For those who pre-ordered Left 4 Dead 2 at your local Gamestop, the demo is now available for you on the Xbox Live Marketplace. The PC demo has a tagged release date for October 28th, which is believe it or not today! So, go download the demo and experience the next step for Left4Dead!

You’ll play as one of four new survivors armed with a wide and devastating array of classic and upgraded weapons. In addition to firearms, you’ll also get a chance to take out some aggression on infected with a variety of carnage-creating melee weapons, from chainsaws to axes and even the deadly frying pan.

You’ll be putting these weapons to the test against (or playing as in Versus) three horrific and formidable new Special Infected. You’ll also encounter five new “uncommon” common infected, including the terrifying Mudmen.
