It was recently made known that Valve is preparing to launch a $25 million Left 4 Dead 2 advertisement campaign in hopes of hyping up the zombie FPS. To put this into comparison, Vavle spent about $10 million on the ad campaign for the original Left 4 Dead, so you can see they are a bit more serious about its sequel.

The decision to put such a heavy chunk of change into L4D2 most likely came about after it was made known that it was pre-ordered a tremendous amount more than the original.

Expensive ad campaign or not, you’re still not going to be able to get your hands on Left 4 Dead 2 until its November 17th release date for the Xbox 360 and PC.
