Left 4 Dead: Crash Course DLC Now Available - Save 50% on Left 4 Dead

Crash Course delivers new single-player, multiplayer and co-operative gameplay and bridges the storyline between the No Mercy and Death Toll campaigns in the original game. To celebrate, we are offering Left 4 Dead at 50% off for 3 days. Or share the fun - get the Left 4 Dead Four Pack and give the game to your friends.

While containing both Survival maps and a Co-operative Campaign, the primary goal of Crash Course is to deliver a complete Versus mode experience in just 30 minutes, resulting in a streamlined version of the game's existing Versus campaigns.

Oooooh, now THAT'S the price I was waiting for! Between this, last weeks Jedi Knight pack, and the Monkey Island half price deal; Steam has been giving me unreasonable gaming for reasonable prices (btw, if you want to use that Steam it will cost you...blood...or money, whichever is easier for you)

And I paid 40$ for it. :( sadface

downloading the update now

The co op campaign is quite short (only two chapter)
It goes along with two new Survival maps.

Ok for a free DLC

It's also only 11,49€ for Europe. Really Cheap!!

bump for the glorious age of zombie shooting.

bump for last day for 50% off :O
