Demo

The Left 4 Dead demo was initially released on 6 November, 2008. It contains the first two chapters of the No Mercy campaign, playable in the Survivors' co-op mode, both locally and online. Initially, through a series of console commands, players could play as the Infected. This ability was removed in a 10 November, 2008 update.

The demo will be released to the public on 11 November, 2008. It is confirmed that the demo will come out for Xbox360 as well as for PC.
