Battle Raper has gained notoriety for its simulation of rape. This aspect was removed from the follow-up game Battle Raper II: The Game in 2005.

Battle Raper is a hand-to-hand combat 3D fighting game. The gameplay system features power-ups that can be picked up in the arena. The female characters can lose their clothes as they take damage and special moves include sexually explicit grapple attacks. Besides the single- and multiplayer modes, including Story mode, Battle Raper features the Extra mode for the additional unlockable content. It allows the player to see unlockable artworks and animations, as well as features an option to allow to freely molest any of the four female characters (Mai Kisaragi, Suzume Hachisuka, Fa Taolee, Chihaya Kagami: the only male character is Zenon).
