Marvel vs. Capcom: Infinite[a] is a fighting video game developed and published by Capcom. It is the sixth main entry in the Marvel vs. Capcom series of crossover games. Like previous installments, players control characters from both the Marvel Comics and Capcom universes to compete in tag team battles. Infinite features two-on-two fights, as opposed to the three-on-three format used in its preceding titles. The series' character assist moves have been removed; instead, the game incorporates a tag-based combo system, which allows players to instantly switch between their two characters to form continuous combos. It also introduces a new gameplay mechanic in the form of the Infinity Stones, which temporarily bestow players with unique abilities and stat boosts depending on the type of stone selected.
Infinite was released in September 2017 for PlayStation 4, Xbox One, and Microsoft Windows. The game received mixed reviews; critics praised its new gameplay elements, but criticized its presentation, particularly its art direction, and character roster. The game also underperformed commercially. Capcom originally expected the game to sell two million units; however, it missed its sales target, selling approximately one million copies by the end of December 2017.
