i can see how this is a great marketing ploy ..... just search google for 'map pack 4' and theres so many people interested in it. Treyarch have us eating out the palms of their hands! All I can say is that they had better release the full zombie game before we all go off the boil!!!!!
(lol tho ... it sort of reminds me of the south park where cartman gets a theme park and advertises the fact that nobody can go there ... which just makes everyone really want to go!!!)
It is a bit annoying that they don't just tell us! A week ago I was WELL excited @ the prospect of new zombie content .... now tho .. I'm just a bit pissed off with them!
