Perimeter Breach Detected

This planet is no place for humans. It has no name - only a serial number, buried deep in the logs of navigational computers. This is a deeply hostile world, covered in caustic oceans and jungles of blood-sucking plants. Its native lifeforms devour everything they meet. You should never have come here.

Experience a unique tabletop horror experience with Perimeter Breach Detected: part boardgame, part RPG, and 100% blood-splattered chaos.

Based on Bar the Windows, Bolt the Doors, this complete ruleset includes everything you need to descend to the howling depths of an alien planet. Team up (or not!) with your fellow players to try and survive a number of rounds inside a derelict outpost, while an unknown monster stalks you through the corridors. 

With easy-to-learn mechanics, simple set up, and without the need for a Game Master, Perimeter Breach Detected is the perfect pick-up-and-play game for horror party nights.
