Valve Explains Left 4 Dead 2′s Speedy Appearance

Joystiq has spoken to Valve’s Chet Faliszek about Left 4 Dead 2′s appearance less than a year after the original. Chet tells of how Left 4 Dead 1 was broken in Valve’s eyes and wasn’t the right game to build off of. Left 4 Dead 2′s improved A.I Director will allow Valve to expand the game easily with DLC and updates. Nothing is planned as of now but L4D2 is meant to be the stepping stone in the Left 4 Dead series. So don’t expect any more DLC for your copies of Left 4 Dead. Left 4 Dead 2 is coming to Xbox 360 and PC November 17th.
