This is a great comedy with Woody Harrelson, but if you want a taste of what it might really be like to walk among the living dead (apart from visiting one of the country's many Spa Towns) then there are bags of games featuring the peckish undead you can play on PC, such as Left 4 Dead, STALKER, Shade and Hell Forces, to name a few. There can be no guilt in blowing a zombie's head off, but a good game will allow you to get in on the action without any danger of being eaten alive yourself.
"Hell Forces"... meet your chums for num-nums
