X-Men vs. Street Fighter

The gameplay system is similar to previous games, adding a tag-team feature. The player controls one character at a time, while the other awaits off-screen. The starting character can tag in their partner by hitting specific buttons; the tag partner will jump in with an attack and taunt the enemy. Resting characters gradually recover health. Players can execute variable attacks, which depend on button combinations.

The tag team feature has been omitted from the PlayStation version due to memory limitations, making it impossible for fighters to heal during a fight since switching out isn't possible.

There are differences between the Saturn and PlayStation versions of the game. The Saturn version can reach turbo speed up to 8, while the PlayStation version is limited to 4, even on the same speed setting. The PlayStation version's combo meter fills twice as fast as the Saturn version's.

The PlayStation version has exclusive Training and Survival modes, allowing supers to be canceled early with new ones linked in. It also displays icons indicating how a round of fighting was won, and removes frames from animations.
