If you liked Left4Dead and MMO's, you'll probably get a kick out of this...

I'm playing a browser game called "Die2Nite" - a cooperative zombie survival game. Just browser-based, no cost/no download. You and 39 strangers get put into a town and have to survive as long as possible - it's a recipe for disaster (and there is no rescue coming, you just try and survive as long as possible) but seriously fun, it's pretty much all about communicate/cooperate or die. So far we've lost 12 people to the zombies, 1 guy is seriously wounded and won't survive till tomorrow if we don't happen to find some bandages (but he still made us some barbed wire to try and survive tonight's assault - bless him!), and one guy appears to have helped himself to more than his share of goodies from the town bank and locked it in his room (with a padlock which he also stole from the bank)....not a game I expect to play long-term (requires way too much cooperation which probably isn't realistic) but very entertaining
