English - From Dunwich to Innsmouth, from the halls of Miskatonic University to the Charles Dexter Ward at Arkham Asylum, trouble is in the air. The stars are almost right, and terrors from beyond space and time are beginning to break through. When Cthulhu rises, we're all doomed – but whose downfall will be the most entertaining?
