Valve Software's Gabe Newell took the stage at EA's E3 press conference to present the cooperative horror game Left 4 Dead. We have the video of that presentation on the other side of the jump, but here are the Cliff's Notes.

All four current player character models will be replaced with the above-pictured folks. This was probably a good change; the old ones weren't very likable or varied. In addition to that bit of info, Newell talked about the game's AI director, which will adjust the gameplay to match players' playstyles, positions, and status.

He also said the game is coming out on November 4th, but that news ain't new. Anyway, the game seems to be coming along swimmingly. Be sure and check out the video after the break!
