Overnight Valve have released the Left 4 Dead demo to everyone, so whether you've pre-ordered or not, you can get stuck right into slaying some zombies.  So if you haven't already, fire up your steam client and you should see the Left 4 Dead demo in your available games list.

Due to the matchmaking system, by default you can't select which server to join.  You can access a server browser (even though its a bit buggy and doesn't show up all of the servers) and select which server to join.  I've posted details on how to do this on our forums here.

We've had a bunch of servers (64) for it up since the demo was released last week, so plenty of Freezone free traffic gaming to be had for iiNet and Westnet customers.
