is a crossover fighting video game developed and published by Capcom. It is the sequel to X-Men vs. Street Fighter and the second installment in the Marvel vs. Capcom series. The game was first released as an arcade game in 1997. It then received ports to the Sega Saturn in 1998 and the PlayStation in 1999. The gameplay and aesthetics of Marvel Super Heroes vs. Street Fighter remain similar to X-Men vs. Street Fighter. Each player selects two characters to compete in a one-on-one tag team fight, attempting to defeat the opposing team. The game replaces most of the X-Men cast from the previous installment with characters from other Marvel properties. In addition, it introduces a new gameplay mechanic known as the "Variable Assist", which would be used in future Marvel vs. Capcom titles. Much like its predecessor, the game received generally positive reviews for its gameplay, sprite animations, and character roster. The Sega Saturn version, utilizing the 4 MB RAM expansion cartridge, was praised for being an arcade-perfect conversion. Due to the memory limitations of the PlayStation, tag team battles were, once again, removed from its port, resulting in more mixed critical reception. A sequel, Marvel vs. Capcom: Clash of Super Heroes, was released in 1998. Gameplay Marvel Super Heroes vs. Street Fighter is the second installment in the Marvel vs. Capcom series of 2D fighting games. It utilizes the same one-on-one tag team format previously employed in X-Men vs. Street Fighter. The player chooses a team of two fighters, each sporting their own life gauge; at the start of the match, the first selected character is controlled by the player, while the second character remains off-screen and acts as support. Using a combination of joystick movements and button presses, the player must execute various moves to deplete the opposing team's life gauges. The first player to completely drain the opponent's health is declared the winner. If the timer reaches zero, the player that possesses the most health wins. The most notable gameplay change in Marvel Super Heroes vs. Street Fighter is the addition of the "Variable Assist". With the Variable Assist, the player can summon their off-screen character to perform a special move without changing their currently-controlled character, opening new possibilities for combos during battle and greatly expanding the role of the secondary character. The ability to use assists would later become a signature gameplay element used in
