Left 4 Dead Survival Pack will be free to all

Zombie lovers/haters rejoice! The recently-announced Survival Pack DLC will be absolutely free of charge to Xbox 360 and PC gamers alike, confirms Valve.

As we reported earlier this week, this completely gratis content will allow players to battle each other on Versus mode on both the Dead Air and Death Toll campaigns, as well as introducing a brand new Survival mode.

PC gamers will also get free access the Source Software Development Kit enabling them to create custom Left 4 Dead campaigns themselves. If for some reason (madness, perhaps?) you haven’t picked up Left 4 Dead yet on any platform, you can always wait for the Critic’s Choice edition of the game which will be released along the DLC and includes the original game plus all bonus downloadable content.
