, unleashing its energy in a furious blast against the two and leaving him drained and unconscious after.]]
265* DarkerAndEdgier: The enemies are some of the creepiest in the series, the tone is significantly darker than even ''[[VideoGame/SonicForces Forces]]'' with the open zone music being more passive rather than bombastic, and a regular story element of the game is [[spoiler:watching the last days of the Ancients through the Kocos reliving their final moments, and who are explicitly DeaderThanDead and were killed off to the point of the cast strongly averting NeverSayDie repeatedly]]. It's to the point that the BigBad is [[spoiler:an EldritchAbomination that ''destroys and consumes entire planets and civilizations'']].
266* DeathIsASlapOnTheWrist: Falling off the islands or dying to an enemy or Guardian just rewinds time to a few moments beforehand, and you’ll usually have the rings you had beforehand intact. The worst that can happen is losing rings during a Cyber Space level or during a Titan fight (which sets your rings down to 100 in the latter case).
267* DeathOfPersonality: It can be applied to [[spoiler:SUPREME, after he is taken over by THE END and converted in a puppet during the Final Horizon update -- even the Boss Title Card changes its name to make it clear that SUPREME, as an individual entity, doesn't exist anymore]].
268* {{Determinator}}: Given a DeconReconSwitch. Not even unstoppable titans will prevent Sonic from saving his friends, but he starts to question his motive when Sage antagonizes him because of his reckless insistence of exploring the Starfall Islands, not knowing what dangers the ruins hold. He keeps going even after [[spoiler:the very act of saving his friends begins to corrupt him, eventually trapping him in Cyber Space]]. Sonic's determination in turn causes Sage to waver, making her question if the odds are really impossible. [[spoiler:It's Sonic's heroic spirit that ultimately convinces Sage to fight THE END along with him, following his lead in protecting his loved ones by sacrificing herself to keep Eggman safe]].
269* {{Deuteragonist}}: Each island follows the character arc of one of Sonic's friends; Amy for Kronos Island, Knuckles for Ares Island, Tails for Chaos Island, and [[spoiler:Sage for Ouranos Island]].
270* DevelopersForesight: One that specifically exists in the Nintendo Switch timed demo version of the game. Using SequenceBreaking tactics to reach GIGANTO early will cause the game to crash when attempting to turn Super Sonic, [[MundaneSolution simply because the developers removed Super Sonic's necessary files and everything after before uploading the demo]].
271* DiscOneFinalBoss: GIGANTO is built up as a major boss who needs the seven Chaos Emeralds in order to defeat. You indeed fight GIGANTO as Super Sonic, and a vocal theme even plays like in many prior 3D Sonic games' final bosses, but this is only the boss of the first island.
272* DoesThisRemindYouOfAnything: Sonic's [[spoiler:slow corruption from Cyber Space's energy, as he tries to save his friends]], is eerily similar to [[spoiler:a terminal illness that slowly consumes a person's body and eats away their lifespan. Even when he ultimately succumbs from the corruption, and has his mind "trapped between realities", it's treated more closely like an equivalent of death]].
273* DramaPreservingHandicap: While flying from Kronos to Ares, and later Ares to Chaos Island, Sonic is shot out of his super form by a laser to keep him from progressing too quickly.
274* DubPersonalityChange: Eggman's relationship with Sage is portrayed in a very different light in the Japanese dub than it is in the original English version. In English, Eggman develops a fondness for Sage over the course of the game, going as far as to consider her to be a daughter by the game's finale, while in Japanese, Eggman is portrayed as being rude and indifferent to Sage for much of the game, with his later development being almost entirely absent from the Japanese dub. That said, the Egg Memos show it's not a ''major'' change, where Eggman is still depicted as growing attached to Sage. He even makes the remark "Like parent, like child" when describing her. Eggman does care for Sage in the Japanese dub, but it's far more subdued, and mostly limited to the optional voice logs instead of obvious in the main story.
275* DumpStat: Ring Capacity is by far Sonic's least useful stat. Let us count the ways:
276** The stat determines the maximum amount of Rings Sonic can carry. You level up Ring Capacity by giving Kocos to the Elder Koco, but it's either that or increasing Sonic's Speed, which [[CaptainObvious might be more useful]] in a ''Sonic'' game (thankfully, you can swap levels between the two stats for free).
277** Sonic begins the game with a maximum cap of ''400'' Rings, enemies will shave no more than 20 - 60 Rings per hit, and each level of Ring Capacity increases the cap by a piddling 6 Rings.
278** The stat is only good for players who struggle with the Titan boss battles, which essentially use Super Sonic losing one ring a second as a soft time limit, but you'll always start the bosses with at least 100 Rings[[note]]If you enter the boss with less than 100 Rings, [[AntiFrustrationFeatures the game will top you off]][[/note]].
279*** It should be noted this is especially helpful in "The Final Horizon" update, where every time the final boss, [[spoiler:SUPREME/THE END]] hits you with a specific, commonly used attack, it [[MaximumHPReduction reduces Sonic's ring capacity by 30, reducing his ring count by the deficit if it would place his cap below his current ring count.]]
280** Finally, increasing your Ring cap is actually a ''hinderance'' if you want the Power Boost, which requires having max Rings.
281*** This is at least mitigated if you take the time to max out Speed first. The reward for reaching level 99 in Speed is that the Power Boost becomes permanent, regardless of how many rings Sonic holds.
282* DungeonBypass: The Memory Tokens strewn about each of the islands each require you to complete a short platforming challenge to get to them. Or at least, that's the idea. Due to the open-world nature of the game, it's quite possible to skip right to the end of a large number of them and skip all that hassle. Or you could skip gathering them entirely by spending a little while fishing and buying all the Memory Tokens you need with the coins earned from that. For that matter, you can also buy Vault Keys, meaning you can skip the actual levels as well.
283* EarnYourHappyEnding: ''The Final Horizon'' update puts the heroes through even more hardship than the base game. Along with the challenges being far more difficult and complex than in the base game, all the way up to [[spoiler:the new final boss SUPREME/THE END, Amy, Knuckles and Tails also start to suffer from the same painful cyber corruption that Sonic had. The new ending, along with it being a GoldenEnding for the player, is also much happier and more triumphant for the cast, as all of them join Sonic to take the boss down and prove their worth. Sage also survives through the end this time and joins Eggman to watch the closing starfall, then goes home with him as a family.]]
284* EmptyRoomPsych: Much of [[spoiler:Rhea Island's]] geometry is clearly designed for a fully-explorable world of its own, including climbable towers, wall-running segments, and ruins that naturally lend to platforming. However, it is immediately obvious that no items, objects, or enemies exist outside of the specific path that leads you to [[spoiler:the six towers (with the sole exception of a ramp on a difficult-to-access DisconnectedSideArea, implemented to [[DevelopersForesight prevent the player from getting trapped if they somehow made it there]])]], meaning there's nothing to actually ''do'' on the island. The "Sights, Sound, and Speed" Update alleviates this a bit by having Sound Memories around the island to collect, even in places off the beaten path.
285* EnemyMine:
286** Sage, citing Eggman and Sonic's [[VideoGame/SonicAdventure2 past]] [[VideoGame/SonicHeroes truces]], proposes another to get Eggman out of Cyber Space safely, but he flatly rejects that notion and tells her to find another way. [[spoiler:Later, when THE END is unleashed, Sage pleads with Eggman to help Sonic so that they can defeat the monstrosity. This time, Eggman agrees (albeit reluctantly) and is ultimately the one who recovers the final Chaos Emerald.]]
287--->[[spoiler:'''Eggman:''' Sonic, I hereby induct you into the Eggman Empire and order you to save us all. Understand? This is NOT an alliance!\
288'''Sonic:''' [[DeadpanSnarker If that's how you wanna spin it, Dr. Ego-man.]]]]
289** Expanded in the Final Horizon update, [[spoiler:since not only do Sonic, Eggman and Sage join forces to defeat THE END, but Amy, Tails, and Knuckles join the group as well, with Sonic and Sage going through many trials in Ouranos Island while the rest of Team Sonic plus Eggman recover the Chaos Emeralds. In the FinalBattle, all of them have important roles, which is determinant to finish SUPREME/THE END.]]
290* EnergyBall: Homing Shot, which is one of Sonic's many unlockable attacks that can be achieved by using Skill Points from the Skill Tree, allows him to launch up to 10 glowing blue spheres of energy and fire them as projectiles towards enemies.
291* EvenEvilHasLovedOnes: Eggman considers Sage to be one of his greatest creations to date in terms of Artificial Intelligence. At first, he sees her as [[JustAMachine just a computer program]], and in one Egg Memo, he even scoffs when he catches himself calling her "she" before correcting himself to "[[ItIsDehumanizing it]]". Then in the ''very next sentence'' he admits that she's extremely adorable and ''deliberately'' uses "she". By the next Egg Memo, he's proudly boasting about his wonderful daughter and how any idiot can make a kid the traditional way, but only a real genius like him can make one out of code.
292* EvenEvilHasStandards: Out of sheer pettiness, Eggman initially shoots down Sage's suggestion of [[EnemyMine working with Sonic]]. [[spoiler:When [[EldritchAbomination THE]] [[OmnicidalManiac END]] is free, the doctor relents and does work with the hedgehog. Even if Eggman doesn't like him, stopping the end of the world takes priority over any grudges he has with Sonic.]]
293* EvilAllAlong: PlayedWith. It's revealed that [[spoiler:the "spooky voice" guiding Sonic throughout the game is actually THE END, an EldritchAbomination trying to [[OmnicidalManiac destroy the universe]]]]. However, Sonic is [[ExcellentJudgeOfCharacter blatantly suspicious]] of it from the beginning, noting [[spoiler:[[ExactWords how vague its instructions are]] and [[ObviouslyEvil how creepy its voice is]]]], and he only follows its suggestions because [[MortonsFork he has no other options and Sage refuses to cooperate]].
294* ExactWords: The strange voice greeting Sonic tells him to defeat the Titans to help break through dimensions. Sonic believes that this is key to rescuing his friends from Cyber Space. While that is the case near the end, the voice never promised that, nor does it reveal why the dimensions should be broken.
295* ExplosiveOverclocking: One of the Cyber Space stages introduced in "The Final Horizon" revolves around a "Rev Gauge" where Sonic's speed increases while boosting uninterrupted, changing gears after enough time. The Spin Dash circumvents this entirely, letting Sonic go into top speed instantly. If you Spin Dash for too long, however, Sonic will burn out and explode, killing your momentum instantly.
296* FastAsLightning: As a possible inspiration from the live-action film series, Sonic gains a number of electrical attributes in this game, including his Boost gaining an electrical aura at full ring capacity and a full Stomp combo ending with emitting electrical sparks.
297* FastballSpecial: At the very end of [[spoiler:the game, Sage]] grabs Super Sonic and chucks him at [[spoiler:THE END]], giving him enough momentum to pierce through its body and deal a near-fatal blow.
298* FemBot: The NINJA-type enemies are an example of this, due to their [[ImpossibleHourglassFigure feminine]] [[HartmanHips proportions]] and [[SupermodelStrut animations]], made explicit with the KUNOICHI variant, whose name translates to "female ninja".
299* FirstEpisodeTwist: It's revealed during the first island that Sage is Eggman's DragonInChief, and shortly thereafter that she is his [[ArtificialFamilyMember artificial daughter]]. Her apparent Ancient digital corruption is because she built her avatar and physical form in Cyber Space and then exited it, rather than her being Ancient technology.
300* FishingForSole: Subverted in that the junk items Sonic can fish up such as a tire, a tin can, or a twig are considered high-quality catches and award ''more'' tokens than most fish. He ''is'' getting the tokens by trading the catches to notorious oddball Big the Cat, after all.
301* FishingMinigame: By collecting Purple Coins and then finding a special portal on each island, Sonic can access a fishing minigame hosted by Big the Cat. Each fish (and other random junk) that he collects earns him tokens which can be exchanged for items, including scrolls that allow for fast travel to certain points on that island, and audio logs left by Dr. Eggman that provide lore for the game's setting. Aside from its costs (which can be bypassed by the grilling minigame, the game is also completely '''overpowered''' in its rewards, as it is possible to completely max out Sonic's stats, and unlock all vaults, portals, and side story events, just by going fishing.
302* FlashStep: The "Phantom Rush" ability allows Sonic to lay the smackdown on his foes by delivering a rapid-fire succession of punches and kicks at such blazing speeds that he almost appears to be teleporting around his target.
303* {{Foil}}: Sage ultimately plays one to Sonic, as both are essentially {{Determinator}}s who will do anything to protect those they care about. In Sage's case, her motivation is to free Eggman from Cyber Space and prevent [[spoiler:the secrets of Starfall Island from endangering the world]].
304* {{Foreshadowing}}:
305** The reveal that [[spoiler:the Kocos are the ancestors of the Chao]] are subtly hinted at in the short, with Knuckles [[spoiler:helping a Chao retrieve some kind of Koco-related item]], and [[spoiler:the presence of a portal to the Starfall islands on Sky Sanctuary]].
306** Upon arriving on Rhea Island, the voice that's been guiding Sonic tells him he has one last task: to deactivate the towers there. Sonic quips, "Oh, good, I thought you were going to tell me there was a secret fourth Titan". [[spoiler:There is -- and it's being possessed by THE END, to whom the voice belongs.]]
307** On each island, the purple Chaos Emerald is always the last one Sonic acquires before going Super. [[spoiler:Guess what color [[TrueFinalBoss THE END]] is?]]
308* FourIsDeath:
309** Downplayed with [[spoiler:the fourth island, where Sonic finally succumbs to his cyber-corruption. While it's handled like a death, Tails describes it as him being "trapped between dimensions" in a comatose state]]. Either way, [[spoiler:[[SubvertedTrope he gets better]]]].
310** Zigzagged with [[spoiler:the fourth Titan, SUPREME. It's the only one ''not'' to be destroyed when Super Sonic defeats it, allowing Sage to pilot it against THE END in the base game's final battle. She then pulls a HeroicSacrifice while piloting it, meaning it gets destroyed anyway, but TheStinger in the GoldenEnding reveals Sage survived in some fashion]].
311*** Played straight in the Final Horizon Update. [[spoiler:SUPREME gets defeated the same way in the base game, even remaining intact after the battle. This however allows THE END to take control of it using a tether, causing it act more beast-like. Once Super Sonic manages to defeat it, he sends it flying straight into THE END's moonlike face. Dr. Eggman then charges up SUPREME's rifle, with Super Sonic Cyber acting as a bullet to destroy both the fourth Titan and THE END once and for all]].
312* GameMod: Notably, because this game made with the ''Hedgehog Engine 2'' - the core engine that has been used to develop the games since ''Sonic Unleashed'', in its current second iteration that debuted with ''Sonic Forces'' - the quite active hacking and modding communities for the franchise dove into its files and coding ''almost immediately'' upon release. This resulted in a ''much faster'' development of mods than with prior games, some of which introduced features like the physics tweaks and the stricter parrying timing ''long before'' the free downloadable updates released.
313** Game Director Morio Kishimoto [[https://www.famitsu.com/news/202311/08320390.html commented on this in a Famitsu interview]], expressing astonishment and praise at the Western modding community and mentioning how they were considered a "rival" - in the sense of setting a bar for them to overcome - during their development of the free updates, especially ''The Final Horizon''.
314* GameplayAndStoryIntegration: As Sonic frees his friends, he absorbs the energy that powered their cages. While this grants him new abilities, it is also clearly harming him. With every friend saved, Sonic's idle animation becomes increasingly groggy and exhausted. By the time he [[spoiler:makes it to Rhea Island, he can barely stand up]]. Some incidental dialogue also has him express exhaustion and side-effects, up to and including [[spoiler:struggling to remember his friends and even his own name]].
315* GameplayAndStorySegregation:
316** The above being said, Sonic's gameplay isn't directly impacted by his corruption [[spoiler:and when he is cured of his ailment, he keeps the skills that [[CursedWithAwesome are implied to be a result of his cyber-corruption]]]]. Additionally, despite the fact that it is implied that [[spoiler:Tails, Knuckles, and Amy sacrifice their physical forms in reality to save Sonic]], hence why they are not present on Ouranos Island, they still appear in their respective islands, along with any Side Stories the player has missed.
317** Even after [[spoiler:the voice that speaks to Sonic manipulates him into activating the towers and reveals itself as THE END, the game's true BigBad, THE END]] will prevent Sonic from crossing the boundary between Kronos and Rhea Island by telling him he must complete his mission. It's even possible to get their tutorial spiel long after that and interacting with locked devices will yield the same "you are not ready" line from previous islands.
318* GatheringSteam: Cyber Space 4-G from ''The Final Horizon'' has a special gimmick where Sonic's Boost Gauge is replaced by a Rev Gauge. In this level, Sonic's Boost starts a fair bit slower than normal, but as he Boosts the Rev Gauge increases. When the Rev Gauge fills up completely, Sonic gains a speed increase, which is indicated by the giant speedometer at the right side of the screen. This stacks up to three times, with the speedometer maxing out at "TOP" speed. If Sonic stops Boosting, the Rev Gauge will empty and he will lose his speed boost, forcing him to regain it.
319* GenreRoulette: With the soundtrack containing over 150 songs, the music varies depending on what the player is doing.
320** Exploring the islands has a melancholic and moody music that evolves as the player collects more Chaos Emeralds.
321** The Cyber Space Stages take inspiration from DrumAndBass and ElectronicDanceMusic, much like the Avatar stages from ''VideoGame/SonicForces''.
322** The Boss Themes against the Titans are a combination of PunkRock and Metal, with [[Music/SleepingWithSirens Kellin Quinn]] on vocals.
323* GiantFootOfStomping: In the final scene of the reveal trailer, Sonic encounters GIGANTO, whose thundering stomp is so massive that Sonic needed to jump out of the way from being flattened.
324* GetBackHereBoss:
325** The SQUID, SHARK, and FORTRESS Guardians all require Sonic to chase the respective MiniBoss for some time until he can find the window of opportunity to hit them and force them to stop to fight him directly. SQUID releases a purple trail behind itself Sonic needs to run along and dodge energy bullets; SHARK needs to be grabbed by the tail and be held onto as it tries to shake him off and slam him into fired missiles, and FORTRESS leaves behind various rails to grind on that need to be jumped between as they end and/or FORTRESS's projectiles run down them.
326** The second part of the WYVERN boss fight after climbing the tower to even get to it involves running along an energy trail and Homing-Attacking several drones in order to catch up and snatch the final Chaos Emerald from its head. The fight proper has Super Sonic chasing down WYVERN as they fly through the skies of Ares Island while deflecting its missiles back at it to slow it down and force it into direct combat.
327* GodzillaThreshold: Sage suggests to Eggman that asking for Sonic's help is key to his escape from Cyber Space, but he refuses. When [[spoiler:THE END reveals its true colors and threaten to destroy the world]], she believes an EnemyMine can at least give them a chance to defeat it. Eggman then begrudgingly assists Sonic in [[spoiler:gathering the Chaos Emeralds on the final island]].
328* GoldenEnding: While it's not officially stated which ending is the "true" ending to the game, "The Final Horizon"'s take on the endgame is much more positive than the original's BittersweetEnding, but it is locked behind a much harder final world and absolutely demanding combat trials. [[spoiler:In the ending, Sonic completing the trials grants the pilots of the Titans closure and hope again, and Sonic turns his cyber corruption into a new power-up, one that allows him to defeat THE END definitively without having Sage sacrifice herself.]]
329* GoldenSuperMode: Super Sonic as usual, but rather than saving it for the final boss, Sonic actually transforms into his Super form for ''every'' boss. And he needs to, since said bosses are all HumongousMecha that have comparable size and strength to most of the final bosses he's faced, and would hand him his own blue ass on a plate otherwise.
330** [[spoiler:Super Sonic gains a ''second'' form during the battle against SUPREME in the "Final Horizons" version of its boss fight, which he later uses to fight THE END when it possesses SUPREME.]]
331* TheGoodTheBadAndTheEvil: The three major parties seem to follow this scheme:
332** The Good is the titular Sonic, TheHero of the franchise, who is simply trying to rescue his friends from the Cyberspace.
333** The Bad is Sage, Eggman's new AI, who costantly antagonizes Sonic and acts as TheHeavy of the game. [[spoiler: It's eventually revealed that she is simply trying to protect everyone from the real threat listed below. Unfortunately, due to [[PoorCommunicationKills poor communication]] and her programmation by Eggman, who refuses to work with Sonic, she isn't really successful to stop the threat from getting unleashed.]]
334** The Evil is [[spoiler: THE END, a sadistic entity intentioned [[OmnicidalManiac to eliminate all of existence]], [[ManipulativeBastard manipulating everyone else to achieve its goals]], who is also responsible for the destruction of the Ancients' original world. Needless to say that this forces the other two parties to form an EnemyMine against it.]]
335* GreenHillZone:
336** Green Hill itself (specifically its incarnation from ''VideoGame/SonicGenerations'') appears as one of the four Cyber Space themes and is the theme of portal 1-1, which acts as a tutorial stage before you go to Kronos Island.
337** The first island, Kronos Island, consists of widespread grassy plains with rolling slopes, beautiful rivers, and lush forests, and acts as a laidback and easygoing level for you to get accustomed to the open zone gameplay, with the guardians and enemies on the island being easier to fight than on the other islands.
338** The [[spoiler:final two islands — Rheas Island and Ouranos Island — both]] take place on grassy plains similar to Kronos Island and feature many of the same hallmarks as it. This is due to [[spoiler:them [[WhatCouldHaveBeen being]] originally a part of Kronos Island at one point until they were split off into their own islands]]. [[invoked]]
339* GrowingWithTheAudience: ''Frontiers'' marks the franchise's second full foray into maturing with its audience after that of ''VideoGame/SonicAdventure''. The game returns to a DarkerAndEdgier direction by having the Starfall Islands exhibit a sense of loneliness and melancholy and showing flashbacks of the Ancients undergoing genuine tragedy due to a cataclysmic event. After the games from ''Colors'' to ''Forces'' largely ignored the ''Adventure'' games' CharacterDevelopment, this game revisits and reinstates much of the development through Sonic's interactions with the cast. Gameplay-wise, the game relies heavily on open-world elements to give the player more freedom and allow them to decide what to do and where to go as opposed to the more "racetrack" design of its immediate predecessors.
340* GuideDangIt:
341** Strangely applied to a matter outside of gameplay, a lot of Sonic's incidental thoughts and dialogue on friends, locations, and even the plot are passive comments he'll make if he's been exploring the game world for around ten minutes without interruption (such as fighting a Guardian, triggering a story event, or entering Cyber Space). Lines seemingly dummied out, like [[spoiler:Sonic [[LaserGuidedAmnesia slowly forgetting his memories]] when suffering the Cyber-Corruption on Rhea Island]], are extraordinarily hard to even hear because you have to commit to a ViolationOfCommonSense, and avoid interacting with much or potentially even outright idle in a ''Sonic game'' to hear them. Thus, it is entirely possible to complete the entire game without hearing most of these lines.
342** There is one special shape recognized by the Cyloop: Drawing an infinity symbol bestows infinite Boost Gauge for a limited time. Nothing in the game hints that this feature exists, though the ''Speed Strats'' video concerning the Open Zones actively demonstrates and talks about it.
343** There is one Guardian that isn't immediately visible on the overworld despite its map icon, GHOST on Ouranos Island. It can only be triggered by [[spoiler:interacting with the unusual pedestal]]. It also can't be damaged directly at all, and is instead defeated by [[spoiler:Cylooping the additional pedestals it tethers itself to, after you complete a platforming challenge]].
344** The westernmost Island Mystery on Ouranos Island isn't handled the same way as any other Island Mystery or Map Challenge in the game. Unlike all other Island Mysteries, it is not unlocked by a story event and does not have any corresponding cutscene. Unlike Map Challenges, it does not unlock any of the map, and functions only slightly similarly to one other challenge (on Ares Island near the Fishing Spot). Unlike the entire rest of the game, it functions exclusively based on audio clues. Cyber Space Portal 4-7 and a Hermit Koco are "locked" behind it, [[AntiFrustrationFeatures but the game provides three other ways to access them]].
345** The player must start the FinalBoss on Hard mode to access the full boss fight in the base game. If played on Easy or Normal, it will skip straight to the QuickTimeEvent finisher. There is no explicit mention of this in the game itself, outside of the difficulty descriptions vaguely noting Hard Mode includes "something extra". Fortunately, the difficulty can be changed at any point, the game autosaves before the trigger for the final boss, and the autosave file cannot be overwritten or deleted, so it's always possible to try again.
346** The Cyber Space Power Boost, Extreme difficulty mode, and the Spin Dash are unlocked by S-Ranking evey Cyber Space Challenge, Battle Rush, and Action Chain Challenge respectively, but the only indication that this is the case when you've already completed those challenges.
347** In ''Another Story'', Sonic learns a new technique called the Perfect Parry, a version of the Parry that requires precise timing. The game does not inform you that the leniency of the timing window is contingent on game difficulty.
348** ''Another Story''[='=]s new final boss has a few conveyance issues that are not immediately clear. There are hints provided by the Master Koco in an optional dialogue prompt with him before the final boss of the update, but only after the player has fought it once. The first hint is free, but he will only share more hints if the player gets 100% completion on the map.
349*** In the first phase, [[spoiler:the player is locked into an endless fight with THE END controlling the SUPREME Titan]], where it will constantly regenerate its health until the tether is first lodged free from its neck. The problem is that this hint isn't communicated clearly enough, and aiming at the tether can be a problem. The hint given by Master Koco states that "there's something that Sonic can do besides attacking the boss." The best way to get to this tether is by attacking the head once, then using the sidestep to switch targets.
350*** In the second phase, once it's knocked down, the player can aim at its head, or the hole in the back of the Titan that holds the rifle. The player is supposed to use a Quick or manual Cyloop to free the rifle, but nothing points to the relevant weak spot.
351*** Finally, the second phase has [[spoiler:Sage, Tails, Amy, and Knuckles]] putting up a barrier, where the Titan will sometimes go berserk and beat the back of its head rapidly. If this goes on for too long, the Titan will attack and weaken the barrier, with three of these resulting in a game over. Much like the tether phase, the player is supposed to attack, sidestep, and then do a perfect parry in order to get them to stop, which also opens up a Grand Slam chance. There is no indication the player can do this either.
352** In the TITAN fights, you might be prompted into ButtonMashing {{Quick Time Event}}s, such as when WYVERN dives like a flaming meteor and Super Sonic must repel it. Instead of pressing the promped button, you can spin the analog stick to faster, less intensive results. ''Nowhere'' is this method hinted.
353* HackingMinigame: A few special challenges consist of a BulletHell-like game with the objective of destroying the CPU core while evading the light and dark attacks.
354** This is also a potential case of GuideDangIt if you are unaware that you are immune to the color of the bullets you are shooting. Especially in [[spoiler:the base game's Hard-mode True Final Boss.]]
355* HandWave:
356** In ''The Final Horizon'', the reason why Amy uses tarot cards as a weapon rather than her standard Piko Piko Hammer is conveniently explained in a cutscene where it is insinuated that some unknown effects of Cyber Corruption prevent her from using her hammer normally.
357** The open zone elements are given a somewhat loose explanation in ''The Final Horizon'' by Sage telling Sonic that they are Cyber Space constructs manifesting in the real world due to Sonic's strong link to Cyber Space (for some reason). They are also not literally there, meaning that for outsiders like Sage, they don't exist and the Starfall Islands are otherwise completely devoid of floating rails and springs and what have you.
358* HarderThanHard: The "Extreme" difficulty, [[UnlockableDifficultyLevels unlocked after]] getting an S-rank on all [[BossRush Battle Rush]] levels, lives up to its name, making Sonic a OneHitPointWonder (and not just base Sonic either, ''Super Sonic'' also goes down in one hit too) and locking in all his stats at level 1.
359* HardModePerks: If playing on Hard Mode in the base game, [[spoiler:the TrueFinalBoss includes an UnexpectedShmupLevel phase with additional BossBanter]].
360* HereWeGoAgain: The game requires Sonic to complete islands by collecting the seven Chaos Emeralds, so the story forces him to lose them after they've been collected whenever he travels to a new island. This often happens by Sonic getting shot out of the sky by laser cannons.
361* HeroicSacrifice:
362** [[spoiler:Amy, Knuckles, and Tails]] sacrifice their physical forms in the real world in order to save Sonic from [[spoiler:his cyber-corruption]]. Thankfully, this gives Sonic the chance to [[spoiler:fight THE END]], which results in them being freed from Cyber Space for good.
363** At the end of [[spoiler:the fight against THE END in the base game, Sage sacrifices herself to finish THE END off. She gets better, as TheStinger reveals that Eggman was able to recover Sage's data]].
364* HijackedByGanon: Subverted. It turns out Sage is one of Eggman's creations (specifically an A.I. construct) and has UndyingLoyalty to her creator, but Eggman is not at all the main threat.
365* HoistByHisOwnPetard:
366** In the battle against [[spoiler:KNIGHT, Super Sonic uses its own sword to cut it with a single attack, reminiscent of ''VideoGame/SonicAndTheBlackKnight'']].
367** Happens again in the [[spoiler:Final Horizon update, when Eggman uses SUPREME/THE END's own rifle to launch Super Sonic Cyber as a bullet against the mutated Titan and the EldritchAbomination, killing both of them with a ''single shot'']].
368* HolidayMode: The Sonic's Birthday Bash update added a suite of cosmetics to celebrate Sonic's birthday. In addition to a birthday outfit for Sonic, the UI can also be changed to be more colorful and the overworld can be altered to a birthday-themed one with themed reskins for various setpieces (such as boxes, artificial walls, and Kocos) and a special background theme featuring a medley of various Sonic songs.
369* HumongousMecha: The Titans are all these, being enormous robotic entities that Sonic doesn't stand a chance of fighting normally. He's only able to do damage when he has all the Chaos Emeralds and turns Super, and even then they put up a hell of a fight. [[spoiler:It turns out they're actually intended to be piloted and were originally created and empowered by the Chaos Emeralds.]]
370* HurricaneKick: Using the Sonic Boom makes Sonic do rapid circling kicks in mid-air where he can launch a plethora of miniature shockwaves.
371* IdleAnimation: Wait around for a few seconds and all the Koco currently collected will pop up around Sonic. Much later, [[spoiler:Sonic will start to display signs of fatigue as the cyber-corruption affects him, and by the fourth island, he's barely able to stand]].
372* ImpossiblyGracefulGiant: The Titans are all these, which serves to make them even more otherworldly. It's especially blatant in regard to KNIGHT, who can zip around the crater it's found in at incredibly fast speeds and flipping all sorts of middle fingers at the SquareCubeLaw.
373* ImpossibleHourglassFigure: The NINJA enemies take this to an extreme, with waists thinner than their heads accentuated by HartmanHips.
374* InconsistentSpelling: The game's Japanese title in katakana is closer to ''Sonic Frontier'' (ソニックフロンティア), but it is still officially called ''Sonic Frontiers'' in Japanese.
375* IncrediblyDurableEnemies: ZigZagged, while basic enemies can be defeated in a single blow like usual, tougher enemies require multiple hits before going down. The Titans play it straight, being completely invulnerable to anything Sonic does, and even against his Super form's attacks, they can withstand a lot of punishment before going down.
376* InfinityPlusOneSword: As of the Sonic's Birthday Bash update, S Ranking every Action Chain Challenge rewards you with Sonic's signature ability, the Spin Dash. It has the same velocity as the Boost but boasts far superior momentum, allowing Sonic to launch himself across the map at incredible speeds simply by hitting level geometry, and comes with the added bonus of being able to barrel through foes in its path (whereas the Boost lost this feature in this game). Its only drawbacks are that it cannot be used in the air, as attempting to do so halts Sonic's momentum and charges the Spin Dash, and due to the nature of its unlock requirement, it can only be obtained at the very end of the game. Downplayed in "Another Story": the Spin Dash is unlocked for Sonic by default, and the challenges and Cyber Space stages expect you to use it, but it must be unlocked for Amy, Knuckles, and Tails, and it's one of the more costly skills in the skill tree.
377* {{Infodump}}:
378** [[spoiler:Rhea Island]] serves as this in the story, revealing the origins of [[spoiler:the Ancients and the Chaos Emeralds, their LastStand against THE END, and why Sage fought so hard to keep Sonic off of the islands]].
379** ''The Final Horizon'' adds several new cutscenes specifically made to explain oddities and inconsistencies with the game's setting, making it sort of an infodump update.
380* InterfaceSpoiler: The map selection screen is divided neatly into five segments, giving away exactly how many islands the cast will be exploring.
381* InvisibleWall: Mostly averted, as almost anywhere that Sonic can physically reach is playable space. There is, however, a very large invisible wall around the northeast island of Chaos Island, as reaching it would only require the extremely simple task of boosting up the raised drawbridge and jumping. Instead the player is required to follow the story until Sonic gets the quest to lower the drawbridge...which he does by boosting up the raised drawbridge and jumping.
382* IronicEcho:
383** In the beginning of ''Prologue: Divergence'', Knuckles says, "I do things on my own, and that's just how I like it. I don't need anyone else to get by. But sometimes..." before he gets curious about the origins of Angel Island. At the end of the short, [[spoiler:after Sage imprisons him on Ares Island]], he repeats this line, but is unable to complete the sentence.
384** In the game proper, after he's told by Amy to be careful, Sonic replies, "'Careful'? Where's the fun in that?" This is repeated in another cutscene where Tails tells Sonic to be careful, to which Sonic says the exact same thing, albeit in a weaker manner since he's during the corruption.
385* ItOnlyWorksOnce: In the "Final Horizon", [[spoiler:Master Koco warns Sonic that if he overuses his new power to master the Cyber-corruption, he could end up using it all up and lose it entirely. He manages to save its full power for the last moment where he obliterates THE END.]]
386* KickTheDog:
387** While Eggman is humanized more in this game, one particular moment stands out as him being unnecessarily cruel. [[spoiler:Upon seeing Sonic's corrupted state (due to his refusal to back down from saving his friends, causing the energy keeping them prisoner to slowly corrupt him), Eggman ''laughs''. Given that the cyber corruption started when Sonic came into contact with a "weird energy" and it causes Sonic to become weaker the more it spreads throughout his body (to the point that he can barely stand), Eggman laughing at Sonic's state is similar to a {{Jerkass}} laughing at an enemy who's ''dying of a terminal illness''.]]
388** The final boss [[spoiler:THE END is a [[EldritchAbomination cataclysmic being]] that]] [[OmnicidalManiac destroys planets]] as naturally as humans eat breakfast. However, after destroying [[spoiler:the Ancients' entire homeworld]], it goes ''out of its way'' to [[spoiler:follow them to Earth]] and [[LeaveNoSurvivors kill off the remaining members]], just because they had the audacity to survive it.
389* LandShark: SHARK is a shark-like guardian that can swim/burrow in the sands of Ares Island, and comes up when there are any passersby.
390* TheLastTitle: The third and final content update for the game is called "The Final Horizon."
391* LauncherMove: One of Sonic's primary attacks, the Cyloop, allows him to send an enemy upward by circling a trail around them, which he can then follow up with additional attacks. If an enemy has a shield, the attack can also send that shield upwards, exposing them and making them vulnerable to attacks.
392* LeaningOnTheFourthWall:
393** Eggman's audio logs comment on how Tails and Amy are often [[OvershadowedByAwesome overshadowed by Sonic]], which could be read as an acknowledgement of how the mainline games since ''VideoGame/SonicUnleashed'' have eliminated and sidelined much of the series' supporting cast in favor of focusing on Sonic, with the remaining characters like Tails, Knuckles, and Amy reduced to non-playable characters.
394** A conversation between Sonic and Tails in ''The Final Horizon'' have them speculate as to why the volcano control in Chaos Island is designed like a pinball machine. Tails guesses that the engineers were [[JustForFun having a little fun]], as engineers do.
395** One of the conversations with Sage in ''The Final Horizon'' has her reveal that the springs, rails, platforms and other objects in the game world, all that just so happen to be subject to the game's noticeable pop-in, are only visible to Sonic due to his connection to Cyber Space, giving an in-universe justification as to why these elements appear when Sonic is close enough.
396* LessEmbarrassingTerm: Eggman is embarrassed about the previous times he's teamed up with Sonic to defeat a world-ending threat, and initially rejects Sage's suggestion to ally with Sonic again. When Sage finally convinces Eggman that such a team-up is his only chance of survival, Eggman relents but tries to keep his dignity:
397-->'''Eggman:''' Sonic! I hereby induct you into the Eggman Empire and order you to save us all! Understand? This is not an alliance!
398* LethalLavaLand: The third island in the game, Chaos Island, is an ash-filled wasteland that is surrounded by a giant, active volcano in the center. While you never actually go into the volcano itself, the lava rivers that it spews out are a frequent obstacle on the island that the player needs to be careful of when traversing, as unlike most other ''Sonic'' games, falling in means ''instant death'', regardless of how many Rings Sonic has.
399* LevelInBossClothing: GHOST is a Guardian miniboss encountered on Ouranos Island, and the only enemy in the game that you must manually interact with to fight. It can't be damaged by normal means and slowly sucks away Sonic's Rings as long as he's nearby. The goal of the fight is to Cyloop four different statues, which are separated by platforming sections, while GHOST harasses Sonic and tries to slow him down.
400** STRIDER (Ares Island), FORTRESS (Chaos Island), and CATEPILLAR (Ouranos Island) are damaged traditionally, but also include rail grinding platforming sections to be able to do so. Likewise, SQUID (Kronos and Chaos Islands) is also damaged traditionally, but instead includes a traditional run-and-jump platforming section.
401* LongSongShortScene:
402** The Balloon enemy has a unique, minute-long theme for when Sonic is trapped inside of it. However, even if the player takes their time, it only takes less than half of a minute for the drowning theme to start playing (notably, the drowning theme ''only'' plays when inside Balloon; in normal water, you simply get beeping).
403** 4-8's background song "No Pain, No Gain" is one of the longer Cyber Space tracks. The stage itself, however, is the shortest in the entire game, with a normal S-Rank time of 30 seconds. The music doesn't reset when you restart the level, though.
404** The Action Chain Challenge music is four minutes long, but the challenges themselves all have a time limit of one minute. Although the Guardian introductions and their defeats pause the timer, it's still not enough time for the music to start looping.
405** The [[HolidayMode Birthday Bash mode]] replaces the default island music with a medley of bright and energetic songs from across the ''Sonic'' franchise. However, the full medley is '''''thirty-six minutes long''''' and the track restarts if Sonic dies, which means it is incredibly difficult to hear the medley and all of the different songs in one go.
406* LovecraftLite: A fairly dark example, almost verging into CosmicHorrorStory. Throughout the game, Sonic slowly discovers that [[spoiler:the Ancients were aliens forced to flee to Earth with the Chaos Emeralds after their home planet was destroyed by THE END, an incredibly powerful cosmic entity who appears as the greatest fear of anyone who views it and is dedicated to eradicating all life in the universe. It followed the Ancients across the universe to Earth to finish the job, devastating their defenses and shrugging off all attempts to defeat it. It couldn’t be destroyed by the Ancients, and it was only defeated when SUPREME's original pilot took on its corruptive energy and the other three pilots sacrificed themselves to seal it within Cyber Space. When it’s released by Sonic, the corruptive energy leaves Sonic catatonic, trapped between dimensions, and it promptly sets out to finish what it started and destroy the Earth]]. In the base game, [[spoiler:Sonic and Sage, using the Chaos Emeralds and SUPREME respectively, face off against it in orbit and, thanks to Sage's HeroicSacrifice, manage to destroy its corporeal form and save the world from its attacks]]. In the Final Horizon update, [[spoiler:Sonic, with the help of Sage, Dr. Eggman, Tails, Knuckles, and Amy, gather the Chaos Emeralds and take on the trials of the four Masters, allowing Sonic to unlock a new power to face off against THE END and SUPREME. After defeating THE END, Eggman and Sonic finish it off using SUPREME's own rifle, destroying both the Titan and THE END's corporeal form without sacrificing Sage]].
407* {{MacGuffin}}: Sonic's goal is to collect the Chaos Emeralds by collecting Vault Keys from linear stages, which can only be unlocked with Portal Gears (awarded after defeating mini-bosses throughout the map). Notably, this is the first time the Chaos Emeralds have been a major plot device in a 3D main series ''Sonic'' title since 2011's ''Sonic Generations'', after ''Sonic Lost World'' and ''Sonic Forces'' had them become optional trinkets.
408* MediumAwareness:
409** One of Sonic's interactions with Knuckles has them both admit to seeing User Interface elements such as the markers denoting a challenge that uncovers more of the map, attributing them to Cyber Space and the technology of the Ancients. The map itself is referred to as Sonic's own knowledge of the area which grows after completing challenges, since they beam the relative area info straight into his brain.
410** Sage asks Sonic what his end goal is at one point. Sonic comments it's usually a spinning sign or a big ring, the two most common end of stage markers.
411* MemeAcknowledgement: Sega is aware of how difficult players find Cyber Space 1-2 to S-Rank. Owing to this, 1-2 is the ''only'' Cyber Space stage to not have its S-Rank requirement change in the Extreme difficulty introduced in the "Sights, Sounds, and Speed" update.
412* MercyMode:
413** Repeatedly failing the pinball segment at the end of Chaos Island will eventually make the game add glowing arrows at the outlanes and drain that function as a kickback, throwing the ball back in if it lands in, then disappearing for the rest of that ball's life.
414** Should the player fail too many times on [[spoiler:the fight against [[TrueFinalBoss THE END]] in the base game]], the game will give them more extra lives.
415* MillionToOneChance: Sage ran millions of calculations after Eggman gets trapped in cyber space in order to find the best way to protect him from [[spoiler:THE END]], unable to find a way to defeat it and guarantee his safety. [[spoiler:However, once Sonic is saved by his friends after climbing the Rhea Island towers, Sage realizes the one calculation she didn't account for was [[EnemyMine the two enemies working together]]. In the base game, Sonic and Sage succeed in defeating THE END, but at the cost of Sage's life]]. Exaggerated in the ''Another Story'' scenario from the "Final Horizon" update, [[spoiler:where according to Sage, there was one possibility that was so implausible among her millions of simulations, she didn't even consider it. Sonic, a master of overcoming the odds, agrees to this one plan, where she manages to bring all of Sonic's friends back from their digital prison and enact a plan to hopefully defeat THE END]]. This plan goes off without too many hiccups, [[spoiler:in which Sonic and Eggman defeat THE END, this time without needing to sacrifice Sage]].
416* MoneyForNothing: The Memory Token and Vault Key costs aren't as intimidating as they seem. There are many of them both visible and hidden, and Memory Tokens are even a random drop from basic enemies. A good couple of hours of searching, if not one hour, will likely give you more than you need to complete an island.
417* {{Mordor}}: Chaos Island is nearly the spitting image of the TropeNamer. A dismal wasteland with ash falling from the sky, ancient weaponry, and rivers of lava, complete with a volcano as the island's centerpiece.
418* MultiDirectionalBarrage: A Titan's enraged state typically comes with them firing off many, ''many'' weapons littered across their bodies in an attempt to overwhelm Super Sonic rather than merely swat him away.
419* MultipleEndings: While the game always features the same mid-credits scene, the one preceding it changes based on a few factors:
420** The base game's ending is the same whether you complete it on Hard or not. [[spoiler:Sage takes control of the defeated SUPREME and flies it to space, where she and Super Sonic face off against THE END. Though they’re successful in defeating it, their victory comes at the cost of Sage, who sacrifices herself in order to stop a last-ditch attack from THE END. Though Eggman mourns the loss of his "daughter" in silence, completing the game on Hard mode (or with 100% completion on lower difficulties) yields a post-credits scene of Sage being somehow restored by Eggman]].
421** The Final Horizon update's GoldenEnding [[spoiler:has THE END directly assume control of the defeated SUPREME as an avatar, mutating its form and puppeteering it as if it was a feral beast. Empowered by the Cyber Corruption, Super Sonic manages to disarm and later completely destroy THE END, in part thanks to Dr. Eggman taking control of SUPREME’s rifle and using Sonic as a bullet against THE END. Unlike the base game ending, Sage survives all the way through, with the final shot being of her and Eggman watching the starfall together, with no post-credits scene after the mid-credits one]].
422* MusicalNod:
423** The jingle when catching a fish is a short remix of "and... Fish Hits!" from ''VideoGame/SonicAdventure''.
424** The second boss's main theme, "Break Through It All" has a part in the bridge that sounds like a TriumphantReprise to ''VideoGame/SonicForces[='=]'' main theme, "Fist Bump". Specifically:
425--->("Fist Bump") ''Together we can show the world what we can do''\
426''You are next to me and I'm next to you''\
427''Pushing on through until the battle's won''
428--->("Break Through It All") ''Don't stop we're on a mission''\
429''Overdrive and overrun the competition''\
430''Counting up the damage when it's done''
431** The third boss's main theme, "Find your Flame", is almost a reprise to "Through the Fire", especially with how the boss takes the form of a knight, much like the ones Sonic fought in ''VideoGame/SonicAndTheBlackKnight''. More directly, it can also be seen as an antithesis to "Infinite" from ''Forces'', given that it features the same singer (Tyler Smyth) and acts as a heroic BoastfulRap rather than a villainous BreakThemByTalking.
432** The incidental piece "Visions of Home", when Knuckles thinks of Angel Island, contains the melody to Angel Island Zone Act 1 from ''VideoGame/Sonic3AndKnuckles''.
433* MusicalPastiche: The songs for the Cyber Space stages are deliberately made to recall the styles of music from older ''Sonic'' games, with standout examples being [[https://www.youtube.com/watch?v=oO-YIVPps00 "Flowing"]] (''VideoGame/SonicR''[='s=] techno-house vocal songs), [[https://www.youtube.com/watch?v=EX7i1Esr8DM "BMB"]] (''VideoGame/SonicTheHedgehogCD''[='s=] rave-inspired JP/EU soundtrack), [[https://www.youtube.com/watch?v=YF16PLPDqWI "Ephemeral"]] (''VideoGame/SonicTheHedgehog2006''[='s=] drum-and-bass-influenced songs), and [[https://www.youtube.com/watch?v=xNLEqECDgyA "Fog Funk"]] (''VideoGame/SonicAdvanceTrilogy''[='s=] chiptune and ''VideoGame/SonicRush''[='s=] funky sample-heavy tracks).
434* MysticalWhiteHair: Sage, a mysterious digital-looking girl, is shown to have white hair.
435* MythologyGag:
436** One of the moves, Spin Slash, was originally planned to appear in the canceled ''VideoGame/SonicXTreme''.
437** There are several for the [[Film/SonicTheHedgehog2020 first live-action film]]:
438*** When Sonic hits his ring cap, he begins to surge with blue electricity like his feature film counterpart and hits maximum potential speed, complete with glowing blue irises; the brief cutscene of Sonic entering the Power Boost mode is shot nearly identically to his EleventhHourSuperpower moment in the same film.
439*** One of the moves Sonic performs on the SUMO enemy is heavily reminiscent of the "Light Speed Attack" he makes during his final confrontation against Dr. Robotnik.
440*** During the fight against WYVERN, two scripted events involve Super Sonic being surrounded by a barrage of missiles before toying with them in BulletTime if the player hits the [[PressXToNotDie timing input]].
441*** Starting the "Final Horizon" involves Sonic jumping through a giant ring portal which looks just like the ones created from his rings in the movie.
442** Sonic comments on Tails flying with his butt, similar to his "Butt-copter" remark in the [[Film/SonicTheHedgehog22022 second film]].
443** This isn't the first time that [[VideoGame/SonicAndTheBlackKnight Sonic faces a Black Knight armed with a sword]].
444** Portal 2-6 is strongly reminiscent of Sky Rail from ''VideoGame/SonicAdventure2''. In the original game, Sonic is playable in the 2-Player Mode of ''Battle'' and pre-release material shows that Sonic was meant to be playable in the Story Mode of Sky Rail.
445** Radical Highway from ''VideoGame/SonicAdventure2'' once again returns as a playable level in a [[VideoGame/SonicGenerations game where Sonic literally runs through his memories]] despite the fact that it was one of ''Shadow's'' levels, not his, and thus he should not have memories of it since he was never there in the first place.
446** Sonic ends his first conversation with the Elder Koco with [[WesternAnimation/SonicTheHedgehogSatAM "Let's do it to it!"]] Sadly, it's not voiced. [[spoiler:He DOES, however, get a voiced instance of the line later, when speaking with Sage in the main game's side story, and again in ''Another Story'' from the Final Horizon update when he agrees to try out Sage's plan]].
447** During one of Eggman's rants to Sage, he says [[WesternAnimation/AdventuresOfSonicTheHedgehog "I hate that hedgehog!"]]. Similarly, in one of his Egg Memos, he recounts a joke Sage told him about Sonic, the punchline being [[WesternAnimation/SonicTheHedgehogSatAM "He's the fastest thing alive!"]].
448** By the time he reaches [[spoiler:the fourth island]], Sonic has completely run ragged and is struggling to move forward (at least in the cutscenes), thanks to endless running and [[spoiler:cyber-corruption from rescuing his friends]]. It's not every day that he is seen like this, but the last time he was this tired was [[ComicBook/SonicTheHedgehogIDW when he fought off and nearly succumbed to a dangerous artificial virus, bioengineered by Eggman.]]
449** One of the obtainable New Koco added in the Sonic's Birthday Bash update is a Koco with a miniature [[VideoGame/SonicAndTheBlackKnight Caliburn]] strapped to its back.
450** During its [[spoiler:conversion by THE END in the Final Horizon update, SUPREME grows extra arms from its body. [[Videogame/SonicUnleashed Sound familiar?]]]]
451** The Grand Slam used on [[spoiler:SUPREME/THE END]] in "The Final Horizon" has Super Sonic [[BadassArmfold cross his arms]] before nonchalantly [[SpeedBlitz assaulting the boss]] until it collapses, with Super Sonic standing over them in the same pose. This is similar to how Super Sonic takes down [[spoiler:Giant Zavok]] in the finale of the [[ComicBook/SonicTheHedgehogIDW IDW comics]]' Metal Virus Saga.
452** The way that both [[spoiler:the SUPREME Titan and THE END itself]] are defeated. [[spoiler:Super Sonic is fired out of a cannon to ram right into them, similar to the Sonic Power Cannon from the third season of ''Sonic X''. Ironically, this is done by the heroes here to ''prevent'' someone close to them needing to perform a HeroicSacrifice so that EverybodyLives, such as Sage being in the same situation as Cosmo which does play out in the base game's ending]].
453[[/folder]]
454
455[[folder:N - Y]]
456* NewGamePlus: After the "Sonic's Birthday Bash" update, defeating the base game's final boss unlocks New Game+ (beating ''Another Story'''s final boss will also unlock it if the player hasn't beaten the base game's final boss after the "Birthday Bash" update). Sonic can carry over any unlocked upgrades (including the Spin Dash) and any stat levels, but cannot bring items.
457* NinjaRun: Sonic does the "Both arms held behind back" run when running at full speed, the Ninja enemies also use this pose during their run animations.
458* {{Nerf}}:
459** Sonic's Boost no longer lets him barrel through enemies unimpeded and is limited through a StaminaMeter now as opposed to Rings or White Wisps. On the upside, it automatically recharges by itself when running normally, instead of needing Rings or White Wisps. In addition, Sonic cannot maintain an Air Boost at all until Speed is leveled up to Lv. 99.
460** The Sights, Sounds, and Speed Update additionally nerfed Big's fishing minigame by drastically increasing all of his shop prices, making it significantly more difficult to skip content by playing the minigame.
461** The "The Final Horizon" update has the Parry nerfed under Amy, Knuckles, and Tails' control, leaving it so it only lasts a few seconds rather than being able to be held indefinitely. And by extension, [[spoiler:the Perfect Parry unlocked for Super Sonic in the story's final act forces the player to rely on perfect timing for the parry rather than just being able to hold it down]].
462* NitroBoost: In addition to the standard Boost, two of the Cyber Space levels in ''The Final Horizon'' introduce a brand-new gimmick called the Rocket Boost. Sonic can only Rocket Boost when he collects a green capsule, and when he does so, Sonic blasts off automatically at an even faster speed than Power Boost speed with a flaming Boost trail. Rocket Boost additionally lets Sonic plow through enemies, which the normal Boost cannot do in this game. Rocket Boost lasts until the green Boost Gauge runs out or Sonic launches off the ground in any way except jumping, which ends the Rocket Boost and requires Sonic to pick up another capsule.
463* NoCartoonFish: The fish and other catches in the fishing minigame with Big the Cat look realistically designed with no anthropomorphic qualities to speak of. Some catches may have unusual colors or be gold plated, but it's entirely possible to end up with Sonic and Big posing next to a realistic alligator or coelocanth.
464* NoFairCheating: {{Downplayed|Trope}}. Certain powerful techniques can be used in Cyber Space, but doing so will mark your completion time with a colored asterisk. These include the [[AscendedGlitch Homing Dash]] (white), Spin Dash (red), altering the Deceleration Rate sliders in Options (yellow), and using the Power Boost (blue). However, you are otherwise not penalized for using said techniques, giving you free reign to tamper with Cyber Space however you please.
465* NonIndicativeDifficulty: The game offers three difficulty levels at launch, but the difficulty seems to affect little besides how many Rings you lose when you're hit by enemies, which becomes a non-issue as you upgrade your Ring capacity. The only other notable difference is that playing on Hard gives you a TrueFinalBoss '''fight''' instead of a QTE scene against it, and aside from that, the overall experience is essentially the same regardless of difficulty, and you can switch between them on the fly. The first update adds a fourth difficulty level to remedy this, Extreme. Extreme difficulty cannot be changed into or out of once a playthrough is started, locks Sonic's stats at level 1, and makes it so that [[OneHitPointWonder Sonic goes down after taking just a single hit from anything, regardless of how many rings he has-]] and ''Super Sonic is not exempt from this.'' It also makes the time required to S-Rank the Cyber Space Stages (except 1-2, which is already infamously difficult) far more stringent and unforgiving. In order to unlock this dificulty, you must S-Rank all of the Battle Rush stages.
466* NonIndicativeName: The "Fish-o-pedia" menu not only has non-fish animals like sharks, turtles and alligators but also inanimate objects.
467* NonstandardGameOver: As Super Sonic, you're pretty much invincible[[note]]Except in Extreme Difficulty, where even Super Sonic is not exempt from being turned into a OneHitPointWonder[[/note]]. That said, like other ''Sonic'' games, you turn back to normal when you're out of ring power. The consequences of losing Sonic's super form against a Titan are unique and not pretty (such as the first Titan eating Sonic alive). This also applies if you fail certain quick time events.
468* NostalgiaLevel: [[VideoGame/SonicTheHedgehog1 Green Hill]], [[VideoGame/SonicTheHedgehog2 Chemical Plant]], and [[VideoGame/Sonic3AndKnuckles Sky Sanctuary]] make a return as Cyber Space levels. Some of the Cyber Space levels are also recreations of stages from ''[[VideoGame/SonicGenerations Generations]]'', and some harken back to stages from past games, such as [[VideoGame/SonicAdventure2 Sky Rail]] and [[VideoGame/SonicUnleashed Savannah Citadel]]. [[spoiler:This is {{Invoked}} in-story, as Cyber Space used Sonic's memories to help him escape from the realm by giving him familiar ground to tread through.]]
469* OOCIsSeriousBusiness:
470** In most cases, Sonic is typically embracing whatever kind of danger he genuinely fools around with while casually quipping in a composed demeanor as usual. Throughout this game's story, his expressions seem to be rather incredibly flummoxed and a little intrigued from what he's seeing around him after avoiding certain death. The last shot of the reveal trailer even shows him being highly cautious yet determined after examining the Titan in front of him, almost as if he's unsure if he'll actually pull through to defeating it or not.
471** In TheStinger of the base game, Eggman quietly works to [[spoiler:restore Sage to one of his computers]], rather than him [[LargeHam hamming it up]] as usual.
472* OnceMoreWithClarity: Whenever Sonic defeats a Titan, [[spoiler:he gets a vision of an Ancient reacting to something. When he unlocks all of the towers on Rhea Island, the Ancient's LastStand against THE END is shown, revealing that those flashbacks were the memories of the Ancients who piloted those Titans, reacting to the SUPREME Titan sealing THE END away.]]
473* OntologicalMystery: The plot of the game. The protagonists, while trying to locate the Chaos Emeralds, end up trapped in a strange new land, unsure how or why they ended up there. To add onto the mystery, they encounter remnants from an ancient civilization that even predates the Echidna tribes.
474* OriginsEpisode: The game ultimately serves as one for the Chaos Emeralds, and by extension the Chao and Chaos, the God of Destruction. [[spoiler:The Emeralds were brought to Earth by the Ancients, alien {{Precursors}}, who came to Earth while fleeing from [[EldritchAbomination THE END]] and coming into contact with the Master Emerald. After THE END destroyed what was left of their civilization, a faction of surviving Ancients left the Starfall Islands to roam the earth, and prolonged exposure to a certain kind of radiation ended up heavily mutating their DNA and causing them to devolve into the Chao. In turn, a certain Chao's exposure to the Master Emerald ended up causing it to turn into Chaos, partially restoring its original form as an Ancient.]]
475* OxygenMeter: Sonic gains a more traditional one in this game that appears anytime he's underwater compared to all other games that only show a countdown [[AlmostOutOfOxygen when he's close to drowning]]. This game's meter drains at a much faster pace, but this can mostly be brushed off due to the game's lack of mandatory underwater terrain. The original countdown (and its [[SongsInTheKeyOfPanic accompanying music]]) now only appears when you allow Sonic to be trapped inside the water of a bulbous heart-like enemy for too long.
476* PaintingTheMedium: The pinball minigame on Chaos Island is an ancient artifact that predates Sonic. To reflect this, the music is a {{chiptune}} track done in the style of ''VideoGame/FantasyZone'' and ''VideoGame/OutRun'' -- Sega games that predate Sonic.
477* PaletteSwap: The FinalBoss is one of the first boss; [[spoiler:SUPREME may have a different head and extra equipment for flying, but it has an identical build and design to GIGANTO otherwise]].
478* PictorialLetterSubstitution: The "O" in "Frontiers" is replaced with a Portal.
479* PlugNPlayTechnology: In "The Final Horizon", [[spoiler:THE END launches a tether plug at SUPREME to possess it, while Eggman has his own one which allows him to aim and fire SUPREME's rifle.]]
480* PoorCommunicationKills: Sage's refusal to explain to Sonic that he's [[spoiler:freeing THE END]]. Since she's an Eggman construct given physical form, she's unlikely to trust his arch-nemesis, but considering [[spoiler:the [[CosmicHorrorReveal enormity]] of what he is unwittingly doing]], she should have said ''something'' about it.
481* PressXToNotDie: During the ActionCommands in the battles with the Titans, failing to pull off some of them will lead to either a further delay in the fight, and some result in Super Sonic ''dying''. In particular:
482** Failing the prompt when Sonic has to open up GIGANTO's mouth leads to him being crushed to death by its teeth.
483** In the battle with WYVERN, should the player fail the prompts to get Super Sonic to avoid the missiles, he'll be crushed and blown to nothingness by them.
484** If any of the sword-based prompts with KNIGHT are failed, Super Sonic ends up getting crushed by KNIGHT's sword.
485** In the final battle of the base game, if the player fails to get any of the final prompts, [[spoiler:Super Sonic comedically has an OhCrap reaction as he faceplants into THE END.]]
486* PromotedToPlayable: "The Final Horizon" update adds Amy, Knuckles, and Tails as playable characters in a unique story scenario. It is also the first time these characters have been playable in a mainline 3D ''Sonic'' game since ''VideoGame/SonicTheHedgehog2006''.
487* RagnarokProofing: The Ancients built their technology to ''last''. Despite vastly exceeding the age of previously established ancient societies like the Echidna and Babylonian empires, nearly everything that the Ancients built remains in perfect working order, including an entire virtual dimension and an army of giant robots. [[spoiler:All this is even despite other factions having had possession of the Chaos Emeralds, which all that technology used as its primary power source.]]
488* RapidFireFisticuffs: A new part of Sonic's moveset is the ability to follow up homing attacks with rapid-fire punches and kicks. With "Phantom Rush" activated, Sonic incorporates {{Flash Step}}s in to increase his damage output.
489* ReflectiveEyes: At one point in the reveal trailer, a glimpse of Sonic's pupils shows GIGANTO being reflected from them.
490* ReligiousAndMythologicalThemeNaming: The individual Starfall Islands take their names from Myth/ClassicalMythology, in particular figures related to the Titans.
491** The first island, a grassy island, is named "Kronos Island", after the leader of the Titans of Greek myth. [[spoiler:The "fourth" island, in reality the at first inaccessible far side of Kronos Island, is named "Rhea Island" after Kronos' wife]].
492** The second island, a sprawling desert warzone, is named "Ares Island" after the Greek god of war.
493** The third island, a desolate mountain range with a volcano in the background, known as "Chaos Island", after the primordial source of all things in Greek myth.
494** Another island, [[spoiler:the fifth]], is named for the father of the Titans, Ouranos.
495* RemixedLevel: The nine Cyber Space levels featured in ''The Final Horizon'' are arranged versions of existing Cyber Space levels in the base game. Each one is radically changed by adding a truckload of platforms and obstacles such that they are virtually unrecognizable from the original versions and become extraordinarily bigger and more open in scope, and each one has a special gimmick attached to it to change things up, such as green capsules that give Sonic a temporary Rocket Boost, hidden mines that explode when touched, a instant kill time bomb strapped to Sonic, or low gravity. Instead of collecting 5 Red Star Rings, you must instead collect three different types of collectables: [[VideoGame/SonicLostWorld Number Rings]][[note]]Must be collected in order from 5 to 1[[/note]], Animals[[note]]Must be found and carried to a safe zone; Sonic can only jump and use dash panels when carrying them[[/note]], and [[VideoGame/SonicForces Silver Moon Rings]][[note]]Must be collected within a short time frame[[/note]], some of which are on mutually-exclusive pathways and necessitate replays.
496* RememberTheNewGuy: While they were given proper introductions in their source material, Tangle and Sticks are casually mentioned as if they were always part of the Modern Sonic universe.
497* TheReveal:
498** In ''Prologue: Divergence'', Knuckles mentions the Master Emerald shrine apparently existed ''before'' Pachacamac's clan did.
499** It is revealed that [[spoiler:the Chaos Emeralds were first owned by the Ancients, who were an alien race who came to Earth to escape from THE END, who destroyed their home planet, as well as because of the Master Emerald drawing the Chaos Emeralds in.]]
500* {{Roboteching}}:
501** Wild Rush is a homing kick attack wherein Sonic zigzags wildly and rapidly while homing in on his target. It is described as a good way to inflict damage while evading enemy attacks.
502** [[spoiler:The CoupDeGraceCutscene against THE END in ''Another Story'' involves a corrupted Super Sonic bouncing wildly across thin air as he charges into SUPREME and subsequently THE END with sheer kinetic force.]]
503* RunningGagged: Sort of. Since ''VideoGame/SonicColors'', all of the games' [[TheStinger post-credit scenes]] (with the exception of ''VideoGame/SonicForces'') have had a scene with Eggman that's PlayedForLaughs. [[spoiler:The one featured in the base game's GoldenEnding has no trace of comedy whatsoever, with Eggman working to restore Sage]]. The ''Another Story'' scenario doesn't have a post-credits scene at all [[spoiler:but does feature Eggman and Sage going home together, since her sacrifice doesn't happen in this ending]]. It still puts the kibosh on the aforementioned running gag, however.
504* SadBattleMusic: In stark contrast to the Titan battles all having intense rock music for their battle themes, the final boss theme against [[spoiler:THE END]] in the base game is full of piano solos and melancholy synthesizers, driving home the scale of the fight and [[spoiler:Sage's impending sacrifice]].
505* SceneryPorn: There's a ton of it everywhere on each island, from sprawling fields of ruins to dusty dunes.
506* ScrewThisImOuttaHere: Following his disastrous first fight against GIGANTO as normal Sonic, followed by an epic victory against it as Super Sonic, the smartest move he can make against each of the remaining Titans is to retreat until he can gather the Chaos Emeralds and go Super once more.
507* SerialEscalation: Super Sonic is typically a late-game reward for collecting all of the Chaos Emeralds in Special Stages or the EleventhHourSuperpower against a BigBad that Sonic is unable to defeat. In ''Frontiers'', however, not only is getting the Chaos Emeralds a key part of the narrative, but ''all four'' of the colossal Titans upon the Starfall Islands are too powerful for Sonic to face head-on, requiring him to use this typically ending-reserved power to face ''all'' of them. And even then, they don't go down in one or two attacks like previous foes, they all can withstand significant amounts of punishment before finally going down.
508** And that's not to mention where in "The Final Horizon" update, where [[spoiler:by forging the cyber corruption into a new power, Super Sonic can attain effectively a new form above his own]].
509* SequelHook:
510** At the end of the game, [[spoiler:Amy, Knuckles, and Tails all make plans to pursue their own adventures: Amy plans a road trip with Cream and Sticks, Knuckles decides to leave Angel Island to explore the world, and Tails is off to strike out on his own. They promise that they will be very different people when they meet Sonic again.]]
511** Throughout the game Eggman schemes to use the technology of the Ancients for his next plan despite being trapped within its Cyber Space. In TheStinger of the base game, [[spoiler:Eggman manages to save Sage by uploading her data into his [=EggNet=]. The computer he is working on shows the symbols associated with the Ancients, implying that she may have kept some data from Cyber Space.]] The ''Final Horizon'' ending changes it to show [[spoiler:Eggman and Sage deciding to go home, while Sage has fully converted to a blue and white avatar, showing that she has kept the changes Cyber space and the adventure as a whole have done to her]].
512** Finally, there's still the mystery of [[spoiler:what exactly the Master Emerald is, as it was revealed that it predated the Ancients' (and thus the Chaos Emeralds') arrival on Earth, and in fact drew them towards the planet in the first place.]]
513** In ''The Final Horizon'', one of Amy’s conversations with Sage finally reveals what the mysterious zigzag and circle symbol seen across the game means. According to Sage, the symbol represents [[spoiler:a god the Ancients worship. Sage posits the god might even exist in the present]]. There’s a close-up on Sage’s face to accentuate her positing, which suggests the matter may be explored in a future game.
514* SequenceBreaking:
515** The trigger to start the WYVERN boss fight is activated by Homing Attacking its body. The intended way to do this is to collect six Chaos Emeralds to unlock the big tower on Ares Island, which will give you enough altitude to intercept WYVERN and start the fight. However, the ability to Homing Attack WYVERN is always available as soon as the WYVERN event happens, meaning it is entirely possible to start the fight at any time if you can get enough height to intercept it. This isn't intended to be possible until you've collected six Chaos Emeralds, but by using physics exploits you can launch Sonic at such high velocity that you fly high enough to get within range of WYVERN, allowing you to skip getting the Emeralds entirely since there are no other checks to see if you've made the correct amount of progress.
516** In general, the platforming challenges are not made with the Power Boost or the option to maintain boost during a jump in mind, and having either one allows Sonic to reach the key items at the ends of many tracks without having to actually do most or all of the challenge.
517** In the ''Final Horizon'', the trio's boosted Power Boost skills trivialize the majority of their platforming challenges (Tails's can ride the Tornado and go upwards at high speed, Knuckles can hover without losing altitude, and Amy's can cover a long distance to expand her high jumps and slow descents).
518* ShieldBearingMook: One of the robot mooks is covered by a shield that is invulnerable to Sonic's attacks.
519* ShiftingSandLand: The second island in the game, Ares Island, is a desert wasteland surrounded by cliffs and ruins, containing enemies that will occasionally pop out of the sand to attack Sonic (such as the SHARK guardian). Sonic occasionally remarks that it reminds him of [[VideoGame/Sonic3AndKnuckles Sandopolis]] or [[VideoGame/SonicUnleashed Shamar]].
520* ShownTheirWork: The pinball minigame on Chaos Island is one big homage to the EM (electromechanical) era of pinball and has a layout that was standardized by its later decades of the 70s and early 80s: two flippers at the bottom that face each other with a drain between them, a pair of slingshots[[note]]triangular bumpers that propel the ball from the side facing the center of the playfield[[/note]] above and to the side of them, a pair of inlanes leading to the flippers, a pair of outlanes leading to the drain, insert lights along the inlanes and outlanes that shift by pressing the flipper buttons, score multipliers, and PinballScoring. There are even what appear to be leaf switches below the insert lights.[[note]]These are lever-like mechanisms that detect the ball's location; real pinball machines can have dozens of switches of various sorts all over the place[[/note]] Failing the minigame enough times will activate a kickback on the outlanes,[[note]]a solenoid that detects the ball falling into an outlane and propels the ball back into play[[/note]] which, as is standard for pinball games, deactivates once used. Particular flipper techniques done by experienced pinball players can be done in this minigame too. Possibly to avoid overcomplicating things, however, the playfield's layout is much simpler and shorter than most real-life pinball machines of this era.
521* SkillScoresAndPerks: Sonic can upgrade his Speed, Power, Defense, and Ring Capacity up to 99 levels by collecting certain items, as well as gain new skills and abilities through earning EXP or progressing through the story. Tails, Knuckles, and Amy can do the same in the Final Horizon update.
522* ShoutOut:
523** GIGANTO is a walking reference to ''Anime/NeonGenesisEvangelion'' [[note]] [[Creator/{{Sega}} SEGA]] was one of Evangelion's sponsors after all[[/note]] , with its bizarre proportions, SlasherSmile, and being ostensibly piloted by a [[ReiAyanamiExpy young girl with a robotic demeanor]]. The shot of it grabbing Sonic during their first encounter is framed identically to the scene of Unit-01 grabbing Kaworu.
524*** Bonus points for said young girl sharing the exact same voice actress (in [[Creator/RyanBartley English]] ''and'' [[Creator/MegumiHayashibara Japanese]]) as Rei.
525*** GIGANTO's ''Evangelion'' ShoutOut is complemented by the FinalBoss [[spoiler:SUPREME, a PaletteSwap of GIGANTO carrying an immense laser rifle in much the same way as the Evas' various ranged weapons]].
526** When GIGANTO throws Sonic into the mountain, the framing and camera shots are identical to the way Vajra Wyzen attempts to throw Asura into a mountain in ''VideoGame/AsurasWrath''.
527** When GIGANTO is at half-health, it activates an array of laser beams from its back in a similar manner to ''Film/ShinGodzilla''.
528** The second boss, WYVERN, has an appearance that is a mix of an eel and a robot, and looks like something that came from ''VideoGame/HorizonZeroDawn''.
529** The fight against [[spoiler:THE END's second phase (as well as the hacking minigames preceding it)]] is a homage to ''VideoGame/{{Ikaruga}}'', down to the same gameplay mechanics from said game. [[spoiler:THE END's]] overall role in the story isn't too dissimilar to [[spoiler:the Stone-Like, the overall GreaterScopeVillain of ''VideoGame/{{Ikaruga}}'' and ''VideoGame/RadiantSilvergun'']]
530** [[spoiler:THE END's form in the final fight as [[ThatsNoMoon a giant moon]]]] is at least a ''little'' reminiscent of [[WesternAnimation/TheTransformersTheMovie Unicron]].
531** While Sonic Boom has [[Franchise/StreetFighter a rather familiar name]] (bonus points for Sonic and Guile debuting around the same time), it's functionally closer to [[BeamSpam Sonic Break]].
532** Starting from Chaos Island, one challenge variety has Sonic replicating a model made out of colourful blocks that often look like the ones from ''VideoGame/{{Tetris}}'', which when placed on the podium, even jerkily move downwards one "block" at a time.
533** The [[spoiler:final battle against SUPREME/THE END in the Final Horizon update has THE END's moon form hovering over Ouranos Island]], being very similar to ''VideoGame/TheLegendOfZeldaMajorasMask''.
534** There are multiple references to ''Franchise/DragonBall'':
535*** [[https://youtu.be/TEY9IudTkHA A video released to promote the first update]] starts by quoting an infamous line from the original Creator/{{Funimation}} dub of ''Anime/DragonBallZ''.
536---->'''Narrator''': Yes, YES! I can win! I feel great! I can do this!
537*** When Super Sonic defeats GIGANTO, he plunges straight through his chest, just like when Goku does the same thing to King Piccolo in ''Manga/DragonBall''.
538*** Sonic harnessing extra power to achieve an even stronger Super form is very similar to the concept of the different levels of Super Saiyan. The specific form introduced in ''Frontiers'' is even labeled "Super Sonic 2" in the game's code.
539** The TrueFinalBoss against [[spoiler:THE END SUPREME]] [[VideoGame/TheLegendOfZeldaTearsOfTheKingdom features dark orbs which can be knocked away with the right power and timing, but getting hit permanently reduces your maximum health]] (or ring count in this case).
540*** In the final cutscene of this fight, [[spoiler:Super Sonic Cyber is launched to pierce through both SUPREME and THE END, gaining spiral-like irises as he is fully enveloped in the cyber-energy - referencing [[Manga/GetterRobo the Shine Spark and the Getter Ray exposure effects]]]].
541* SoProudOfYou:
542** After seeing how the experience has made Tails wonder how useful he really is, Sonic takes a moment after they help some Koco to assure Tails that he's proud of him.
543** Eggman says he's proud of Sage after she saves him from some Cyber Space enemies in one cutscene.
544** In the ending cutscene of the The Final Horizon update, [[spoiler:Eggman commends Sage for a job well done, and then offers his hand so the two of them may go home together]].
545* SortingAlgorithmOfThreateningGeography: The Starfall Islands that Sonic visits become more treacherous in terrain as he progresses through them.
546** Kronos Island is an idyllic GreenHillZone with rolling slopes, verdant plains, and lush forests.
547** Ares Island is a ShiftingSandLand with vast deserts and scattered ruins.
548** Chaos Island is a LethalLavaLand with desiccated grey wastelands surrounding an active volcano.
549** Subverted with [[spoiler:Rhea and Ouranos Islands]], which share Kronos Island's aesthetic, but host the most powerful tier of enemies for Sonic to contend with.
550* SpannerInTheWorks: Sage ran through countless calculations but was never able to find one where [[spoiler:everyone survives THE END being unsealed]]. This changes, however, when she realizes that she never calculated [[EnemyMine Sonic and Eggman working together]], due to her creator refusing to authorize any alliance with the hedgehog.
551* SprintMeter: The Boost Gauge works this way, depleting whenever Sonic is using the Boost/Spin Dash and quickly replenishing when he is not. Starting from the "Sonic's Birthday Bash" update, finding the special New Koco and bringing them to Elder Koco will add one extra gauge to the Boost Gauge, up to four additional times. Amy, Knuckles, and Tails all have their own boost gauges when they are playable in the third update.
552* StatusQuoIsGod:
553** {{Deconstructed}} in the main plot. [[spoiler:As Sonic travels the islands and rescues his friends, each one comes to realize that they have so much potential, but they are bound by certain things: Amy wants to show the world her love like Sonic does, but selfishly sticks to him; Knuckles wants to explore the world like Sonic can, but feels duty-bound to constantly protect the Master Emerald; and Tails wants to be as strong as Sonic, but finds himself sticking to Sonic's shadow as his "sidekick". Two of the Egg Memo logs also have Eggman note that Tails and Amy would be much more dangerous threats to his plans if they weren't glued to the hip with Sonic. Sonic's heroics and reassurances convince them to take the first step into their new way of thinking]].
554** {{Averted}} in the GoldenEnding and "The Final Horizon" Update. Respectively, [[spoiler:Eggman is shown in TheStinger to have successfully reactivated Sage after her HeroicSacrifice]] or [[spoiler:Eggman and a surviving Sage agree to go home together after the FinalBattle, affirming their status as father and daughter]], thus [[spoiler:keeping his newfound daughter instead of reverting to his usual antics with Orbot and Cubot]] by the end.
555* SupermodelStrut: The NINJA Guardians and their variants perform this during all their slow walk animations, walking with one foot in front of the other complete with swiveling hips. Exaggerated to the point that even during their idle stance, their legs still remain crossed.
556* TheStinger: The last scene after the credits for the base game shows [[spoiler:Eggman successfully bringing back Sage after the latter sacrifices herself to destroy THE END]].
557* SwordPointing: KNIGHT, the Titan of Chaos Island, gets in more than a few pointers towards Sonic. During [[spoiler:the finish of the fight]], Super Sonic manages to pull a "Brave Perspective" pose with [[spoiler:KNIGHT's sword, which is tall enough to be a ''skyscraper.'']]
558* SympatheticVillainDespicableVillain: While the game's initial [[TheHeavy Heavy]] is Sage, who works for long-time villain Dr. Eggman, she's simply following her prime directive to save Eggman, who reciprocates with fatherly love. However, misunderstandings between her and Sonic allow a bigger threat to emerge. [[spoiler:Said threat, The End, is a sadistically [[KnightTemplar self-righteous]] destroyer of civilizations.]]
559* ThematicSequelLogoChange: The bottom portion of the logo is partially broken up and has a Portal replacing the "O" in "Frontiers" to represent the game's Cyber Space levels.
560* ThemeMusicPowerUp: Used with prejudice for the ClimaxBoss of the game, [[spoiler:SUPREME]], albeit a version that starts with an instrumental version, before the vocals kick in during the second phase, ''[[VideoGame/MetalGearRisingRevengeance Metal Gear Rising]]'' style.
561* ThrowingYourShieldAlwaysWorks: One of the robot mooks is able to throw its shield at Sonic like a boomerang. Unfortunately for it, it also exposes itself by doing this, allowing Sonic to attack it if he's quick enough. KNIGHT similarly employs its shield as a thrown buzzsaw, which like its lesser kin is its biggest weakness.
562* TimedMission: One of the new Cyber Space levels in ''The Final Horizon'' has a bomb attached to Sonic with a detonation timer appearing on the screen. If the timer runs out, the bomb explodes and Sonic dies instantly, but the timer can be extended by picking up clocks scattered throughout the stage.
563* TitleDrop: "I'm Here", the game's opening theme, contains the lines "Reaching far across these new '''frontiers'''" and "All across these new '''frontiers'''".
564* TornadoMove: One of Sonic's new unlockable moves is rapidly spinning around a target to shred their health off and rack up hits.
565* TriumphantReprise: For the credits for "The Final Horizon", [[spoiler:a lyrical version of the original melancholic final boss theme, "I'm with you", plays, a heartfelt song dedicated to Sage finally finding a home with Eggman]].
566* TrueFinalBoss:
567** Playing the game on Hard Mode (or changing the difficulty before the fight against SUPREME) allows the player to fight [[spoiler:THE END's second phase]].
568** Completing the story of "The Final Horizon" [[spoiler:allows the player to battle a new version of SUPREME that THE END takes over, continuing the standard Super Sonic style battle rather than changing to a BulletHell-style minigame]].
569* UnexpectedShmupLevel: Halfway through the game, Sonic is introduced to hacking consoles, which feature a minigame that can be summed up as "''VideoGame/NierAutomata'' and ''{{VideoGame/Ikaruga}}'' in a blender". Sonic must use a flying ship to shoot at a stationary orb while using Light Shots and Dark Shots to cancel out and absorb enemy bullets of the respective colors. [[spoiler:Doubles as {{foreshadowing}} for the TrueFinalBoss in the base game, which is fought the exact same way but with Sage and Super Sonic replacing the hacking ship, and THE END replacing the little target orb]].
570* TheUnfought:
571** [[spoiler:Dr. Eggman is never fought either directly or indirectly at any point, making this one of the very few games where Sonic never clashes with his archenemy. Justified, as Eggman spends most of the game trapped in Cyber Space, and by the time he gets out, he's forced to form an EnemyMine with Sonic since The END has become too much of a threat to ignore.]]
572** To a lesser extent, [[spoiler:Sage. While she attacks Sonic by siccing the titans on him, Sage herself is never fought directly, with her instead giving Sonic cryptic warnings and refusing to elaborate further. Like the above, this is justified since she's focused on getting Eggman out of Cyber Space, and she ends up teaming up with Sonic to take down The END at the end of the game]].
573* TheUnreveal: While the origins of [[spoiler:the Chaos Emeralds]] are revealed in the game, the nature of [[spoiler:the Master Emerald, which is shown to have already existed on Earth and in fact directed the Ancients and the Emeralds to the planet]], is left up in the air.
574* UnwittingInstigatorOfDoom: Sage and, by extension, Sonic. Sonic doesn't realize he's [[spoiler:freeing THE END]] by taking down the Titans. Sage ''does'', but since she's an Eggman construct given physical form, she's duty-bound to withhold ''all'' vital information from Eggman's arch-nemesis.
575* UseTheirOwnWeaponAgainstThem:
576** The boss fight against KNIGHT ends with Sonic finishing it off with its own {{BFS}}.
577** In "The Final Horizon", [[spoiler:Super Sonic steals the THE END-possessed SUPREME's rifle for Eggman to use, as the duo have Eggman fire a full cyber corruption-powered Super Sonic into THE END to take them down.]]
578* TheVeryDefinitelyFinalDungeon:
579** In the base game, [[spoiler:Ouranos Island]] is the last island with several challenges, Cyber Space levels, Guardians, and other things to find, and is home to [[spoiler:the secret fourth titan SUPREME and the battle against THE END]].
580** Since ''Another Story'' takes place entirely on [[spoiler:Ouranos Island]], the final dungeon is instead the last Tower of the Masters, [[spoiler:the secret fifth one specifically]], which must be scaled like the other towers through its platforming challenges to reach the top. Awaiting there is the final Trial, [[spoiler:a BossRush against the first three Titans]], and after beating it Sonic can fight the final boss of the update.
581* VideoGameDelegationPenalty: There is a fairly large combat moveset that Sonic can pull off with various button combinations. However, one unlockable upgrade allows him to mix up any number of moves by just tapping the attack button repeatedly. The game makes note that damage output is lower this way than actually doing the combos.
582* VillainRespect: After hearing one of Sage's reports, Eggman admits that Sonic escaping Cyber Space all on his own is very impressive. When Sage asks how he can say things like that in between cursing Sonic, Eggman clarifies that he hates the hedgehog, but is willing to admit when something about him is praiseworthy, despite that. One of his audio logs similarly has him saying he's "man enough to admit" that Sonic's ability to reach Mach 1 unaided is impressive.
583* VocalEvolution:
584** Creator/RogerCraigSmith sounds noticeably deeper in this game compared to his performance as Sonic in previous games. His normal inflections do crop up when he's snarky or bewildered, though.
585** As seen in ''Prologue: Divergence'', Creator/DaveBMitchell's performance as Knuckles is more reserved in comparison to his impression of Creator/TravisWillingham's performance from ''VideoGame/TeamSonicRacing''. It ends up sounding similar to Creator/RyanDrummond and Scott Dreier's takes on the character from the ''Adventure'' era, giving the character a stern, yet somewhat laid-back tone.
586** This also applies as well for Tails and Amy. Tails' voice is a bit deeper compared to his previous appearances, whereas Amy's is more reserved and less high-pitched, being somewhat on par with how she sounds moreso in ''VideoGame/SonicBoom'' and ''VideoGame/SonicForces''.
587** Dr. Eggman undergoes this as well. He still retains his more humorous, LargeHam tendencies but also shows a much wider range of expressions which haven't been seen since as far back as ''Adventure 1'' and ''Adventure 2'', even sometimes reaching into ''Sonic '06''. The result is a performance from Creator/MikePollock that is perhaps one of the most nuanced portrayals of the doctor in the series, one that can be seen as a perfect balance between how he portrayed the character during the Creator/FourKidsEntertainment era and the more recent games, even calling Deem Bristow's original performance from ''Adventure 2'' to mind at times.
588** In the Italian dub, Creator/MaurizioMerluzzo's performance as Knuckles sounds way deeper than in previous games, sounding more how he voiced his live-action counterpart in ''Film/SonicTheHedgehog22022''.
589* VoiceWithAnInternetConnection: Sonic is led away from danger by a disembodied voice from the sky itself with an electronic tinge. It tells Sonic how to save his friends: by retrieving the Chaos Emeralds and defeating the Titans. [[spoiler:This one has far more malevolent intentions, however, as it's the [[SealedEvilInACan sealed THE END]] intending to trick Sonic into freeing it.]]
590* WelcomeToCorneria: Every time you come to the menu for the fishing mini-game, you have to listen to Big say "Would you like to try? I'll let you borrow a rod", even if you return to it from the fish-o-pedia, the trade tokens section, or even after you're done fishing.
591* WhamEpisode:
592** ''Prologue: Divergence'' shows how Knuckles ended up on the Starfall Islands, revealing that there is a lost Cyber Space Portal in Sky Sanctuary. This implies that [[spoiler:the Ancients of the Starfall Islands have a link to Angel Island, the Echidna civilization, and the Emeralds]].
593** The game itself would elaborate further on this, [[spoiler:confirming that the Chaos Emeralds originated from outer space and belonged to the Ancients. It's also confirmed through Eggman's Egg Memos that Chaos and the Chao are descendants of the Ancients.]]
594** Rhea Island, the game's penultimate zone, [[spoiler:finally reveals the fate of the Ancients, sees Sonic fully corrupted by the effects of Cyber Space, and concludes with THE END breaking free of its seal and revealing its true colors]].
595* WhamLine: This line at the conclusion of Rhea Island, revealing Sage's true motives and the identity of Sonic's mysterious guide.
596-->'''[[spoiler:THE END]]:''' [[spoiler:[[AncientEvil Since time immemorial]] I have languished here. The locks are broken. Now I shall tear down the walls between dimensions '''[[OmnicidalManiac and consume all]]'''.]]
597* WhamShot: The teaser trailer for "The Final Horizon" has Sonic using the Chaos Emeralds to become Super Sonic when faced with SUPREME...and then he unleashes a burst of what looks like cyber corruption, resulting in him being surrounded by a dark red aura, which then clears to reveal that Sonic's eyes have turned cyan. That's right, Sonic's GoldenSuperMode is now even more super!
598* WhatHappenedToTheMouse: Big's presence in the game is not explained and he is not rescued alongside the rest of Sonic's friends by the end of the game. Sage gets around to clarifying this in ''Another Story'' by positing that Big wasn't actually in Cyber Space and was simply recreated from Sonic's memories of him.
599* WholePlotReference: DoubleSubverted: the plot bares more than a passing resemblance to ''VideoGame/TheLegendOfZeldaBreathOfTheWild'': Sonic explores a wide open land long after its fallen into ruin. Get occasional flashbacks into the past. Is guided by a feminine voice. Collects cute little creatures for upgrades. The game involves fighting giant machines. His closest friends are now phantoms (in this case trapped in an alternative reality rather than ghosts). And the world has occasional big in-game event that resets the game's items and monsters. And the world is dotted with minor puzzles that slowly increase Sonic's strength. However, it flies off the rails and reveals it's actually got more in common with [[spoiler:''VideoGame/ShadowOfTheColossus'']] instead: In order to save loved ones, Sonic has to take down gigantic creatures [[spoiler:that turn out to be the [[SealedEvilInACan seal for the setting's villain]] and each victory further and further corrupts him.]]
600* WideOpenSandbox: The developers prefer the term "open zone"; rather than one expansive overworld, the game consists of a handful of regions that aren't connected to each other, but are self-contained sandboxes in themselves.
601* TheWorfEffect:
602** Sonic's first confrontation with GIGANTO results in him being thrown a sizable distance across Kronos Island [[CurbStompBattle before he can even land a dent on the colossal enemy]], and it's only when he manages to become Super Sonic that he's able to do any kind of damage. [[spoiler:After defeating GIGANTO, however, ''something'' (soon revealed to be ancient laser cannons) in the next island attacks Sonic with enough power to actually ''knock the "Super" out of him'', scattering the Chaos Emeralds in the process, and forcing him to get them again, and this happens a couple more times. The fact that the Chaos Emeralds' power are tied to Starfall Islands may have something to do with negating Sonic's.]]
603** Knuckles also finds himself on the receiving end of this effect in the ''Prologue: Divergence'': after handily beating a group of minor enemies, Knuckles finds himself confronted by Sage and not a Titan, but an ASURA, one of the Guardians. One FadeToWhite later, he finds himself a prisoner on the Starfall Islands.
604* WritingAroundTrademarks: The game includes [[https://twitter.com/sonic_hedgehog/status/1583126046164930560 the Soap shoes]] from ''VideoGame/SonicAdventure2'' as an incentive to sign up for the online newsletter; however, the shoes are exclusively referred to as "the shoes from ''Sonic Adventure 2''" as opposed to any brand name. As the Soap company is long gone, Sega can use the design, but not the name.[[note]]The shoes were originally referred to as the "2G Hi-Speed Shoes" by the company in the past.[[/note]]
605* YouAreNotReady: Said verbatim by Sonic's VoiceWithAnInternetConnection if he tries to activate something without the requisite amount of collectibles or story progress.
606-->''You are not ready. Return when the time is right.''
607* YouCanBarelyStand: A non-malicious example, [[spoiler:while Sonic attempts to shut down the towers on Rhea Island, his Cyber Corruption starts to overtake him, to the point he struggles to walk (in the cutscenes at least). Sage, in bewilderment, asks how he can still smile in the face of adversity despite him being barely able to stand up. Sonic can only give a confident smile as he continues walking, with Sage later coming to the realization his HeroicWillpower allows him to keep pushing forward in order to protect those he cares about]].
