Le Rocher du Diable

The Devil's Rock: British Commandos, an SS Occult Unit in search of the ultimate Supernatural Weapon, Witchcraft, a shape shifting Demon. Yes, the Channel Isles were a fun place to be during WW2.

Two commandos land by dinghy on a decoy mission to sabotage gun emplacements thereby misleading the Germans as to the likely D-Day invasion sites. But they hear female screams coming from a bunker investigating they find a Lovecraftian scene, half eaten German soldiers, a soldier who has committed suicide. A Grimoire lies on the ground.

A surviving SS officer kills one commando and captures the other. Then we encounter the Demon who handily can take on the features of your loved ones. A summoning has gone wrong. The commando and SS officer are forced to cooperate.

Great Demon, ripping heads off.
