Yeah but I don't believe Dead Ops is canon to the storyline, too many different ideas that aren't incorporated anywhere else, especially the Cosmic Silverback who is not mentioned or seen outside of Dead Ops, plus it's pretty much the only map in BO1 to not expand the story at all. I personally believe it's just a 'mini-game' of sorts and should not be regarded as canon to the storyline in anyway.
