This week's Left 4 Dead 2 mutation is a very unique, and very co-op friendly one. Called Last Gnome on Earth, players are tasked with carrying a gnome through one level of the campaign. Sounds similar to the "Guardin' Gnome" achievement where you need to carry the gnome through the entire Dark Carnival campaign, but there's a twist.
Do you crave attention? Want all the infected to swarm you and the gnome you are carrying? Then we have the game mode for you. The team needs to carry the garden gnome from start to finish in any campaign. The common infected hate the gnome and will swarm whoever is carrying him. Watch out putting him on the ground, a boomer explosion will send him flying!
The mutation will be available for one week for owners of "The Passing" DLC. Valve will be playing online on both the Xbox 360 and PC, and you can see the tags they are playing under at the official blog.
