Marvel vs. Capcom is a hand-to-hand combat game featuring fighters from video games developed by Capcom and super-heroes from Marvel Comic Books. Capcom characters include Mega Man, along with various characters from Capcom's Street Fighter II series. Marvel heroes include Spider-Man and the Hulk, among others.

Marvel vs. Capcom allows players to choose two characters who fight as a tag team against two other computer-driven or human opponents. A third character is chosen by the computer for each team and comes into the match to assist when a character's energy meter is low. This third character cannot be controlled by the player. It will move to attack an opponent and then leave the screen. Marvel vs. Capcom features two styles of play which really only affect combo moves. Players choose between "EASY" and "MANUAL" combos at the start of the game. Easy combos only require button manipulations, while manual combos require button and joystick manipulation in tandem. There are 15 selectable fighters and dozens of hidden characters which serve as "third partners." ~ Anthony Baize, All Game Guide
