Want to get your hands on the Left 4 Dead 2 demo? If you're an Xbox 360 owner, you're in luck. If you're a PC gamer, you'll have to wait a bit longer.

"The Left 4 Dead 2 Xbox 360 Demo is now available for those who pre-ordered and obtained early access to the demo," says a short e-mail announcement sent out by Valve. "The PC Demo is currently targeted for release on Wednesday, October 28."

If you haven't pre-ordered the game, you'll need to wait even longer. Xbox Live Gold members and PC owners who haven't reserved the game will receive demo access on November 3rd. Xbox Live Silver members get it on November 10th.
