Even though initially boed by the fans and boycotted, Left 4 Dead 2 remains one of the most anticipated games to be released this year and everybody is excited that a demo will hit their computers and allow for some test driving. For those of you who wish to try the game before its full release, I have the full details about the Left 4 Dead 2 demo which is coming on October 27 or November 10 (earlier for those who pre-order).

According to Valve, the Left 4 Dead 2 demo will feature gameplay taken from “The Parish” campaign, set in the New Orleans French Quarter. Playable by 1 to 4 players over local or Internet connections, the demo features all the new boss infected zombies and all the new melee weapons included in the full product, so you’ll get a chance to try everything out at least once.

With the AI Director 2.0, L4D’s dynamic gameplay is taken to the next level by giving the Director the ability to procedurally change weather effects, world objects, and pathways in addition to tailoring the enemy population, effects, and sounds to match the players’ performance. The result is a unique game session custom fitted to provide a satisfying and uniquely challenging experience each time the game is played.

Adding new Survivors, boss zombies, weapons, and items, Left 4 Dead 2 offers a much larger game than the original, featuring more co-operative campaigns, more Versus campaigns, new Survival maps, and the new competitive game mode, Scavenge, all available at launch. Which is scheduled to take place on November 17.
