Having established both the Street Fighter series and two Marvel-based fighting games, Capcom made the popular decision to cross over the two universes, creating what would become the long-running Marvel vs. Capcom franchise. X-Men vs. Street Fighter allows each player to choose two fighters, who can trade off during combat and join forces for special attacks, and includes features from Capcom's other Marvel games such as super jumps, in-air combos and the Hyper Combo Gauge for supercharged attacks.
