Ok, I'll just say up front that I hated Call of Duty: Black Ops' campaign mode pretty fiercely. This is for one rather absurd, if forgivable reason. I don't like anachronism in games that are supposed to have taken place in a non-alternate reality Earth past. It's pretty nit-picky, but having an M16 with multiple attachments at the Bay of Pigs, or a DPM with a holosight at a 60s era Siberian Gulag really chaps my posterior.
On the flip side, I think Zombies is one of the greatest game modes ever. It takes all the things I love about Firefight mode from Halo, adds interesting characters and more weapons, and stirs in a pulp era zombie romp. Sounds like a recipe for win if ever there was one right?
