Counter-Strike: Left 4 Dead Successor!

Somehow we ignored the fact that Valve and the team of Turtle Rock Studios developers officially announced the Left 4 Dead action, which will be based on the latest incarnation of the Source Engine and will include the second version of the Turtle AI technology.

The output of Left 4 Dead is scheduled for 2007, then it will be clear if this game will succeed the legendary Counter-Strike!
