Descpription:
X-Men vs. Street Fighter uses a system similar to the
style developed in Marvel Super Heroes, and adds the tag team
gameplay feature. Instead of the usual best-two-out-of-three round
format, the game's matches consist of two-on-two battles between tag teams.
The player controls one character at a time, while the other awaits off-screen.
The starting character can tag the waiting one in at any time by hitting
the Hard Punch and Hard Kick buttons, which activates the "Variable Attack";
the tag partner will jump in with an attack and taunt briefly.
During their taunt, they are vulnerable to counter attack. The
dormant character will able to recover a portion of their vitality,
while the current character is fighting. If one character loses all
of their vitality, then the tag partner will automatically come to play.
A match is over when both members of a team are defeated.
