If you're anticipating the launch of Left 4 Dead's sequel, you may be interested in participating in Valve's preorder promotion. Those who buy the game prior to launch will receive a 10% discount on the title, early access to the Left 4 Dead 2 demo, as well as a bonus in-game item.

First word of the Left 4 Dead 2 demo came less than two weeks ago, and it is slated for an October 27 release if all goes well. In addition to the demo and discount, preorder customers will be given an exclusive in-game baseball bat, which is one of the new melee weapons featured in Left 4 Dead 2.

At 10% off, the stand-alone title is priced at $44.99, or you can get three friends in on the action for $134.99. Also listed is a bundle that includes the original Left 4 Dead, and Left 4 Dead 2 for $64.98.
