Get fit and have fun? Also, Zombies!

Recently stumbled across a "game" called Zombies, Run!
Anyone seen and/or tried this? It looks like a way to make running more entertaining by including the concept of surviving Z-Day in with your run. The main game/app has several missions that include collecting items (not real ones, I believe), escaping from zombies by sprinting (interval training I guess), and some other activities.
It looks a bit pricey for what it is but if it could kick my lazy butt in gear and get me back to running again, it just might be the right thing....
