A report we missed last week on Official Xbox 360 Magazine indicates the release of Left 4 Dead 2 in November will be preceded by a playable demo (thanks Kotaku). "With Left 4 Dead in particular we've found that word of mouth really is the strongest thing," is how they quote Valve's Doug Lombardi. "With Left 4 Dead 2 we plan to do a demo before the game comes out that'll have multiplayer in it. And hopefully we can continue the free weekends with the full game post-launch." According to Joystiq, Lombardi tells them there will be advance access to the demo for customers who preorder the multiplayer zombie game through participating retailers or Steam.
