A near-future semi-apocalyptic game set in a world where the sun never shines and the people have all gone insane: "Paranoids. Sociopaths. Pyros. Kleptos. Delusionals. They're all here -- and you're one of them. Welcome to the world of Asylum, where the United States has been reduced to a collection of walled Wards, built from former cities and surrounded by desolate Wastelands. The sun has been gone for over a hundred years, hidden from view by airborne algae called Blanket Seed, and everyone has gone mad."
