If you saw our previous story on Call of Duty: World at War's secret zombie mode, then you know this is going to be all kinds of awesome. But after getting our grubby little hands on the official trailer, well, this is going to be all kinds of awesome with a side of exploded zombie heads.
The trailer does a great job of showing you the absolute need to work cooperatively to stay alive as you are relentlessly assaulted by wave after wave of undead Nazi soldiers. Looks like Left 4 Dead has some competition from an unlikely source...not that Valve is worried.
The full trailer is embedded after the break, but I warn you, it's intended for mature audiences only. You must be 18 or older to read on.
