Played two rounds of the demo. One with real people and the second with AI. The game is very well made. Graphics are awesome and the zombies are refreshing.

First round I somehow started a server and some people joined (am I actually hosting?). Maybe it's because we're all new but the other 3 were really gung ho. You don't just run into a room with a crap load of zombies. Played it on easy and we beat it easily.

Second round I had to play with the AI since my connection had dropped. There I played on Normal. Since the AI follows you, I was able to be a bit more tactful. Used the handgun since it has a lot of ammo (not unlimited during the first half of the demo). Got to the door way and start knocking off zombies you see in site. If you're not in the middle of the room or in the street they won't come at you in droves. Takes a bit of fun out of it without all the frantic shooting but you've got to do it to win. Playing with people you know should be easier, especially coming from a team oriented game (TF2).

One thing I do dislike is the lack of comm. A game like that I think it's needed. Other than that I like it. I'll buy it as soon as I can scrounge up some money.
