l4d-violenceValve released, as promised, the Crash Course DLC for Left 4 Dead – the second downloadable content pack that adds even more challenges for the fans of the shooter.

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.

Crash Course is completely free for download for computer users, so those who keep saying that PC gaming is dead (or dying) should take a look at Valve and their way of handling business.
