Zombies, Run! is a running game & audio adventure iOS/Android, in which you help rebuild civilisation after a zombie apocalypse by actually running in the real world. You have to collect medicine, ammo, batteries and spare parts, while on occasion being chased by zombies. Now, this could easily be modified into a “Sharks, Swim!” game, me thinks, and the interest is there … they’ve had way more pledged on Kickstarter than what they originally aimed for.
Zombies, Run! will kickstart your interval training for sure
