Video Game: Sonic the Hedgehog 2

An attitude, tons of enemies, and a running mate with the mind of a four year old. (No, it's not another presidential election).

The sequel of the original Sonic the Hedgehog, and proof that Sega's little blue mascot wouldn't be going away anytime soon.

This game is notable for introducing Sonic's buddy Tails, Super Sonic (the eponymous character's Emerald-powered super form), and the Spin Dash technique — all of which have become series staples. It is the second best selling Sega Genesis game of all time, selling over six million copies, only outsold by it's predecessor's 20,000,000 mark.note 

Like its predecessor, Sonic the Hedgehog 2 had both a 16-bit and 8-bit version, but unlike its predecessor, both versions had different stories.


The 16-bit version

Released for the Sega Mega Drive/Genesis worldwide Tuesday, November 24, 1992, a date nicknamed "Sonic 2sday" during its marketing campaign.

While out on adventure, Sonic landed his biplane, the Tornado, on the dainty and pleasant Westside Island to take a break. While there, Sonic meets a shy fox cub named Miles Prower, called "Tails" by the animal inhabitants of the island due to the fact that he has two tails. Sonic allows Tails to tag along with him, and surprisingly the fox can keep up with him by rotating his two tails like a propeller. Tails also have a young interest in machinery, as evident when he excitedly examines the Tornado while Sonic is napping.

Meanwhile, Dr. Eggman (also known as Dr. Ivo Robotnik), still smarting from his defeat on South Island, has gone global: he followed Sonic and started operations on the other side of the island, managing to covertly produce a new generation of Badniks. While there, he is also privy to the legends that tell of a seventh lost Chaos Emerald that belonged to a previous civilization — and quickly realizes that the other Chaos Emeralds that scattered are also resting within the island's depths. Making his move to grab the island's resources, he hopes to complete his weaponized space station, the Death Egg. It's up to Sonic to stop him, but he's going to need help... and a vulpine pilot to make the Kessel run in less than twelve parsecs.

Sonic the Hedgehog 2 kicks everything up a notch. The gameplay is faster than its predecessor. It features 11 Zones, most of which have two Acts; to compensate for having one Act less per Zone than its predecessor, the Acts here are quite a bit longer. Debuting here is the Spin Dash, a technique where Sonic (or Tails) spins in place, revs up, and takes off as a spinning ball of doom, allowing players to destroy Badniks without having to jump and gain instant speed to go up slopes and loops. Also making its debut is the super form; here, after collecting all seven Chaos Emeralds and gathering 50 rings, Sonic turns into Super Sonic, a golden hedgehog who's even faster than his regular form and possesses a higher jump (as well as invulnerability). The Special Stages were also retooled, introducing a "non-stop 3D movement" philosophy that would be embraced by the Special stages of its successors. Thanks to these improvements and additions, Sonic the Hedgehog 2 is a massive fan favorite, not to mention the second-best-selling Genesis game of all time (right behind its predecessor, of course). To this day, critics often hail it as one of the best games in the franchise.

The game is the first part in a three game arc regarding the Death Egg, being resolved in the bipartite game, Sonic 3 & Knuckles.

In 2013, off the heels of the similarly remade Sonic CD and Sonic the Hedgehog, Sonic the Hedgehog 2 (and, by extension, Knuckles the Echidna in Sonic the Hedgehog 2) was remade in the Retro Engine by Christian "The Taxman" Whitehead and Simon "Stealth" Thomley. This time, Sonic and Tails's team-up ability returns and Tails now has the ability to fly and swim, something that he was unable to do by himself in the original version. The remake also adds a new Boss Attack Zone and Hidden Palace Zone. The two-player mode also underwent a major upgrade. Chemical Plant Zone, Aquatic Ruin Zone, Hill Top Zone, and Oil Ocean Zone are now available, Knuckles is no longer confined to the single-player experience, both players can be the same character competitively, and each player's screen occupies their own device (rather than appearing in a split-screen as in the original).


Tropes appearing in this version:

  • Acrofatic: Dr. Eggman turns out to be this when fleeing Sonic into the Death Egg Robot. How he outruns Sonic is unclear.
  • Action Bomb: Telstars/Asterons.
  • Airborne Aircraft Carrier: Wing Fortress Zone.
  • Airborne Mook: Stinger/Buzzer (based off the previous game's Buzz Bomber), Bun Bun/Whisp, Flasher, Seadra/Aquis, and everything in the Sky Chase Zone.
  • All In The Manual: Japanese strategy guides provide names for all the boss machines, including Mecha Sonic.
  • Art Evolution: The early version of the Casino Night Zone looks kinda different.
  • Artificial Stupidity: Tails without a second player. To the point where on certain levels, he can spend more time dead than alive despite being invulnerable to enemies.
  • Ascended Meme: The infamous spike pit in Mystic Cave Zone Act 2 is where you access Hidden Palace Zone in the iOS and Android remakes.
  • Batman Can Breathe in Space: As indicated by the end of Wing Fortress Zone, both Sonic and Tails can breathe in space, but not in water.
  • Big Damn Heroes: Tails gets such a moment in the normal ending by flying the Tornado to catch Sonic in the sky after the Death Egg's explosion. If playing as Tails alone, Sonic gets this moment instead. If all seven Emeralds are collected as Sonic, he goes Super after leaving the Death Egg and flies alongside the Tornado instead.
  • Bonus Boss: Featured in the remake's Hidden Palace Zone, in place of the Mystic Cave Zone boss during gameplay.
  • Bonus Feature Failure: Tails is identical to Sonic in every way, with one exception: unlike Sonic, he cannot go Super (the player couldn't actually control his signature flying ability while playing as him until Sonic Chaos and slightly later in 16-bit in Sonic the Hedgehog 3, and he also had a lowered jump height and running speed). The iOS/Android version averts it by including Tails's flight, but it can be turned off via cheat.
  • Bonus Stage Collectables: The Chaos Emeralds are back, and they are collected the same way as before (enter and complete Special Stages). This time, however, there are seven of them, and to access the Special Stages, you now have to pass a check point with 50 rings and enter the portal above it.
  • Butt Monkey: Tails is, as one "Let's Play" author on YouTube put it, gaming's first meat shield.
    • Iron Butt Monkey: That said, the kid can shrug off anything, rotoring his way back into the action even if he was just killed seconds before.
  • Canon Immigrant: The "Grey Emerald" was a unique Chaos Emerald in the older promotional comics (which was reused as the backstory in certain materials such as Sonic the Comic). The newly uncovered Chaos Emerald is a similar color.
  • Casino Park: Casino Night Zone.
  • Character Select Forcing: Downplayed, but when playing alone, the default "Sonic and Tails" option is a little more difficult than playing either of them alone. In the Special Stages, you need more rings to succeed, and the computer Tails is very unlikely to make up the difference. It's also possible to put Tails in front in these stages, which is not good. Outside of Special Stages, Tails is liable to hit Eggman at the worst possible time, causing Sonic to go through him, which is particularly deadly in the Chemical Plant Zone encounter. Also, Tails Alone isn't quite as good as Sonic Alone in the original version, since he doesn't have a super form and doesn't have the flying ability to make up for it.
  • Collapsing Ceiling Boss: The fight with Eggman at the end of Mystic Cave Zone. The trick is to avoid only the sharp spikes, as the round rocks are completely harmless.
  • Comic Book Adaptation:
    • Issues 228 and 229 of Archie Comics' Sonic the Hedgehog feature Sonic and Tails, along with Sally, Antoine, and Rotor, traveling through some of the game's levels.
    • Also, issue 6 of Sonic the Comic had a story in which Sonic and Tails travel through the last two zones of the game in order to prevent the destroyed Death Egg from crashing into the Emerald Hill Zone.
    • Averted in Sonic the Comic and the newer Archie comics, which began too late to do a proper adaptation; instead, when they need to refer to the game's events, they simply tell readers to play the game for themselves (meaning it takes place in both the game only, Fleetway Editions, and Archie Comics continuities).
  • Continuing Is Painful: This game is an example in which continuing after something beneficial happens can be painful: once you go into a Special Stage, you come back out with no rings. Thankfully, this isn't the case when playing as Knuckles in the original version of Knuckles in Sonic 2. In the remake, however, Knuckles also loses all of the rings when he comes out of a Special Stage
  • Cool Plane: The Tornado. It even gains a rocket booster in the finale.
  • Co-Op Multiplayer: Of the tag-along variety; in single player, a second player can control Tails. However, his flight ability can only be used when AI controlled. There is versus mode multiplayer as well.
  • Credits Medley: The credits music plays a medley of all the themes you heard in each Zone.
  • Crosshair Aware: A cross-hair follows Sonic around during the Final Boss fight when it jumps into the air and tries to land on him.
  • Cut Song: Track 10 in the game's sound test is an unused and hauntingly good song that was originally meant for Hidden Palace Zone, and ended up unused when the Zone itself was Dummied Out. Even when Hidden Palace Zone returned in the 2013 remake, the song remained unused (the version uses the 2 Player Mystic Cave Zone theme, which is what it used in leaked prototypes).
  • Disney Owns This Trope: Sega holds patents for the corkscrews from Emerald Hill, the loops from Aquatic Ruin which are crossed by an alternate path and also the teleportation item from Vs. mode.
  • Do Well, but Not Perfect: The infamous spike pit in Mystic Cave Zone Act 2 is only really a problem for Super Sonic (and speedrunners). Regular Sonic's jump arc will automatically snag a switch that lowers a drawbridge, while Super Sonic has a bad tendency to swoop through the air too fast and miss it.
  • Drought Level of Doom: Death Egg Zone. Very Definitely Final Dungeon. One midboss and the Final Boss. No rings.
  • Dub Induced Plothole: The North American and European manuals have a different account of Tails, stating that he was an intense fan of Sonic's for as long as he can remember and imply that the game takes place on the same island as the first, which is incompatible with pretty much every later depiction which sides with the original Japanese storyline of how they first met. This pretty much single-handedly generated the entire concept of "SegaSonic" in the late '90s/early 2000s fandom. Interestingly, the storyline information presented in the 2013 mobile version tries to merge both.
  • Dub Name Change: The main antagonist and virtually all the robots were once again renamed in localization, and this time, the Japanese version was barely released first; unlike the first game, however, "EGGMAN-01" is written on Wing Fortress, and there is a mildly recurring "EG" symbol (replaced with an emblem of his head later in the series).
  • Duel Boss: The battles at the Wing Fortress and Death Egg Zones, since even in Sonic & Tails mode, Tails is shot down in the Tornado on the way there.
  • Dummied Out: A couple of Zones met this fate, most notably the Hidden Palace Zone, of which you can find its rather somber BGM (track 10) in the final version. Hidden Palace Zone finally appears Sonic & Knuckles. However, the Sonic & Knuckles version of Hidden Palace looks completely different. The planned Zone was reimagined on the iOS and Android versions as part of a December 2013 update, although the 2P Mystic Cave Zone music plays instead.
  • Eternal Engine: A number of Zones, but most notably Chemical Plant Zone and Metropolis Zone.
  • Everything Trying to Kill You: Mystic Cave Zone and Metropolis Zone.
  • Evil Overlooker: Dr. Eggman in the (now-iconic) European/North American poster and box art.
  • Gameplay and Story Segregation: If you're playing as Sonic and Tails, both characters are present in the Special Stages even during Wing Fortress Zone, where Tails is absent.
  • Game-Breaking Bug:
    • Whatever you do, do not try to turn back into Super Sonic again at the end of a level (where touching a Goal Plate or Capsule cancels out Super Sonic automatically); most of the time, doing so will trap Sonic in mid-air, preventing the game from moving on to the next level, and thus forcing the player to reset the game. It should be noted that is only applies to the first versions of the game. A later revision released on the Sonic Classics cartridge fixed this glitch.
    • Turning into Super Sonic while you complete the Wing Fortress level will leave you unable to finish the level. Super Sonic jumps too high and this causes him to miss the scripted event of Tails's plane flying below to catch him, which in turn causes you to plummet to your death and replay the battle or level again.
  • Green Hill Zone: Emerald Hill Zone, essentially an easier variation on the original Green Hill Zone.
  • Golden Ending: The 2013 remake one ups the original ending: Get all seven Emeralds and, at the credits, you'll watch the Death Egg crash on a certain island and, as Eggman stomps his feet in front of his wrecked mecha, a certain guardian's eyes peek out of the bushes.
  • Hailfire Peaks: Several Zones don't fit well into any one category, such as Hill Top Zone (Death Mountain / Green Hill Zone / Lethal Lava Land) and Aquatic Ruin Zone (Temple of Doom / halfhearted Under the Sea). Casino Night Zone is one part Casino Park and one part Pinball Zone.
  • Human Cannonball: One of the more fun ways of getting around Oil Ocean Zone is to shoot yourself out of the various cannons dotted throughout the level.
  • Humongous Mecha: The Death Egg Robot (as named in Sonic Generations).
  • 100% Completion: The "perfect bonus", awarded for picking up (not necessarily retaining) all the rings in an Act. It's not possible in every Act.
  • Inconveniently Placed Conveyor Belt: Metropolis Zone has quite a few.
  • Impossibly Graceful Giant: Averted by the Death Egg Robot, who moves rather slowly. Made ironic by Dr. Eggman's running skills shown before the battle.
  • Invincible Minor Minion:
    • Guardon/Crawl in the Casino Night Zone can only be destroyed by spinning or rolling into him from behind: attacks from above or the front bounce harmlessly off its pinball bumper shield. On the other hand, it's fairly passive and if you don't bother it, it won't bother you. An appropriate enemy for the Casino Park level.
    • The Flashers in the Mystic Cave Zone are invincible when lit up (even when Sonic himself has the invincibility power-up, he'll just pass straight through them without destroying them).
  • Kaizo Trap:
    • Sort of. During the boss fight in Chemical Plant Zone Act 2, the ground on either side of the arena flips periodically, sending whatever's on them into the water and the pit just beneath the surface. Since there's probably no hope for you if you fall in, you still have to be careful after the boss is beaten, because the platforms still flip. It doesn't help that said boss is suddenly harder than what little you've already gone through.
    • A literal kaizo trap can happen at the end of Metropolis Zone Act 3. If you beat the boss as Super Sonic without destroying any of the clone bubbles the boss spawns and then run out of rings before reaching the animal pod at the end of the level, it's actually possible for the clone bubbles to follow you over to the pod and kill you while your end-of-level score is being tallied. Of course, you'd pretty much have to be actively trying for this to happen, so it overlaps heavily with Epic Fail.
  • Levels Take Flight: The aptly named Sky Chase Zone. Despite the mellow groovy background music, and relaxed pace, it's harder than it looks.
  • Logo Joke: Sonic rushes to the right, and then to the left, his after-image revealing the Sega logo, the "SAYYYYYYY-GUH!" from the first game then playing.
  • Long Song, Short Scene: The Death Egg Zone theme is whimsically creepy, catchy, and awesome. However, since it's only played in the corridor before the Mecha Sonic fight, you likely won't even hear 10 seconds of it. This is justified by the fact that it was originally supposed to be played for a full-length Act in the Death Egg Zone, but that was Dummied Out.
  • The Missingno.: Messing around in Debug Mode could turn Sonic's sprite black and green; fans have nicknamed this new "character" Ashura.
  • Mordor: Oil Ocean Zone is a Type 2.
  • Mythology Gag: The 2013 remake adds a green Handrill/Grounder into the Debug Mode for Aquatic Ruin Zone.
  • Non-Lethal Bottomless Pits: That infamous spike pit in Mystic Cave Zone Act 2 leads to Hidden Palace Zone in the remake.
  • Not-So-Harmless Villain:
    • The crab-themed Badniks in every other Sonic game, and most relevantly the Crabmeats in the first game, are usually The Goomba, among the weakest enemies. Then the Metropolis Zone throws the Kani Punch/Shellcraker[sic] at you, which looks similar but is insanely hard to avoid or kill with an incredibly small hitbox.
    • The Guardon/Crawl in Casino Night Zone are impossible to defeat from the front or the top because they always block your moves. You have to spin dash them from behind. This has caught a lot of players out.
  • Old Save Bonus: If the game is locked on with Sonic & Knuckles, Knuckles in Sonic 2 can be played. This makes Knuckles playable with all his abilities from Sonic & Knuckles intact. In the 2013 remake, Knuckles is available from the beginning.
  • One-Hit-Point Wonder: With no rings available in the final stage, Sonic is effectively reduced to this.
  • Oxygenated Underwater Bubbles: Present throughout Aquatic Ruin Zone.
  • Palette Swap:
    • Tails is basically this for Sonic. Despite being able to fly while AI-controlled, you can't do so while playing as him. The only major gameplay difference is that Tails can't go super. This was addressed in Sonic 3.
    • Also, Hill Top Zone uses almost the same graphics as Emerald Hill Zone. The only differences being that the ground has blue blocks under the grass instead of brown, it has lava, and it has pine trees instead of palm trees. Loading the game in a tile editor reveals Emerald Hill Zone even has the vines that those blue platforms slide down, and a very early prototype of the game (which appears to be the same one shown on an episode of Nick Arcade) allows you to place the seesaws from Hill Top in Emerald Hill by using Debug Mode.
    • Emerald Hill Zone and Hill Top Zone were the first two levels designed for the game, and it's not inconceivable that they were supposed to follow one another at one point. The unfinished Dust Hill/Sabaku/Desert Zone was also supposed to have a winter version literally known as Winter Zone in concept, but this was never implemented into the game. The game developers said they used the same palette to save space, the same reason why the first game used Labyrinth Zone's Palette for Act 3 of Scrap Brain Zone.
    • It's harder to notice, but the Death Egg Zone uses the same tileset as the Chemical Plant Zone.
    • In Knuckles in Sonic 2, the blue background of the zone title cards is green, the Shield is gray instead of blue, and the Flickies are red. None of these color changes are present in the iOS/Android remake of the game.
  • Pinball Zone: Casino Night Zone, and even the boss is this,
  • Pop-Star Composer: Dreams Come True bassist Masato Nakamura once again, who provided music for its predecessor. Due to financial disagreements between him and Sega, this would be Nakamura's last contribution to the series until Sonic 2006 (where Dreams Come True teamed up with Akon to do a remix of "SWEET SWEET SWEET" and "SWEET DREAMS"). Nakamura's departure resulted in the intro music for Sonic Spinball, originally a metal-esque remix of his Sonic theme, getting replaced by a different tune in replacement copies, and Sega relying on composers from its Wave Master music studio to write the music for most subsequent Sonic games.
  • Puzzle Boss: The boss of Hidden Palace Zone, where Eggman's mobile flies out of reach. You need to wait for Eggman to summon a large Sea Mine, then lure him over it when it explodes into a water column that knocks him down for a while, allowing Sonic to hit him.
  • Scenery Porn: The second game manages to be even more beautiful than the first, which was already gorgeous as it was.
  • Schizophrenic Difficulty: Chemical Plant Zone Act 2 is a lot harder than its position in the game (fourth Act out of twenty) would suggest, and for a while afterwards the game gets quite a bit easier.
  • Secret Level:
    • The 2013 remake adds one. In the original version, there is an inescapable spike pit in Mystic Cave Zone Act 2. The remake removes the spikes and the pit instead leads to none other than the formerly Dummied Out Hidden Palace Zone. Furthermore, the "Simon Wai" version of the level, with the probably intended sad music, is accessible by a code.
    • The remake also has a hidden Special Stage that can be played through the level select menu. It has corkscrews near the end!
  • Sequel Hook: Present in the remake once you've collected all the Chaos Emeralds.
  • Shoo Out the Clowns:
    • When playing as Sonic with Tails tagging along, the Tornado gets shot down at the beginning of Wing Fortress Zone, with Tails inside. Sonic has to face the last two Zones alone.
    • Inverted if you're playing as Tails: the Tornado gets shot down with Sonic inside.
  • Shout-Out:
    • Few American kids might have caught the reference in '92, but looking back, it's hard to observe Sonic powering up to an absurdly high level by sporting gold fur and wildly upright spines (after collecting seven artifacts of power, no less) and not be reminded of a certain manga/anime series. Also, that's no moon.
    • In another anime reference that no American kids at the time would have gotten, the final boss highly resembles a Scopedog from Armored Trooper VOTOMS, modified to look like Eggman.
    • Not even the cheat codes are immune to this. Due to every sound in the Sound Test being assigned a hexadecimal number, it wasn't difficult for Sega to slip in a couple of extra shoutouts. Using the Japanese date format (year, month, day), the level select code becomes September 17, 1965 (19-65-09-17) - Yuji Naka's date of birth - while the debug mode code becomes November 24, 1992 (01-09-09-02-01-01-02-04); the fabled "Sonic 2sday" that saw the game's North American and European release.
  • Smashing Hallway Traps of Doom: Mystic Cave Zone and Metropolis Zone have most of them in this game.
  • Spell My Name with an "S": It's Westside Island or West Side Island, depending on who you ask.
  • Spikes of Doom: Many of them. The most notable one is the inescapable spike pit in Mystic Cave Zone Act 2, which could kill you even if you're Super Sonic by making you wait until you lost all your rings, revert back to normal Sonic, and die. Said spike pit was replaced by the entrance to the Hidden Palace Zone in the 2013 remake.
  • Spiritual Successor: Several levels follow the same themes as those in the first game.
    • The Emerald Hill Zone for the Green Hill Zone.
    • The Casino Night Zone is a development on the Spring Yard Zone "pinball machine" theme, to the extent that it's one of the most influential levels on future Sonic games while all vestiges of Spring Yard were dropped.
    • The Metropolis Zone for the Scrap Brain Zone. Both are an Eternal Engine, green in color, etc. To the point where people playing Sonic the Hedgehog 2 for the first time in 1992 were subject to Your Princess Is in Another Castle when they found out it wasn't in fact the final Zone.
    • Aquatic Ruin Zone is this for Labyrinth Zone, due to its use of water and ruins, but is somewhat easier.
  • Spoiled by the Manual: Although the English manual stops the level description list at Wing Fortress, it reveals the Final Boss on page 4.
  • Soundtrack Dissonance: Despite song hexadecimal 10 commonly referred as Hidden Palace's theme, it is not included in the iOS/Android version, due to the fact that the producers felt the song couldn't fit the pace or prehistoric feel of the recreated level.
  • The Stinger: The remake has an additional ending cutscene for getting all the Chaos Emeralds, which hints at a remake for the final 16-bit Sonic game(s).
  • Super Mode: Introduced in this game. Become Super Sonic by collecting all Chaos Emeralds. After that, collect 50 rings and jump. Normally touching enemies hurts Sonic, but as Super Sonic, it defeats enemies instead. Touching spikes in Super Mode won't hurt Sonic either, but he can still die by falling in a bottomless pit, being crushed, or drowning. As Super Sonic, Sonic's rings decrease steadily and he turns back into regular Sonic if he runs out. It's only for Sonic though. Tails will have to wait for the next game(s).
  • Tagalong Kid: Sonic's new sidekick Tails.
  • Theme Music Power-Up: Super Sonic.
  • This Is a Drill:
    • Eggman has two drill-themed contraptions: the drill-tank contraption from Emerald Hill Zone, and the cave-burrowing contraption from Mystic Cave Zone.
    • The Handrill/Grounder Badnik in Aquatic Ruin Zone has two drills for hands and a third for a nose. The Tsun Tsun/Spiker Badnik in Hill Top Zone comes equipped with a detachable spiked drill on its head.
  • Tube Travel: In the Chemical Plant Zone and the Metropolis Zone.
  • Under the Sea: Aquatic Ruin Zone is a fairly halfhearted attempt, given that it's quite easy to pass both Acts without going underwater once. It may represent fan backlash over Labyrinth Zone, but annoyed players who didn't automatically view water levels as Down the Drain. Ironically, you could easily spend more time underwater in the Chemical Plant Zone.
  • Unwinnable by Mistake: When you finish the stage as Super Sonic (i.e. run past the spinning sign at the end), you immediately power down. If you jump again, you'll transform into Super Sonic, immediately power down, and be stuck running in place in mid-air. Sonic runs to the right and offscreen when the sign finishes spinning; but if he's stuck in mid-air, the stage doesn't register as finished and you have to reset.
  • Video Game Cruelty Potential:
    • Tails may be immortal, but the level design offers ample opportunity to "kill" him by squashing him with obstacles. This potential became a Running Gag in Cybershell's Let's Play of this game and Sonic 3 & Knuckles in retaliation for Tails's Artificial Stupidity.
    • This is also the entire point of the Tails abuse Machinima series by Whoisthisgit on YouTube (the ones that use actual gameplay at least).
  • Wake-Up Call Boss: Eggman's chemical-dumper contraption from Chemical Plant Zone, the second Zone. It's not too hard, but the two platforms on both sides of the field periodically collapse into bottomless pits, making it very possible for a chemical projectile to knock you into the pink water ("Mega Mack") below. Playing as "Sonic and Tails" also presents its share of problems, as when you jump, so does Tails, and if he hits Eggman first, you'll go through Eggman (due to his Mercy Invincibility) and down the pit. However, if you actually have a second player to wield the other controller, it becomes laughably easy, since a crouching Sonic is immune to the boss' attack, and Tails will always respawn if you manage to get him killed.
  • Warmup Boss: The Egg Mobile-D (Egg Mobile Drill Machine) from Emerald Hill Zone, which goes from one side of the screen to the other. It's even easier than the wrecking ball contraption from Green Hill Zone (which was also the first boss of its respective game).
  • Would Be Rude to Say "Genocide": Genocide City was one of the working titles another Zone, along with Cyber City. The Japanese developers initially chose the name because they thought it sounded cool and daring. The layout ended up being used as the third Act of Metropolis Zone, and the leftover designs were used as the aesthetic of "The Machine" in Sonic the Hedgehog Spinball.
  • Wrap Around: A few parts in Metropolis Zone loop vertically, leading to instances of I Fell for Hours.

The 8-bit version

Released for the Sega Master System and Game Gear, this version was actually the first to be released and thus Tails' official debut, although the Mega Drive backstory is his formal introduction. It was anonymously developed by a game company called Aspect.

Bored after defeating Dr. Ivo Robotnik a little while back, Sonic leaves South Island in search of adventure. When he returns, he finds all of his animal friends are missing from the island. Puzzled, he returns to his "digs" to find a letter from his pal Tails, which states that Robotnik is behind the kidnappings, and he's keeping Tails at a place called the Crystal Egg Zone, which requires the six Chaos Emeralds to reach. Justifiably riled up, Sonic sets off once again to take down Robotnik.

This version of Sonic the Hedgehog 2 builds on its predecessor with somewhat faster gameplay, even including loops in two Zones. It also includes some differences from its 16-bit counterpart, such as Zone gimmicks including mine carts and hang gliders, the lack of a spin dash (perhaps due to being this being the first version released), and the omission of Tails as a playable character (for obvious reasons, of course).

Once again, however, the Emeralds are collected in the second act of each Zone, except for the sixth, where it's the reward for beating the penultimate Zone's boss after collecting the first five. Getting all of them grants access to the true final Zone, the aforementioned Crystal Egg, where Sonic confronts Robotnik in a final battle to save Tails.

It's also the only SMS/GG Sonic game to not have Special Stages.


Tropes appearing in this version:

  • Antlion Monster: The first boss is a robotic antlion. To defeat it, Sonic must dodge the cannonballs that Robotnik throws at him so that they will hit the robotic antlion. Eventually, Robotnik flies down at Sonic and Sonic must dodge him as well so Robotnik will inadvertently deliver the final hit. This boss is harder in the Game Gear version due to the reduced amount of space on the screen.
  • Bond Villain Stupidity: The sequence before the first boss battle can look like this: if Robotnik wants Sonic dead, why did he rescue him at the end of the Underground Zone? To drop him in front of his death trap, of course... but if one remembers the plot of the game, Robotnik wants the Chaos Emeralds. At this point of the game, Sonic is supposed to already have one Chaos Emerald out of six, and Robotnik sure doesn't want it to sink into the lava.
  • Boss-Only Level: Act 3 of every Zone has no enemies, only some platforming and then the boss. There are also no rings in Act 3.
  • Bright Is Not Good / Crap Saccharine World: Crystal Egg Zone, the true final zone of the game, is oddly bright colored and cheerful, with happy music. It is also the inner sanctum of Robotnik, and while the zone is fairly easy the boss isn't.
  • Bubbly Clouds: Sky High Zone is a mix of this and Death Mountain, as the lower parts of its Acts appear to be a mountain peak and the upper parts are clouds, some of which can be stood on.
  • Camera Screw: One of the reasons that the Game Gear version is considered Nintendo Hard.
  • Easter Egg: There is a 1-up hidden at the left side of Sky High Zone Act 1. When Sonic jumps over the monitor, a group of birds will come out of the trees and jump around.
  • Floating in a Bubble: There are giant bubbles in the second act of Aqua Lake Zone, which Sonic can float in.
  • Green Hill Zone: Green Hills Zone.
  • Hostage for MacGuffin: Tails.
  • Kill the Cutie: Heavily implied in the Downer Ending.
  • Never Trust a Level Intro: Each level intro segment features Sonic and Tails going through the trials of the upcoming level, but Tails is not a playable character; he is kidnapped.
  • Nintendo Hard: The Game Gear release is considered significantly harder than the Master System's due to a smaller resolution inhibiting players from being able to see what's ahead, resulting in cheap hits/deaths.
  • No Fair Cheating: You need all the Chaos Emeralds to get to the Crystal Egg Zone to get the good ending. If you don't have them all (save the one you get from the boss) the game ends there with the bad ending. If you use the level select cheat to get to the Crystal Egg Zone, you'll rescue Tails (he'll appear in the teleporter when Robotnik retreats), but he won't be there in the ending.
  • Plot Hole: If the storyline tells us that six Chaos Emeralds are needed to travel to the Crystal Egg... then how did Robotnik and Tails get there in the first place?
  • Sequel Difficulty Spike: Due in part to the lack of checkpoints or shields and the increased length of the still-ringless boss Acts (Green Hills Zone Act 3 in particular has a series of blind jumps over spike pits before you reach the boss), this game is generally regarded as significantly harder than its predecessor, as well as harder than most other Sonic games from the same era. The Game Gear version adds some difficulty due to the screen displaying a smaller area, but even the Master System version is widely considered difficult by the standards of the series.
  • Soundtrack Dissonance: In the Master System version, what is the cheery title screen music in the GG version plays in the opening cutscene where Tails is kidnapped by Robotnik, and the melancholic music from the bad ending plays for both endings. The Game Gear version rectifies both cases by using the suitably foreboding Scrambled Egg Zone theme in the opening cutscene and providing happy music for the good ending.
  • Stars Are Souls: During the staff roll credits of the bad ending, Sonic looks up into the sky and sees an image of Tails among the stars. This can be interpreted to mean that Robotnik actually killed him (although this interpretation doesn't explain why in the good ending Sonic and Tails are both pictured among the stars, while being alive and well).
  • Villainous Rescue: Robotnik surprisingly pulls this on Sonic in Underground Zone Act 3; when Sonic is about to fall into a pit of lava, he hastily grabs him with a claw machine, lifting him up...only to drop him into a boss battle.

Tropes appearing in both versions:

  • Eternal Engine: Metropolis Zone in the 16-bit version, Gimmick Mountain in the 8-bit version.
  • Evil Knockoff: The Silver Sonic/Mecha Sonic.
  • Green Hill Zone: Emerald Hill Zone and Green Hills Zone in the 16-bit and 8-bit versions respectively.
  • Multiple Endings: As mentioned above, the ending in the Mega Drive version changes a little based on who you're playing as and, in Sonic's case, whether or not you got all the Emeralds, though there are no downer endings or even stingers (though the latter was rectified in the 2013 remake). In the 8-bit version, without collecting the first five Emeralds upon defeating the Scrambled Egg Zone boss (Silver Sonic), the game simply ends there, and you get a total Downer Ending. Unable to save Tails, Sonic runs along a trail alone, and after the staff roll ends, he halts to look at the sky, where he sees Tails's face in the clouds. The good ending is infinitely more satisfying. Sonic and Tails run along a trail (with happier music, if playing the Game Gear version), and after the staff roll ends, they halt to look at the sky, and see each other's faces in the clouds.
  • Lethal Lava Land: Hill Top Zone and Metropolis Zone (Genesis), and Underground Zone (8-bit).
  • Punny Name: Miles Prower = "miles per hour".
  • Sequel Difficulty Spike: Both games are considerably tougher than the first game for Mega Drive and Master System, the Game Gear version of the sequel being particularly more brutal than the original.
  • Underground Level: Mystic Cave Zone (Genesis) the aptly named Underground Zone (8-bit).
  • Underwater Ruins: Aquatic Ruin Zone (Genesis) and Aqua Lake (8-bit).
  • Villain Exit Stage Left: In the Genesis version, Dr. Eggman flies away when defeated, as usual. However, when defeated on his giant mech, he goes down with the Death Egg (though as the all-emeralds ending added in 2013 remake shows, he survived and the Death Egg wasn't completely destroyed). In the 8-bit version, it's played straight as he escapes after the final battle.
