Just in time for Halloween, if you pre-purchased Left 4 Dead 2, you can have the demo by this Tuesday. For those that have already shelled out the money, you can begin to pre-load the demo now. Once Tuesday the 27th rolls around, you’ll be able to hit the ground running, axe in hand, and get a taste of that wonderfully gratuitous L4D2 zombieinfected living human gore.

If you preordered the demo at participating retailers, you should have received a demo pre-load code to get the goods. If you don’t have a code, contact the retailer for details. If said retailer is not participating in the program, then get a refund and buy on Steam.

The early access demo is being offered to PC and Xbox 360 customers. PS3 customers are once again denied, as there has been no definitive word on a PS3 release for the game.

The demo goes live for everyone on Tuesday, November 3rd.
