Cult of the Dead is the new DLC that has just been announced for Kalypso's action stealth title, Dark. The new mission is set to be released on PC on December 5, with an Xbox 360 version set to follow thereafter. In the new mission Eric Bane will be hunting for the ‘Book of the Dead', fighting against a new enemy type and a new boss, and there's also going to be five new maps in the game's challenge mode.
