Really good scenario, and a strong starting point to a WW2 Cthulhu game. Whilst it isn't listed as being needed, a copy of "Weird War II" is extremely useful for fleshing out character generation options.
My only real grudge is that the handouts have "Achtung! Cthulhu" in the header of every other page, and are designed to be handed out at the mission onset, kind of ruining any hope of keeping the nature of the game a secret... At the very least the header could have been put into a different layer so I could hide it before printing.
