The new Left 4 Dead 2 demo will drop in the early part of November, but anyone who pre-order'd this game should get the demo a week early, Valve announced today.

The Left 4 Dead 2 demo will only include gameplay from The Parish campaign, set in the New Orleans' French Quarter. The Left 4 Dead 2 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 game demo will also feature all of the new bosses and infected zombies, as well as melee weapons found in the full game.

The demo will be available to everyone else on Nov. 10. PC gamers and Xbox Live Gold members get to check the demo out starting Nov. 3 and people who pre-oder the game will get access to the demo on Oct. 27.

Left 4 Dead 2 will be hitting the PC and Xbox 360 on Nov. 17.
