Left 4 Dead 2′s The Passing to Include Gametype “Mutations”

Left 4 Dead 2′s The Passing DLC, due this Thursday for 560 MS points for the 360 or free for the PC, will also include another previously unmentioned perk, besides the new campaign, uncommon infected, and weapons: Mutations.

Mutations is a special set of gametypes that will, from week to week, be rotated out. These gametypes will consist of new ways to play, such as equipping the survivors with chainsaws with unlimited gas. Currently, there are more than 20different mutations already planned.

A lot of DLC comes through with nothing more than a new appearance, like Battlefield Bad Company 2′s new multiplayer skins due out tomorrow, but once again, Valve shows how to do DLC right: giving the players something worth the money.
