• Dead by Daylight
• Fall Guys
• Identity V
• Touhou Project

---

• 7.62 High Caliber has a mod named Blue Sun, which turns the native game in a cross-over with Jagged Alliance 2^note 7.62 High Caliber being the official sequel of Brigade E5: New Jagged Union, Creator-Driven Successor to the Jagged Alliance series: there are dialog lines mentionning the country Arulco (7.62 High Caliber being set in another Banana Republic suffering from a civil war), several dozen of mercenaries from the Jagged Alliance series can be hired, the weaponseller Bobby Ray can be contacted by radio, a sidequest involves Elliot who fled Arulco to escape from Deidrenna's constant brutality, etc.
• AdventureQuest Worlds has a crossover event with Ctrl+Alt+Del.
  • AdventureQuest Worlds itself is one huge mix of the three main AE games, AdventureQuest, DragonFable, and MechQuest. Heroes and villains from all three have been featured in the game, although arguably the most evil villain of all three gets killed off right in the beginning of the game.
  • Before that, DragonFable and AdventureQuest had a crossover mission.
  • Also, AdventureQuest and WarpForce are in the same period of time, but it began with a crossover from AdventureQuest.
• Alchemist Code has a lot of collaborations and crossovers with famous series such as Fate/stay night, Disgaea, Fullmetal Alchemist (2003) and so on. However, the most notable crossover is with the game Phantom of the Kill as not only they frequently collab with each other, but also they were published by the same company that published them, Fuji Games for Japanese version while Gumi Inc. is for the Global version.
• Aliens vs. Predator. The Atari Jaguar game and the two PC games are considered classics in the FPS genre.
• All Star Fighters is a crossover of the various games made by D3 Publisher from its Simple series of budget games, of which the most notable include the Onechanbara series and Earth Defense Force series.
• The Angry Birds series has a couple of these.
  • Angry Birds Rio is one with the film, as the poachers capture the birds, who escape and set out to rescue Blu and Jewel. Subsequent levels are set in the movie's Rio de Janiero and have the birds targeting the marmosets or bird cages instead of the usual pigs, and boss battles with Mauro and Nigel, the film’s villains. Blu and Jewel are also available as ammunition in some levels.
  • The "Red's Mighty Feathers" episode in the original game is one with Bad Piggies, as Red tries to bust the pigs' various contraptions to keep them from making off with an egg.
  • There's also Angry Birds Star Wars and Angry Birds Transformers.
• Taito combined two of its most famous series to create Arkanoid vs. Space Invaders.

  • Mighty Gunvolt (aka Gal*Gunvolt) is, as reflected in both titles, a crossover between Gunvolt, Gal*Gun, and Mighty No. 9. Hence, characters and bosses from all three series show up.
• In the Story Mode of Battle Princess Madelyn, Don Ramiro of fellow GnG-alike Maldita Castilla shows up to give Madelyn advice and aid when she travels to his native Spain.
• Battletoads and Double Dragon: The Ultimate Team was one of the earliest intercompany video game crossovers, which was made possible by the fact that both series were published in America and Europe by Tradewest. The game itself is really a Battletoads game with Double Dragon characters as guest stars (some of which were misnamed).
• BlazBlue: Cross Tag Battle is a Tag Team fighting game that initially featured characters from BlazBlue, Persona 4: Arena, Under Night In-Birth, and RWBY. Later updates added characters from Arcana Heart, Senran Kagura, and Akatsuki Blitzkampf.
• Blockland has a Robloxian add-on that can make it be this.
• Brave Frontier has recruitable characters from Chain Chronicle and vice versa. The characters may come from separate universes, but they are naturally under the same game ownership of Gumi.
• Capcom has something of a history with these, with Marvel vs. Capcom: Infinite being the latest installment.
• Capcom and Valve are coming together to have a crossover of sorts in each other's games. For Valve, they are bringing Rochelle, Coach, Ellis and Nick (the survivor characters) to Resident Evil 6 on the PC in Mercenaries mode. For Capcom, they are bringing the Lepotitsa, Napad and Ogroman as special infected counterparts to Valve's special infected for Left 4 Dead 2.
  • Way before that, thanks to players modding the game, you can have various characters from many other games be playable within Left 4 Dead and Left 4 Dead 2.
• Cartoon Network: Punch Time Explosion features characters from across Cartoon Network's wide selection of shows all duking it out, Super Smash Bros. style.
• Club Penguin has various parties focused around other Disney works, where rooms are decorated themed around the work, party-exclusive rooms based on the work, outfits from the work are made available, and the characters are meetable.

• Cross Edge is this in and out, with characters from the Disgaea, Darkstalkers and Atelier Series franchises making playable appearances (some, like Marie from Atelier Marie, being shown to international audiences for the very first time).
• DanMachi: Memoria Freese:
  • The Kino's Journey crossover, Travelers and the Labyrinth Country featured Kino herself(In both three and four-star, plus the schoolgirl version from Gakuen Kino when it was added during the rerun.), Shizu, and Photo, as well as Hermes(the god), dressed as Kino, as Adventurers, while Ti alongside Hestia, who was dressed as Photo, was an assist.

  • The Attack on Titan crossover, Attack on Orario, Featured Eren, Levi, and Mikasa, plus Bell and Ais, dressed in the attire of the former three, as Adventurers. It also had Armin and Titan!Eren as assists.
  • Ais Catastrophe crosses over with Date A Live, During the event in its first run, it had two sets of summon-able characters. The Date set features Tohka and a Ais(dressed as Tohka's inverse form) as Adventurers while also featuring Kotori as an assist. The Live set featured Kurumi and Origami as adventurers while Hestia, dressed as Kotori, can be summoned as an assist. Kaguya can also be earned as an assist by clearing the event story. The Fragment set issued during the rerun includes Shido and Kotori(In spirit form) as adventurers.
  • Dungeon and Goblins crosses over with Goblin Slayer. Appearing characters include Goblin Slayer himself, Priestess, Noble Fencer, High Elf Archer, Sword Maiden, and Cowgirl. Cowgirl and Heavy Warrior-dressed variants of Chigusa and Ouka respectively also appeared. Sword Maiden as well as forms of Amid and Ryu dressed as Sword Maiden and High Elf Archer respectively also appeared during part 2.
• Dariusburst: Chronicle Saviours features all the fighters from previous Darius games and also includes other characters from various Taito and Sega video games as DLC packs.
• Densetsu no Stafy 3 features a cameo by Wario in the eighth world. You have to activate some of his Wario Land 4 transformations in order to make your way through the stages. He ropes Starfy into helping him seek the ruins' treasure.
• Diddy Kong Racing for the Nintendo 64 is unusual in that it crossed Donkey Kong Country with two games still in development when it was released: Banjo-Kazooie and Conker's Twelve Tales (which later became Conker's Bad Fur Day). Banjo and Conker were removed from the Nintendo DS version, obviously due to Rare and Nintendo parting ways. They were replaced by Tiny Kong and Dixie Kong.
• Dissidia Final Fantasy. It's the main heroes and villains of Final Fantasies I-XII beating the ever-loving crap out of each other!
• The retail version of the DoDonPachi DaiFukkatsu Black Label 360 port features an Arrange Mode that crosses DoDonPachi over with Ketsui, with scoring elements, player ship, and True Final Boss taken right out of Ketsui.
• While we're at it, the first official mod for Skyrim, after the long-awaited HD Texture Pack... was a collaborative effort between Valve and Bethesda, showing just where that adorable little Space Core wound up.
  • And one of the fans wrote a mod that adds a crashed SSV Normandy from Mass Effect.
  • The Conan Hyborian Age mod basically uses the Conan the Barbarian setting as a distant past of the Tamriel setting, with a few alterations to the former in order to fit the Elder Scrolls lore (like Crom being renamed "Shor"). The dungeon serving as the mod's core, the Hyborian Mound, is itself a combination of the mound in which Conan finds his sword and Thulsa Doom's lair.
  • The Relics of Hyrule mod adds many different weapons, armor, enemies, lore and location inspired by the Legend of Zelda series, into the land of Skyrim and Solstheim. It's main premise is that Skyrim rose from the ashes of the once mythical kingdom after the Dark Army swept through, hence why its relics are scattered about for the player to find and use.
  • The Nintendo Switch release of Skyrim allows you to find items from The Legend of Zelda series, such as Link's Tunic from Breath of The Wild, the Master Sword, and the Hylian Shield.
• Final Fantasy XIV engages in Dualvertisement at times, with events featuring crossovers with other games such as Dragon Quest and other Final Fantasy games. The alliance raid questline from the Shadowbringers expansion, YoRHa: Dark Apocalypse, stands out in crossing over the world of FFXIV with NieR: Automata and, in the latter half of the questline, Drakengard.
• Fire Emblem has two.
  • Tokyo Mirage Sessions ♯FE is a crossover between the Fire Emblem and Shin Megami Tensei franchises, featuring an original story in Tokyo with Shin Megami Tensei's dungeon gameplay, featuring Fire Emblem characters as Mirages that work with the characters. The Fire Emblem characters included are mainly from Shadow Dragon and Awakening.
  • Fire Emblem Warriors is a crossover between the Fire Emblem and Dynasty Warriors franchises, featuring a more Fire Emblem-esque story even taking place in a medieval world, with Fire Emblem characters from the worlds of Shadow Dragon, Gaiden, The Blazing Blade, Awakening, and Fates showing up to help the protagonists.
  • Special mention goes to Code Name: S.T.E.A.M, which is a Steampunk game with historical characters and fables. AND Marth, Ike, Robin, and Lucina, if you have their amiibo.
• Forza Motorsport 4 features the Top Gear (UK) test track, and Jeremy Clarkson will provide commentary on dozens of cars in the Autovista mode. All the Reasonably Priced Cars from the UK and US Top Gear will show up as well.
  • On the subject of Top Gear, Forza Horizon 4 features The Top Gear Horizon Special, a storyline where the player takes control of the Stig and races through various challenges with narration from Chris Harris.
  • The Warthog from Halo will appear as an Easter Egg in the Autovista mode with Cortana (Jen Taylor) providing the commentary for it in the place of Clarkson. Unfortunately, it's not drivable.
  • The Warthog finally made a playable appearance in Forza Horizon 3, and better yet, in FH 4, a Showcase event has you assume the role of Master Chief in a race against a Pelican on a Halo ring.
  • Forza Motorsport 6 features the Chryslus Rocket 69 from Fallout 4 as DLC.
• The finale of Ghost Recon: Advanced Warfighter 2 has the Ghosts call in an air strike, and in H.A.W.X., you get to play the mission from the jet fighters' point of view. A similar crossover occurs between Ghost Recon: Future Soldier and HAWX 2.
• Granblue Fantasy is not only a Fantasy Kitchen Sink within its own universe, but it's also so in a meta sense, as it has been the host of several events meant to join the universes of different copyrights with itself. At the time of this writing it has crossed over with Street Fighter, THE iDOLM@STER: Cinderella Girls, Slayers, the Tales Series, Sakura Wars, Samurai Shodown, Katsugeki/Touken Ranbu, Cardcaptor Sakura, Attack on Titan, Love Live! and Persona 5.
  • Shadowverse from the same company has started to make crossovers with various franchises allowing you to play as characters from those. As of writing it's limited to Fate/stay night and Street Fighter, so it's very possible to have an epic battle where Ryu faces Saber ... using a children's card game.
• Half-Life and Portal were originally different universes altogether. (GLaDOS vaguely alludes to the events of Half-Life once in passing, but that was just an easter egg.) But then! In Portal 2 you can find the drydock for a ship called the Borealis, and Half-Life 2: Episode 2 ends with Gordon Freeman about to set off to find it.
  • The shared universe is not only an allusion in the first game - in several rooms the player can find projectors with slides explaining explicitly that Black Mesa is a (hated!) competitor of Aperture Science.
• Heroes of the Storm is a MOBA which crosses over Blizzard Entertainment's magnum opus games, the newest one, and some of their classics into one big fun brawl.
• Honkai Impact 3rd had two crossovers so far, as of making this entry. One with the anime Neon Genesis Evangelion and another with its sister game Genshin Impact. Both featured unique crossover event stories, outfits based on that series and a guest character (Asuka and Fischl respectively).
• Early editions of Sierra's Hoyle's Official Book of Games series featured characters from other Sierra games as playable opponents, allowing players to play a few hands of Crazy Eights with the likes of Dr. Brain, King Graham, and Laura Bow, or challenge Roger Wilco to a game of checkers.
• Jewelry Master Twinkle, an already-obscure Puzzle Game, is actually a crossover between the Tetris TGM-like game Jewelry Master and the even-more-obscure mahjong game Taikyoku Mahjong Net-De-Ron.
• Jump Super Stars: A Mascot Fighter featuring several characters from Shonen Jump.
  • And prior to that, there were Famicom Jump: Hero Retsuden and Famicom Jump II: Saikyō no Shichinin.
• Kingdom Hearts — Where Disney and Final Fantasy meet.
• The King of Fighters — Featuring characters from Fatal Fury, Art of Fighting, Psycho Soldier, Ikari Warriors, and one or few from other SNK titles, as well as some exclusives like Kyo Kusanagi and his partners and rivals.
  • One game in its 3D spinoff Maximum Impact (Mainly MI:2) had Hanzo Hattori from Samurai Shodown and Fio Germi from Metal Slug as unlockable characters.
  • Metal Slug 6 and 7 featured Ralf Jones and Clark Still (originally from Ikari Warriors, but using their appearances from the KOF franchise) as playable characters, with fellow Team Ikari member Leona appearing as a DLC character in Metal Slug XX, a PSP re-release of Metal Slug 7.
• Konami has a great story with this.
  • Wai Wai World was the first cross-over in console video game history.
  • Konami's Parodius series.
  • Konami Krazy Racers.
  • DreamMix TV World Fighters, is a crossover between Konami, Hudson and Takara.
  • Sunday VS Magazine: Shuuketsu! Choujou Daikessen, is crossover between two manga mazine giants, Weekly Shonen Sunday and Weekly Shonen Magazine.
  • The Vic Viper appears as a Transforming Mecha in Zone of the Enders 2.
  • Some characters in pop'n music come from other Konami franchises, as a result of having songs or remixes of songs from games they appeared in being put in the game:
    • Vic Viper, in his NES Gradius form ("Gradius -Full Speed-", "A Shooting Star")
    • Simon Belmont ("Akumajo Dracula^note the Japanese name for the Castlevania series Medley Hybrid".)
    • Goemon ("Ganbare Goemon Medley")
    • Emi and Afro, exactly as they appeared in DDR ("Flowers" and "Afronova Primeval," respectively, as well as "DDR Megamix" for Afro)
    • Tran (various IIDX songs)
    • SigSig, exactly as she appeared in IIDX ("SigSig")
    • Dingo and Ken ("Beyond the Bounds")
• Koumajou Densetsu, Touhou Project meets Castlevania.
• Last Cloudia:
  • The Collection of Mana Event featured Randi, Primm, and Popoi as potential warriors to summon, had an event that was set in the Mana Fortress, and had Arks based on the first three games.
  • There was also a crossover with Dr. STONE as well, The Science-user from Another World. Senku and Kohaku are summon-able during this. It was followed up with Tsukasa Shishio's Challenge which adds Tsukasa himself to the roster.
• Sega's maimai arcade game enjoys doing this every now and then.
  • The Sega section is Exactly What It Says on the Tin. The songs are from Sega games, like "Live and Learn", "Angels With Burning Hearts", and "Save This World".
  • An update to maimai ORANGE PLUS added tracks from Persona 4: Dancing All Night, such as Pursuing My True Self and Time to Make History.
  • The TOUHOU PROJECT section consists entirely of rearrangements of Touhou Project tunes. The niconico section consists almost entirely of Vocaloid tracks.
  • The GAME & VARIETY section borrows songs from other games or companies, such as Got more raves?, Kitasaitama2000, and FLOWER.
  • The reverse also happened with Groove Coaster, Taiko, and jubeat, which received the maimai original song Garakuta Doll Play in a similar event to the above three songs.
  • And then there's Karma by Bump of Chicken, from Namco's Tales of the Abyss. Although strangely, it was listed under Anime and used a custom-made PV instead of the game's opening cinematic.
  • maimai PiNK added Gera Gera Po no Uta, the theme song from the anime and game of Yo-kai Watch.
  • On the other end of the scale, maimai likes to appear in Phantasy Star Online 2 on occasions, allowing players to purchase replicas of the machine that also function as a Jukebox, as well as Music Discs for some of the game's original tracks. Appropriately, Quna's Our Fighting was added to maimai ORANGE in an update.
• Mario and Sonic at the Olympic Games, a Massive Multiplayer Crossover of the two biggest mascots in video games and their ensemble competing in the Olympic Games.
• Even the venerable Mario Kart series does this... although most of the characters are Marioverse stalwarts, Donkey Kong and Diddy Kong are their Donkey Kong Country incarnations. Being co-developed by Namco, the arcade games go further than the home console versions and include characters from Pac-Man, Taiko no Tatsujin and, oddly enough, Tamagotchi.
  • GP and GP 2 feature Diamond City from WarioWare as the location of a few playable tracks. While Wario himself does have ties to Marioverse, this is one of the few times something from the WarioWare series made an appearance in a Mario game.
  • Mario Kart 8 includes characters, karts, and stages from The Legend of Zelda, Excitebike, F-Zero, and Animal Crossing in its DLC. The Updated Re-release Mario Kart 8 Deluxe adds the Inklings from Splatoon and a battle stage based on the first game's Urchin Underpass stage as well.
• Mari0 is a fan-made freeware crossover between Super Mario Bros. and Portal. You play as Mario... except you have a portal gun.
• There are also two Mario RPG series, Mario & Luigi and Paper Mario, crossing over in Mario & Luigi: Paper Jam, making it a rare example of a crossover between two works in the same franchise.
• Mario + Rabbids Kingdom Battle; as its name suggests, crosses the Mario franchise with the Raving Rabbids franchise. The same goes for its sequel.
• Owen and Kate from Master of the Monster Lair also appear in My World, My Way.
• Mighty No. 9, Azure Striker Gunvolt, and Gal*Gun: Double Peace's respective protagonists were brought together in Inti Create's crossover game, Mighty Gunvolt (or Gal*Gunvolt if you live in Japan and have a PlayStation system), which was a simple Mega Man-styled action platformer. A later sequel, Mighty Gunvolt Burst also brought these characters together again while featuring a Burst combo system and the ability to customize each heroes' abilities and weapons.
• Mortal Kombat vs. DC Universe
• Mortal Kombat 9 features Freddy Krueger, as well as Kratos in the PlayStation 3 version. Mortal Kombat X lacks Freddy, but ups the ante by including Jason Voorhees, a Predator, Leatherface, and a Xenomorph.
• M.U.G.E.N is technically the ultimate crossover game, as, for example, you can fight a Touhou character with a Mortal Kombat character. That's just a basic example, as well!
• Namco High is a Dating Sim that stars characters from Galaga, Klonoa, Rolling Thunder, Homestuck and more. In a high school setting...
• In addition to some already present in the KOF series, NeoGeo Battle Coliseum also added characters from other SNK titles that the KOF series didn't add, as well as some ADK titles (due to SNK Playmore's purchase of ADK after it filed for bankruptcy).
• Nexus Clash isn't this trope per se, but the cyclical nature of its universe and the willingness of Nexal souls to adopt new identities that suit them mean that it's cluttered with people who identify as all sorts of fictional and mythical figures. The magic of the Nexus works as a Literal Metaphor to make these people as much like what they identify with as possible.
• NiGHTS is featured in both of the Sonic Adventure games, and while he bears no real significance to the plot, he is a part of a level in each, moreso in Sonic Adventure.
• NiGHTS and other NiGHTS into Dreams… characters also make an appearance in the the Deadly Six edition of Sonic Lost World. DLC for the game also includes both a Yoshi's Island and Zelda Zone.
• Ryu Hayabusa in Dead or Alive. Also done in reverse, with Ayane appearing as a supporting character in the new Ninja Gaiden games.
  • Dead or Alive 4 has Nicole-458, a Spartan from the Halo verse.
  • Dead or Alive 5 has Guest Fighters from Virtua Fighter and SNK appear, as well as Naotora Ii from Samurai Warriors
• PAYDAY: The Heist, with its gameplay so inspired by Left 4 Dead, went the full mile and released a heist based on Mercy Hospital from L4D's "No Mercy" campaign.
• PAYDAY 2 takes it even further and has (at last count) had a crossover with Hotline Miami and its sequel, John Wick, Counter Strike: Global Offensive, Swedish DJ Alesso, Point Break (2015), Hardcore Henry, Goat Simulator, Scarface, Reservoir Dogs, SpeedRunners, and Enter the Gungeon. Yes, really.
• In Persona Q: Shadow of the Labyrinth, the full casts of Persona 3 and Persona 4 end up becoming involved in the mystery of the Labyrinth.
  • The sequel Persona Q2: New Cinema Labyrinth also adds the cast of Persona 5.
• PlayStation Move Heroes is a three-way crossover with Jak and Daxter, Ratchet & Clank, and Sly Cooper.
• Pokémon Conquest: Pokémon meets Nobunaga's Ambition.
• Poker Night at the Inventory has the RED Heavy, Strong Bad, Tycho, and Max get together for a game of poker. The sequel adds Sam, Claptrap, Brock Samson, and Ash Williams, with GLaDOS as the dealer.
• Pop 'n Pop, an obscure puzzle game does this with both the gameplay and the characters. The gameplay is essentially Puzzle Bobble with a few elements from Space Invaders thrown in while the roster is made up of characters from various Taito arcade games.
  • Averted in North America, where it was rebranded as a Yogi Bear game.
• Project × Zone was a massive crossover between Bandai Namco Entertainment, Capcom, and Sega. In its sequel, Nintendo also got in the mix.
• Power Rangers: Legacy Wars, in addition to being a Massive Multiplayer Crossover of numerous Power Rangers series, has a handful of characters from Street Fighter (Ryu, Chun-Li, Cammy, Guile, Akuma, and M. Bison) throwing down.
• Professor Layton vs. Ace Attorney, obviously combining Professor Layton and Ace Attorney.
• Putt-Putt and Fatty Bear's Activity Pack.
• Puyo Puyo and Tetris, two popular Falling Blocks games come together for Puyo Puyo Tetris.
• This is the whole premise of Rakenzarn Tales. The world of Rakenzarn is home to every fictional character. We probably won't see them all.
  • Its sister series, Rakenzarn Frontier Story, is this as well with the added premise of Alternate Universe. It's possible this is an even BIGGER crossover than Rakenzarn Tales since we'll be seeing different versions of characters. This includes two versions of Mario: the Mario we all know and love... and the Mario from The Super Mario Bros. Super Show!.
• The Rival Schools games have had a few crossovers with Capcom's more popular fighting game series Street Fighter; the most obvious was Sakura Kasugano, Ryu's Hero-Worshipper, being a playable character in the console versions of the game. There is also a character known as Ran Hibiki, whose name is almost exactly the same as that of Dan Hibiki. Just what her relationship to him is undetermined, assuming there is a relationship at all and it is not simply an homage.
  • Ran's classmate, the unnamed Chairperson, also happens to study Dan's self-invented martial art, Saikyo-ryu, with predictable results.
  • Hinata also claims to be a student of "Masters-ryu Karate" in Nekketsu Seishun Nikki 2, which explains why some of her special moves have the same flame effect as Ken's Dragon Punch in Super Street Fighter II.
  • Also in Street Fighter, Cody, Guy, Rolento, and Sodom from Final Fight appear as playable characters in the Alpha series. The crossover between the two also carried over into the cartoon, which featured a retelling of Final Fight's storyline while adding Ryu and Ken.
• The Sega Superstars series subverts this at first, as it is essentially a collection of games based on Sega properties, but the second game, Superstars Tennis has Sega characters all play tennis together, playing the trope straight. Then there was a third racing game, which was a lot better than expected.
  • Before that we had, Fighters Megamix, which included most of Sega's 3D characters in a fighting game.
• The adventure game Sherlock Holmes: Nemesis features Holmes matching wits with Gentleman Thief Arsene Lupin.
  • There are stories and videogames which also cross him over with the Cthulhu Mythos.
• The Shin Megami Tensei spinoff Shin Megami Tensei Liberation: Dx2 has occasional crossovers featuring different franchises, allowing some characters to be summoned as limited demons. So far, the list includes Bayonetta, Devil May Cry, Berserk, Ghost in the Shell: SAC_2045, Sonic the Hedgehog, and The Seven Deadly Sins.
• The Sims 4 has characters based on Liberty, Travis, Summer, Candy, and Yuki from MySims, and Kaori from SSX was added in the Japan-themed "Snowy Escape" expansion pack.
• SINoALICE:
  • The game has a collaboration event with another Yoko Taro work, NieR: Automata, focusing on the amusement park boss Simone. 2B, 9S, A2, Emil in his No. 7 form, and several weapons from the game also make an appearance in this crossover.
  • Another crossover event with Drakengard 3 featured Zero, One, Accord and Mikhail in human and dragon form, as well as some weapons (including weapons from the first 2 Drakengard games) and enemies from that franchise like the Intoners turned into Nightmares. The event's revival in June 2019 later added Two, Three, Four and Five.
  • The third Yoko Taro work to get a crossover event is the original NieR (specifically the Replicant version), with both versions of Brother Nier, Kaine, a human Emil and Devola and Popola as a single character being playable. The June 2020 revival run adds Yonah as well as the King of Facade as a double unit with Fyra.
  • Non-Yoko Taro works included for crossover events are Tsuri Star, Space Invaders, Final Fantasy Brave Exvius, Code Geass, Re:Zero, Higurashi: When They Cry, Rozen Maiden and virtual idol group Gems Company^noteThe group's music is composed by the same group who did the music for SINoALICE. From the That Time I Got Reincarnated as a Slime event onwards, crossover events will be held simultaneously between the JP and Global servers.
• Soul Sacrifice Delta has crossovers from other Play Station Vita games, such as Freedom Wars, God Eater 2, Toukiden, Gravity Rush, Wild ARMs, Ragnarok Odyssey Ace, and Phantasy Star Online 2. ^note The last two are exclusive to the original Vanilla Edition, and the last one is exclusive to Japan. Players can battle bosses like Dionaea (Freedom Wars), Marduk (God Eater 2), and the Chthonian and Abyssal Fiends (Toukiden), and unlock weapons and costumes from their respective universes, like the Sinner's costume and Thorn, the God Eater's costume and God Arc, and the Mononofu armor.
• The Soul Series is famous for this. Guest characters have included Link, Spawn, Heihachi, Lloyd Irving, Kratos, Yoda and Darth Vader, and Ezio Auditore da Firenze.
• StarCraft had an unofficial crossover with Ranma ½ in a campaign called Vision of the Future. Unfortunately, the file is currently unavailable as the site that had it expired.
• Every Mario game that Square Enix has worked on (Super Mario RPG, Fortune Street, and Mario Hoops 3-on-3) has included characters from their own series in some form. SMRPG features a Superboss utilizing the boss, victory, and Prelude themes from Final Fantasy IV, Hoops features a Ninja, a White Mage, a Black Mage, a Moogle, and a Cactuar as unlockable characters, and roughly half the roster of FS is made up of Dragon Quest characters (with some Final Fantasy characters appearing in previous Japan-only installments).
• Super Robot Wars is a Massive Multiplayer Crossover of various mecha shows, games, and other media by Banpresto (later a subsidiary of Bandai Namco Entertainment) until the same company also gave us Another Century's Episode. Said developers also made Namco × Capcom and Project × Zone.
• Super Smash Bros. is a Mascot Fighter with Nintendo's flagship franchises duking it out.
  • While the roster of Nintendo characters was small in the original game, it increased considerably in Super Smash Bros. Melee, which not only added more characters to the existing universes but also went as far as introducing characters from franchises that were relatively obscure back then, such as the Ice Climbers, Marth and Roy, and Mr. Game & Watch.
  • Starting with Super Smash Bros. Brawl, it's also crossed-over with third-party characters Solid Snake and Sonic the Hedgehog. Super Smash Bros. for Nintendo 3DS and Wii U extends it with Pac-Man, Mega Man, Ryu (and later, Ken), Cloud Strife (and later, Sephiroth), and Bayonetta. As of Super Smash Bros. Ultimate, Simon and Richter Belmont, Joker, the Heroes of Dragon Quest ^* specifically, those of XI, III, IV and VIII, Banjo & Kazooie, Terry Bogard, Steve, Kazuya Mishima, and Sora have all joined as well.
  • Characters from other series are also represented in the later games through Mii Fighter costume DLC, including Virtua Fighter and Undertale. Ultimate also features third party Assist Trophy characters who come from series not represented by playable characters like Bomberman, Shovel Knight, and Rathalos (this one also being one of the bosses in the Classic and Adventure modes), as well as characters like Shantae and Rayman making cameos in Spirits mode.
  • Thanks to the first line of amiibo being made for Smash Bros., games compatible with amiibo have crossover content ranging from costumes in a One Piece game to the Fire Emblem characters being playable in Code Name: S.T.E.A.M.
• Starlink: Battle for Atlas features Star Fox characters in a original storyline in the Switch version.
• Namco's Tales of the World, starting with Nakiri Dungeon 3, and including the Radiant Mythology spin-offs, take characters from all the Tales of... titles, which otherwise only exist as spiritual sequels.
• Terraria:
  • The 1.2.4 update had a crossover with Pixel Piracy, introducing several pirate-themed items.
  • The 1.3.4 update was one big crossover with Dungeon Defenders 2, complete with a tower-defense-style invasion event featuring Etherian enemies and bosses, and piles of weapons and armor as rewards. Dungeon Defenders 2, in turn, received its own Terraria-themed crossover update.
  • And there's another for the 1.4.3, this time it was a massive crossover update with Don't Starve Together. On Terraria's end, it received the Deerclops, as well as Chester and a whole lot of new items. There was even a secret seed that allows the world made with it to mimic Don't Starve Together's darkness and hunger mechanics. And for Don't Starve, it received the Eye of Cthulhu (which is known as the Eye of Terror), an eyeball pet, and some additional items. Fittingly, due to the selling points of these updates- it was known as the Eye for an Eye update.
• Under Night In-Birth featured two Guest Fighters in the game's "Ex: Late" update: Eltnum, implied to be Sion Eltnum Altasia from Melty Blood; and Akatsuki, the protagonist of Akatsuki Blitzkampf.
• Universal Studios Theme Park Adventure is based on the real-life Universal Studios theme parks, and just like them, features attractions based on a variety of famous movies, including Back to the Future, Jaws, Jurassic Park, and a couple others. Woody Woodpecker acts as the game's guide and makes recurring appearances throughout the game to explain each ride.
• Unreal Championship 2: The Liandri Conflict featured Raiden from Mortal Kombat and Shao Kahn as an optional announcer. It helps that it was the first Unreal game being published by Midway Games.
• Wario Land: Legends of 6 Crystals is a fan-made Wario Land game that crosses over with My Little Pony: Friendship Is Magic. It also includes other characters and elements from Mortal Kombat, the main Super Mario Bros. games, and even Happy Tree Friends.
• A small one in the With Friends line between Stampede Run and Words With Friends; you can pick up letter tiles from Words as bonuses in Stampede Run. Get enough to spell out a word and you earn extra gems and XP.
• While it makes sense since they are a part of the same cosmology, most of Bioware and Obsidian's D&D-based games have subtle crossovers. Most notably, Baldur's Gate II features artifacts from some of the characters of Planescape: Torment, and one of said characters is also mentioned by an NPC in Neverwinter Nights 2.
  • Not surprising. The collusion started with Neverwinter Nights, but reached its height with Knights of the Old Republic. The first game is "Baldur's Gate with lightsabers." The second is "Planescape: Torment with lightsabers"
  • Perhaps less crossover than Continuity Cameo, but the fates of the characters from the TV show of Dungeons & Dragons is on a wall in Baldur's Gate II.
• Rage (2011) has Space Marine and Vault Boy bobbleheads.
• RoboCop Versus The Terminator is about RoboCop fighting against Skynet. There was also a comic.
• Iron Man and X-O Manowar in Heavy Metal is a crossover between Iron Man and X-O Manowar. There was also a comic.
• Senran NinNinNinja Taisen Neptune: Shojo-Tachi no Kyoen is a crossover between Senran Kagura, Neptunia, and it even features a gender-swapped version of Goh from Shinobido as a special guest.
