Marvel vs. Capcom is a series of crossover fighting games developed and published by Capcom, featuring characters from their own video game franchises and comic book series published by Marvel Comics. The basic gameplay of the Marvel vs. Capcom series was originally derived from X-Men: Children of the Atom and Marvel Super Heroes. Players compete in battle using characters with unique moves and special attacks. Using a combination of joystick movements and button presses, players must execute various moves to damage their opponent and deplete their life gauge, or alternatively, have the most cumulative health when the timer runs out. However, unlike the two aforementioned games, which focus on single combat, the Marvel vs. Capcom series revolve around tag team-based combat. Instead of choosing a single character, players select multiple characters to form teams of two or three. Each character on the team is given their own life gauge. Players control one character at a time, while the others await off-screen. Players are also free to swap between their characters at any point during the match.
