Marvel vs. Capcom: Infinite 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 announced during Sony's PlayStation Experience event in December 2016. Capcom initially lost the use of the Marvel license in 2012, after The Walt Disney Company decided to focus on self-publishing its own gaming titles; however, Capcom was able to reacquire the license after Disney dissolved its console publishing division. Infinite was designed to be more accessible than previous Marvel vs. Capcom games, resulting in several changes to the series' traditional mechanics. The game also features a larger emphasis on storytelling, with the series' first cinematic story mode. The plot follows the heroes of the Marvel and Capcom universes, who must work together to save their merged worlds against a new threat, Ultron Sigma.
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.
