Batman: Arkham Asylum

Batman: Arkham Asylum is a video game released in 2009. It is infamous for letting the player use batarangs as throwable weapons against enemies, which caused the game to receive controversy. US Senator Hillary Clinton was one of the senators who wrote a letter to ESRB concerning their rating of the game as Mature, asking the ESRB to re-rate the game to AO, where they described it as "visceral and casually sadistic".
