For now, the only way to get the World at War maps in Black Ops is when you buy the Hardened and Prestige editions of the game. There has been no official announcement that the World at War maps will be released for sale to everyone in Black Ops, however Activision has never missed a chance to make some extra money, and this would certainly do the job.When will we be able to get the old zombie maps on Black Ops?
Only available if you purchased the Prestige edition of the game, and I think the Harden edition has it as well.When will we be able to get the old zombie maps on Black Ops?
