Left 4 Dead 2′s upcoming DLC, The Passing, will be released for the PC and Xbox 360 tomorrow, April 22nd. The add-on includes a new campaign, a new special-infected (the “Fallen Survivor”), and a rendezvous with the original game’s cast.
But equally as exciting is Valve’s announcement of a new feature that they are calling Mutations! Mutations are week-long sessions of unique game modes for players to enjoy, such as Realism Versus and Chainsaw Massacre. Valve has said that, for starters, there are at least twenty different modes planned for the Mutations program. Once again, Valve delivers something new and creative for their fans! Now, prepare to be eaten!
