Battle Raper

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 artwork and animations, as well as featuring an option to allow to freely molest any of the four female fighters (Mai Kisaragi, Suzume Hachisuka, Fa Taolee, Chihaya Kagami: the only male fighter is Zenon).

The game has gained notoriety because of its forced sex elements and was credited to be one of the Japanese adult games that not only resulted in "a widely publicised outcry in the West which only started years after the fact" but also led to the establishment of the Ethics Organization of Computer Software in 2009. Battle Raper was included on the GamesRadar's lists of the seven "most evil" video games in 2007: "At first, seeing female brawlers beat each other's clothes off is pretty amusing in a twisted way, but the streaming tears that come when the raping begins quickly kills any quirky humor or titillation to be had with this sick hentai title." and the 12 weirdest fighting games in 2008 ("Humiliation, rape and degradation are wrapped up in one package of shame, that's not only a shitty fighting game, but a sick idea as well"). The Washington Post included it among the 15 most morally controversial video games. The game was banned on the streaming video service Twitch.
