Like its predecessors, Marvel vs. Capcom: Infinite is a 2D fighting game in which players compete against each other in tag team combat using characters from both the Marvel Comics and Capcom universes.[1] Players must knock out the opposing team by repeatedly attacking the opponent and draining their health bar.[2] Infinite features two-on-two partner battles, similar to Marvel vs. Capcom: Clash of Super Heroes and earlier installments in the franchise.[3][4] Unlike past entries, the game does not allow players to use traditional call-in assist attacks from off-screen characters; instead, Infinite utilizes a "free-form" tag system, known as "Active Switch", which shares similarities with Marvel vs. Capcom 3's "Team Aerial Combo" system and Street Fighter X Tekken's "Switch Cancel" system.[4][5][6] Players can immediately switch between their team members at any point, even while mid-air or during attack animations.[4][5][7] This provides players with the abilities to create their own offensive or defensive assists through the tag system and form continuous combos between their two characters
