Killer Rabbids (also known as Attack of the Killer Rabbids From Outer Space or Killer Freaks From Outer Space) was a cancelled prototype for a Rabbids title that was being developed for the Xbox 360.
At the Ubisoft Press Conference in 2010, it was announced that a shooter/horror survival game was in development. This game was originally going to be part of the Raving Rabbids franchise. It showed the Rabbids as more aggressive and disturbing than the original Rabbid design. However, since the Rabbids were targeted at younger audiences, the idea was scrapped and became Killer Freaks From Outer Space, later in 2012, the entire alien invasion premise was scrapped and was turned into a zombie survival game for the Wii U known as Zombi U
