(adsbygoogle = window.adsbygoogle || []).push({}); Why are their so many gameplays of MP and not even a trailer of the zombie part so far?

People know what to expect from the multiplayer for the most part. They try and keep zombies more secretive.

I can't even remember if there was a trailer for Black Ops zombies...

Maybe they are saving it for a reveal during some upcoming event?

zombies is always the last information leaked for treyarch made games because it's the most anticipated part of there Call Of Duty ever since world at war due to the fact that some people play zombies that dont play multiplayer and almost everyone who plays multiplayer plays zombies
