Cthulhu Britanica London: World War Cthulhu

London 1941. The blackout reigns. Only the burning bombed-out buildings and raking searchlights defy the War Office order that has cast the city into darkness.
The nightly rain of German bombs brings death and destruction to the capital. By day you try not to talk about the looming threat of invasion and how you miss having a belly full of real food. At night you huddle in the Tube and sing songs to distract you from the inky darkness.
But there are far more terrifying threats in that darkness than mere German bombs: twisted and ancient forms released from their long-forgotten prisons; inhuman scavengers drawn by the carnage to feast; depraved cults with demented plans to take advantage of the chaos...
