The Laundry RPG Core Rules

There are things out there, in the weirder reaches of space-time where reality is an optional extra. Al-hazred glimpsed them, John Dee summoned them, H.P. Lovecraft wrote about them, and Alan Turing mapped the paths from our universe to theirs.

The right calculation can call up entities from other, older universes, or invoke their powers... and that's where the Laundry comes in! utilizing the basic roleplaying system and based on the Laundry Files series (The Atrocity Archives, The Jennifer Morgue, the Fuller Memorandum) by award-winning author Charles Stross, players in the Laundry pose as members of a branch of the british secret service tasked to prevent hideous alien gods from wiping out all life on earth!
