MadWorld is an ultraviolent beat 'em up video game developed by PlatinumGames and published by Sega for the Wii. Released in 2009, it is known for its distinctive black and white graphics with splashes of red blood, which contribute to its comic book aesthetic. Players control Jack, a participant in a violent game show called 'Death Watch,' and must use the environment and weapons to defeat enemies in creative ways. With its mature content, stylized violence, and dark humor, MadWorld stands out as one of the more adult-oriented titles on the Wii.
