Marvel Infinity War is a fan-made game using the OpenBor engine. This beat 'em up hearkens back to the arcades of old, with 85 playable good guys and bad guys from the Marvel universe. Using a six-button control scheme, each character has a special move and an ultra move, along with special assist characters to summon during the heat of battle.
There are five different overarching teams of characters available, including the Avengers, X-Men, Cosmic, Street Level, and Villains. They each visit their own stages and battle different bosses.
