several future installments of the Marvel vs. Capcom series. Modes The arcade, Sega Saturn, and PlayStation versions of Marvel Super Heroes vs. Street Fighter share Arcade Mode and Versus Mode. In Arcade Mode, the player fights waves of artificial intelligence-controlled teams, culminating in a penultimate battle against the boss character, Apocalypse, who previously appeared in X-Men vs. Street Fighter. Upon defeating Apocalypse, the player must win against the final boss character, Cyber-Akuma. The PlayStation version includes three exclusive game modes: Training, Hero Battle, and Cross Over. Hero Battle is an endurance mode which pits the player against the characters that they did not select. In Cross Over, the player and the computer opponent fight with the same team of characters; if the player is victorious, then the computer swaps one character from both teams. The PlayStation port also features a Gallery Mode containing promotional and character artwork, which are unlocked by completing various goals. Playable characters Marvel Super Heroes vs. Street Fighter features a roster of 17 playable fighters, with nine characters from the Street Fighter universe and eight heroes from the Marvel Universe. All of the X-Men characters featured in X-Men vs. Street Fighter, with the exception of Cyclops and Wolverine, are replaced with characters from other Marvel Comics properties, such as Captain America, Spider-Man, and the Hulk. Most of the Street Fighter characters from the previous game return, with the exception of Cammy and Charlie (although Charlie is actually still in the game as a palette swapped secret character named "Shadow"), who are replaced by Dan and Sakura. The Japanese arcade and console versions of Marvel Super Heroes vs. Street Fighter include an exclusive character named Norimaro (). Norimaro is an original character created and owned by Japanese comedian Noritake Kinashi, who represents neither Marvel nor Capcom. Due to licensing issues involving the character, Norimaro is not available in international releases of the game. In addition to the 17 immediately playable characters, the roster also contains six secret characters. The secret characters are palette swaps of existing fighters with different moveset properties, such as "Dark Sakura" and "Mecha Zangief"; Captain America's and Blackheart's palette swaps are renamed "U.S. Agent" and "Mephisto", respectively. Development and release As with X-Men vs. Street Fighter, Marvel Super Heroes vs. Street Fighter was initially developed for the CP System II arcade system board. The game debuted in Japanese and North American arcades in
