Valve tipped us off today to let us know that Turtle Rock Studios' latest game Left 4 Dead will be on hand at QuakeCon 2007, scheduled to go down August 2nd through the 5th in Dallas, Texas. The co-op shooter will be playable by attendees with Turtle Rock staffers on hand to help ease you into the world of freeing hordes of zombies from their reanimated corpses courtesy of high-powered firearms.

The four-player, first-person shooter is due to hit Xbox 360s and PCs in the fourth quarter of 2007. QuakeCon attendees will have a rare opportunity to go toe-to-toe with the game before it ships/is delayed to 2008. Way better than showering, for sure.
