As opposed to the other crossover fighting games released by Capcom, in which the player must eliminate all the opponent's fighters to win, victory conditions are more similar to Tekken Tag Tournament, in which the first player to have one of their fighters' health bars reduced to zero loses the round, thereby the player who wins the most rounds wins the match.

Additionally, each fighter possesses one special attack that can be charged into an EX Attack or Super Art without any cost to the Cross Gauge. As fights go on, players build up power in a three-sectioned meter at the bottom of the screen referred to as the Cross Gauge, which allow the player to perform various techniques depending on how much of the gauge is filled, such as EX Attacks, Cancels, Super Arts and various Cross techniques detailed below. These fighters can be switched out normally, or during certain combos.

Both sets of characters are controlled using the Street Fighter six-button system, but the Tekken characters are able to perform Tekken style combos using the primary four buttons in a similar fashion to the Tekken four-button system. Players each choose two fighters from the Street Fighter and Tekken series. Developed by Capcom, the core gameplay is similar to that of the Street Fighter series, incorporating elements such as Super Combos and EX Attacks.
