Valve have released the demo for their upcoming co-operative zombie survival FPS Left 4 Dead to pre-order customers, and according to 1UP will be opening it to everyone from the 11th November. Unusually, the demo’s multiplayer mode will be shut off when the game releases on the 18th, giving most players just one week to try it out. We’ll see if this experiment to prevent people sticking with the demo indefinitely causes grief or goes by without complaint; the reaction to the absence of multiplayer in the Multiwinia demo recently caused developers Introversion to relent and release a new online-enabled edition. It’s worth remembering that Valve typically have occasional free weekends for their multiplayer shooters, so other opportunities to evaluate the game should come up.
The Left 4 Dead demo is available on Steam, and the new Multiwinia demo can be downloaded from Introversion. We reviewed the original demo earlier, and found it interesting if not very deep.
