About Der Riese
Der Riese (“The Giant”) closed out World at War's zombies in 2009. Set in a Group 935 factory, it introduced teleporters and the Pack-a-Punch machine that upgrades your weapons, and its story set up everything that followed. Black Ops remade it in 2011 for the Rezurrection map pack.
