Just in case GameStop's Left 4 Dead 2 commercial was a little too slow-paced for you, Valve has released a new TV spot that's nothing but action. Of course, that action is culled entirely from the CG trailer that was leaked last month, so you won't see anything new here. You will hear something new, however, as the commercial has been injected with a thumping blues-rock soundtrack, making the whole thing feel like a big, sprawling, undead bar fight.
Come to think of it, it sounds like Joystiq Publishing just found its next game. No one has the rights to Undead Bar Fight, right? While we go do a little research, watch the trailer above and, after the break, watch G4's walkthroughs of the Scavenge and Survival modes.
