Operation Darkness is a tactical role-playing game for the Xbox 360 developed and published by Japanese studio Success on October 11, 2007 in Japan.

The story covers much of the real history of the European war, including the battles for North Africa and the liberation of mainland Europe.

The game diverges significantly from real history in that zombies of deceased Nazi soldiers appear as adversaries, and two of the player characters can transform into werewolves.

[citation needed] Battles play out in standard tactical role-playing game (RPG) fashion, with turn order based on characters' speed statistics.

[4] Characters possess the following attributes: HP, MS (martial spirit), Attack, Defense, Speed, Hit, Luck, Weight, and Move.
