Ratten!

A light-hearted roleplaying game set in a rat society inhabiting an abandoned warehouse known as the rat-castle. Players take the roles of human-like rats belonging to different clan-like groups, or Rotten, that occupy the warehouse’s departments. Although they resemble people in many ways, the rats remain rats: they do not walk upright, have thumbs, or cook. The group plays through adventures amid a fragile peace, with old clan rivalries and hatred threatening to return. Characters explore their dangerous surroundings, interact with other rats, and face the challenges of life in the warehouse.
