Alien Evil on the Dark Mountain, 1: The Norway Mission

Take a unit of assorted feckless squaddies hoping to see out the war in a safe posting in the wilds of Scotland; put them in the mountains of Norway in the Arctic Circle on what is allegedly a simple recon mission.
Mix in a powerful Shaman driven mad by some malevolent presence in these mountains, hard bitten SS troops, a crack Russian commando unit and the mission becomes much more dangerous as the squad quickly discover.
Throw into the pot strange magic, other dimensional entities and a thing of nightmares that wants to destroy the world and the challenge for this bunch of misfits becomes a near impossible task.
Will they succeed against the odds? Delve inside and see for yourself!
Set in WW2 in the harsh Norwegian Winter the success or failure of the mission could decide the fate of the war and even the future of mankind itself.
