Doug Lombardi has told Joystiq that a multiplayer demo for Valve's Left 4 Dead 2 is planned for both the Xbox 360 and PC. According to Valve's PR guru, users who pre-order the upcoming zombie survival title at "participating retailers or [via] Steam" will gain "advanced access to the demo," which will eventually land on both platforms for all users prior to the game's November 17 launch.

Speaking with OXM at a recent London preview event, Lombardi discussed the strength of Left 4 Dead's "word of mouth," which has presumably fueled the need for a demo to the sequel. With groups calling for a boycott of Left 4 Dead 2 due to lack of content support for the original title, a demo may be the best way for Valve to prove why it believes its sequel warrants a full price tag. Although, strong pre-order numbers tell us the game is already on pace to decimate sales charts like a zombie tank.
