Breaking news: The upcoming ‘Survival Pack’ downloadable content for Left 4 Dead will be free for both PC and the Xbox 360. If you couldn’t figure that out from my cryptic post title, shame on you. Go away, and don’t come back til you’ve learned your TLAs.

Anyway. This is good news for 360 owners, who typically get stiffed with this sort of thing and have to shell out for any extra content for their games. It is also good news for Valve fanboys (such as myself) because the announcement shows that Valve have considerable weight behind their position, even when dealing with giants like Microsoft.
