Marvel Super Heroes vs. Street Fighter(マーヴルスーパーヒーローズVS。ストリートファイター) is the fourth Marvel Comics-licensed fighting game produced by Capcom (see Marvel vs. Capcom series). It is a sequel to X-Men vs. Street Fighter which replaces most of the X-Men characters with characters from Marvel Super Heroes. In an attempt to balance the previous games' problems, the game engine was altered, although it remained aesthetically the same. The game was released for the arcade in 1997, Sega Saturn in 1998 and Sony PlayStation in 1999.
The game uses the same tag-team format previously employed in X-Men vs. Street Fighter. In addition to all the features introduced, the player can now summon their partner to perform one of their special moves without changing their currently-controlled character.
Most of the Street Fighter characters from the previous game returned, with the exception of Cammy and Charlie, who are replaced by Dan and Sakura. However, all of the X-Men characters from the previous game, with the exception of Cyclops and Wolverine, are replaced with characters from Marvel Super Heroes.
Like in X-Men vs. Street Fighter, the single-player mode consists of matches against other tag-teams and a two-on-one fight against Apocalypse. However, the match against the player's default character and his partner is replaced with another two-on-one match, this time against a cyborg version of Akuma. The character who deals the finishing blow to Cyber-Akuma will have their ending played.
All of the backgrounds from X-Men vs. Street Fighter returned for this game are redone in palette swap fashion.
