A bomb explodes in Inverness station, and you're given a package that could save the world. To stay alive, you'll need to walk the length of the UK. The Walk is more than just a great pedometer/step counter -- it's a way to turn walking into a journey, a challenge, and a rip-roaring adventure.
Produced with the UK's Department of Health and NHS. Made by Six to Start and Naomi Alderman, creators of the world's most popular running game with over 750,000 players, Zombies, Run!
