Heading off any backlash that Left 4 Dead‘s upcoming DLC might have under-delivered with a promise to “simply” unlock the two remaining campaigns that aren’t currently playable in Versus mode (alongside it’s still not quite transparent Survival mode), Valve has just sent word that — like the continuing evolution of its Team Fortress 2 — the new modes will be free for both PC and Xbox 360.
First announced last week, the DLC will contain the extra multiplayer modes and that Survival mode which, to date, we only know will see your team struggling to survive as long as you can against a continual undead onslaught “across 12 maps.”
The spring release of the DLC will also see a new ‘Critic’s Choice’ retail package containing the original game and its new modes, and a PC SDK to let the mod community create new maps and custom game campaigns.
