I honestly wasn't a huge fan of the zombies portion of Black Ops because games without an end just don't interest me, but the multiplayer aspect of an objective game involving zombies does. Zombies is a fundamental key to Treyarchs COD games and it would be great if it was implemented as an objective based game in the multiplayer community. This can include a multitude of different types: TDM, Vaccine Control Points, Kill Confirmed, etc. I'm sure the developers can come up with better game concepts than I, but including zombies inside the multiplayer game modes would be something new and exciting.
