 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 final battle against the boss character , Apocalypse , who previously appeared in X @-@ Men vs. Street Fighter . Upon defeating Apocalypse in the console versions , the player must win against a second 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 .
