Unlike the previous game in the series, the point character of a Marvel vs. Capcom team cannot summon the offscreen partner for an assist attack; instead, an assist character is randomly selected before the match begins. This character can be summoned a limited number of times in battle to attack the opponent in parallel. Codes can be used to force the system to select a certain assist character. The Duo Team Attack allows a player to control both characters on his or her team simultaneously for a brief period of time; the characters have unlimited use of their super moves during this time. Since some characters have hard-to-avoid super moves that do substantial damage if blocked, the Duo Team Attack can lead to tactics that are oriented around activating it before an opponent could. Since the PlayStation version only allows one character to play a point, a Duo Team Attack will call the assist character repeatedly without cost during its duration.
