Left 4 Dead is getting some new DLC, which means that although L4D2 is due out in November that there's still life left in the old horse yet.

Valve has announced a whole new single player and multiplayer campaign for both the XBOX 360 and PC versions of the game and it seems many XBOX 360 gamers may well be levvying more complaints towards Valve when they find out that they will have to pay 500MS points when PC gamers will get Crash Course for free.

Crash Course is set to add some continuity between the No Mercy and Death Toll campaigns from the original release as well as making a mockery of that helicopter rescue at the end of No Mercy as it seems that the helicopter won't be quite the flying whirlybird of salvation the game led us to believe the first time around.

Crash Course will add to the Survival and Co-op modes, not just as a new level but also by adding a recharge timer for infected teammates, and tweaked item spawning for a more balanced experience.

About the new release Gabe Newell said that "Since the release of Left 4 Dead last November, the design team has been excited about creating new experiences for this world and allowing players to do the same, by releasing much of our internal toolset, like the Survival Pack and Authoring Tools," He also added that "We're working with the fans toward the ongoing entertainment value of the product."

The DLC will be coming in September and is looking like it will not only be a good stopgap between now and the release of L4D2 but is also (in my opinion) bound to annoy and alienate many XBOX 360 owners who already pay for XBOX Live by charging for something PC gamers are getting for free and is almost certain to gain more names for that anti L4D2 petition.

On the other hand, it means we all get to shoot more zombies....and that's the main thing. Right?
