Valve today announced release plans for the Left 4 Dead 2 demo, revealing that those who pre-order the game from retailers or Steam will get it first, on October 27. Looks like the Left 4 Dead 2 boycotters ended their lil’ foot-stomping session just in time.

It’s due to be set in “The Parish” campaign, and will even support four players online or via local play. That’s how you do a demo.

If you forget to pre-order the game, then you’ll be able to try your hand at zombie-slaughterin’ a week later on November 3, so long as you’re a Xbox Live Gold member. Impoverished non-Gold subscribers will be left waiting until November 10, with the full game due on November 17.

And I can’t bloody wait.
