A new app for Android and iPhone will see fitness fanatics 'chased' by hordes of brain-hungry zombies every time they go out for a run.
The Zombies, Run! app, which is currently seeking funding, will give you instructions through your headphones and encourage you to complete missions.
The action takes place during a continually evolving story, in which you play the role of "Runner 5" and are in charge of rebuilding society following a zombie Apocalypse. Each run is a new mission in that effort.
The app doesn't use augmented reality, (although that would be stupendously cool), it just encourages you to hit checkpoints, which count as 'picking up medical supplies.'
You'll hear the army of undead souls groaning in your ears, which if you're running at night, is sure to increase your minutes per mile. Missions last between 20 and 30 minutes and there will be 30 missions to complete in Season 1.
The idea is that every time you run, you'll encounter a new part of the story as users seek to rebuild the city and instructions will be delivered in between songs on your custom playlist.
The app will, of course, use GPS to let you know your distance, time and calories burned, while giving you that extra incentive to run more often and for longer.
The app is scheduled to launch for iPhone in February 2012, while an Android iteration will come in May. It's probably the most unique concept for a fitness app we've ever encountered so we're really keen to get our paws on this.
