Does your regular cardio workout seem too mundane for you? Zombies, Run! hopes to solve that by adding a little imagination to your run. You are a survivor in a post-apocalyptic world overrun with Zombies and the goal of the game is to collect supplies, rebuild your city, avoid zombies and just maybe... go from a couch to 5K type runner.
They were funded through a Kickstarter campaign and exceeded their funding goal. The project is well underway (already in beta) and they hope for a February release.
Zombies, Run! records the distance, time, pace, and calories burned for all of your runs (It also works on treadmills) and will even sync with RunKeeper.
Looks like fun! Watch out for traffic and don't get eaten!
