According to an interview with Gabe Newell, managing director and co-founder of Valve, there will be a playable demo of Left 4 Dead, even before the release date which is momentarily set for world release on steam on Nov. 18, 2008 and in retail locations Nov. 19,2008 (U.S) and Nov. 21 2008 (UK)

The demo will contain both online and singleplayer mode and will contain the first two maps of the hospital campaign. The demo will only feature the survivor co-op side (no playing as boss infected). It is confirmed that the demo will come out for Xbox360 as well as for PC.
