With the Left 4 Dead 2 demo coming to everyone November 10 on both Xbox 360 and PC, Valve has just announced that users will be able to get their hands on the demo on October 27 just by pre-ordering the game.

The Left 4 Dead 2 demo will include gameplay from The Parish campaign, set in the New Orleans’ French Quarter. The demo will let one to four players game together online or locally on both the Xbox 360 and PC versions. The Xbox 360 version of the game will include split-screen mode. The demo will also feature all of the new boss infected zombies and melee weapons found in the full game. -  KOTAKU

With Left 4 Dead 2 offering what we would consider an overall better experience than the first game, this early copy of the demo is definitely worth it for Left 4 Dead 2 enthusiasts.
