Valve had promised the demo for Left 4 Dead for early November, but it appears that those who pre-order the game from GameStop will get in on the fun earlier.

The game’s product page on GameStop promises “early access to the demo” from November 6 to 11 for those who reserve a copy of the game. In fact, those who have already reserved it can go to this page to get their access keys.

While no release date has been provided yet, speculation suggests that the demo will be available to the general public starting November 12. The full game is due out November 18 on PC and Xbox 360.
