The Left 4 Dead 2 mutation for owners of "The Passing" DLC for the next week is "Headshot!". In this mode, only headshots and decapitations will drop enemy zombies.
"Shoot them in the arm, shoot them in the leg, shoot them in the chest - it just doesn't matter! The only way these zombies are going down is with a head shot. Other hits will stumble them back, but only a head shot or decapitation will kill them." This mutation is available for the campaign.
Additionally, a patch has been applied to the PC version of the game via Valve's Steam digital distribution service. The Xbox 360 version will eventually see these changes implemented.
Valve describes the changes on the Left 4 Dead Blog:
While not removing Defibrillators, we have made some changes to them
Simply narrowing the one hundred twenty eight images we received--located here and here--into twenty finalists was a tough task. The votes submitted by our panel of judged reflected how difficult it was to pick the five winners out of those twenty finalists--in fact, we had to call in additional "tie-breaker" judge.
So, without further ado, the winners (and prizes) of our Art Contest:
Players can now vote on which past mutation will return for an encore week. Your choices are Bleed Out, Follow the Liter and Last Gnome on Earth. The first mutation, Realism Versus, has already been made into a permanent game mode.
"The Passing" DLC is required to play mutations and vote in polls. It costs 560 MS Points ($7) on Xbox 360 and is free on PC.
Additionally, a new mutation has gone into effect today titled "Follow the Liter", which changes the rules to the Scavenge gameplay mode:
Only one group of cans spawn at a time, so survivors know exactly where to go. There is only one problem; the Infected know exactly where ...
This week, players can try out "Bleed Out":
Your health is a ticking away!
With constant mobs chasing you, there's no time for standing around. You have no permanent health, only temporary health that is continuously ticking away. You won't find any health packs to restore your health, only pills and adrenaline. This mutation is for Campaign mode.

Only one Mutation will be available at any given time, changing weekly. A monthly poll will allow players to vote on which Mutation they would like to return the following week.
