Think of it as a roleplaying game in which you are the dice, maybe. If you dive, jump, bounce, and roll right, you’ll escape the imaginary zombies coming for you. If not, you’re the dinner of the undead.
Wired magazine’s got a look at a full-body zombie-escape workout plan that uses your imagination to motivate you to new heights of aerobic action. It’s sort of like a parkour LARP in a safe, padded environment. The zombies exist only in the collective imagination-space of the athletes, and there doesn’t seem to be much of a story to speak of, except for the little micro-tales that form in each participant’s imagination surrounding this narrow escape or that daring feat.
Do these people know that they’re roleplaying? It doesn’t matter. They totally are.
