First i would like to say how much i love playing zombies & so do all my friends. The mysterious story to the zombies side of call of duty is great & has a great mysterious feel about it, the different space guns/devices & the perks on different maps are amazing & make it endless fun. Since i bought black ops every time i load the game its always zombies i play before multiplayer & i also love multiplayer too . My top 3 maps are ascension, moon & kino der toten, the characters are really funny & add some humour to the game . Can't wait for black ops 2 to be released, i will be one of those pre-ordering it.
As for suggestions, there aren't really any other than it would be great if it could be updated with a theatre mode maybe?
