Kakuto Chojin is a fighting game generally set in a three-dimensional arena. There are thirteen fighters, each with their own arena. Each character has two styles of fighting; the "Kakuto" style is the only one available at first, with the "Chojin" style acquired after beating Story mode with a character. Kakuto Chojin attempts a different fighting system in that it lacks buttons meant specifically to punch and kick, instead assigning controls to high, middle and low attacks, along with the ability to unleash a special attack. The left trigger allows for free movement around an arena, while the right trigger is used for blocking and an attack modifier. Besides the Story mode, there are the standard Practice and Vs. modes. Kakuto Chojin allows for a Battle Royale with four players at once.
