I actually pre-ordered the game last night so I could get me some L4D demo, but now that’s no longer necessary. Fire up Steam and download all 3.2GB (!!!) of it, it’s super fun. Play it on Advanced and get your buns handed to you. I played a few rounds last night and when you lose, you feel like it’s your fault for not working together enough (or shooting each other a lot). Like Team Fortress 2, the team aspect is really stressed, and anyway who doesn’t love co-op?
Hopefully I’ll run into some of you guys, my name in game is >> so say hi if you see me.
