It seems that the zombie thing is particularly popular these days in the movie and video game industries.
I've been playing Die2Nite since it started, it's a neat little zombie survival game where you wake up in a town with 39 other survivors. You can play for yourself, or co-operatively with the others to make the town last - or a bit of both - or even better: pretend to do one whilst you're secretly doing the other
My name in Die2Nite is Workshop, say hello in case you come around and bump into me.
