Six words about zombie games

(I've had some medical problems that have distracted from writing about games lately, but this should be of interest.)

According to tweetdeck, one of the trending:worldwide topics on twitter not so long ago was 6 word stories.  In the past few months I've asked people to say 6 words about game design, programming, wargames, stories in games, casual games, and  innovation (and plagiarism) in games.

This time the challenge is this: say six (interesting or amusing) words about zombie games.
