Yesterday I pre ordered Valves latest, Zombie-tastic, duly awaited new game, Left 4 Dead on steam. And guess what I got? An early version of the demo. Frankly *puts on glasses beret and sips cappucino* I think its brilliant.
One thing that blew the socks off of my for head the first time I played is that the zombies are positioned in differently every game. So when I died and re-started I would get, mauled, sicked upon, and pinned at every corner.
Also I had great time trying to fend off the zombie apocalypse with my friends. Partly because it's one of those things that you just really want to do. You just feel so awesome 8)
Oh yes, and If you get the game don't trust doors. They don't last very long. At all.
EDIT: Oh yes I almost forgot, Thailand was awesome. ;) Met a very nice American girl there too.
