Indie Battle Colosseum (インディーバトルコロシアム Indī Batoru Koroshiamu) is a tag-team fighting game starring characters from various indie and doujin games. It was released for Nintendo Switch, PlayStation 4, PlayStation 5, Xbox One, Xbox Series X/S, and PC. An arcade version, running on the Taito Type X3 system, was also released.
The gamplay is similar to the Marvel vs. Capcom series, where the player can form up a team of four characters of their choosing (three playable, plus one Assist/Striker).
There are two different playstyles, the X-Gear and Y-Gear. The X-Gear lets the player have a five-level super meter. The Y-Gear allows all normal and special moves to cancel each other, ending the combo with the character's Level 1 super.
