The ultra-violent Xbox 360 and PS3 game was just too much and so won't be releasing November 26th, unlike most other places on planet Earth.
Activision's Call of Duty: Black Ops even had to have a localised version for Germany because it rubbed too many German officials the wrong way. Namco Bandai I'm sure expected to have their Splatterhouse banned from sale in Germany, so no loss.
Splatterhouse releases on Xbox 360 and PS3 November 26th. What violence?
