Left 4 Dead 2′s DLC known as “The Passing” will be coming out this Thursday April 22nd for the PC and Xbox 360. The DLC will feature a meet up between the Left 4 Dead 1 crew and the L4D2 crew in a small town in Georgia sometime after the Dead Center campaign.
The Passing will also deliver a new co-op challenge mode, support for infected bot play in Versus, a new “uncommon common” zombie class (the fallen survivor), golf club melee, and an M-60 to add to the many guns. You can download the DLC for 560 Microsoft Space Bucks, and free on the PC version. The Passing also introduces a series of weekly game mode events that will be known as “Mutations.” These week-long runs of new gameplay modes range from “Realism Versus” mode to “Chainsaw Massacre,” which gives all players chainsaws with an unlimited supply of gasoline. There are over 20 Mutations planned, each playable on all L4D2 Campaigns. Mutations are exclusively available to owners of The Passing DLC.
