Black Ops has another DLC coming out on the 23rd of August and it contains:
-All 4 World at War zombies maps.
-A new zombie map called MOON.
-A theme for 'MOON'
-A zombies soundtrack including 3 tracks never before avalible for purchase.
This is the final chapter to zombies so I hope its good. Sadly there is no multiplayer maps in this pack. 2 new Weapons for zombies are the Wave Gun which is for cooking zombies and a Quantum Entanglement Device which taps into the theories of Quantum mechanics to bless (or curse) your battle against the undead. There are new equiptment and perks for zombies.
For those who already have the World at War maps get this free including Moon, Soundtrack and theme. It is 1200 Microsoft points for every one else.
The following weekend is Double XP.
