On top of busting out the new "talking" Boomer plush toy, the Left 4 Dead 2 blog team also announced this week's Mutation: Bleed Out. According to the post, this mode essentially turns the survivors into milk jug with tiny holes in the bottom. As you play you'll steadily lose health. Precious health packs won't be available either, so you'll need to pop pills and shoot Adrenaline in order to survive.
If that sounds good, and you'll be around this weekend, you might be able to get into a match with the Valve crew. They'll be playing on both platforms. Their tags for both Steam and Xbox LIVE are listed below the fold.
