It's finally happened... the zombie outbreak is HERE and the zombies are on the move. Your only hope for survival is to get active and outrun them!

THE OUTBREAK is a team-based activity game where your real-world steps and exercise allow you to stay ahead of a hungry horde of zombies that's chasing you through the remnants of your city.

Each week of the 6-week challenge, you and your team will race to a new safe house, trying to stay ahead of other teams and the zombie horde. But stay on your toes, the zombies who are chasing you aren't the only zombies you'll run into.

Obstacles and pockets of zombies line your path to each safe house, and you'll have to be strategic about spending your steps (earned by walking/running in real-life) and Power (earned by exercising in real-life) or saving them for an opportune moment.

You'll start the challenge as a human, but if you fail to stay ahead of the zombie horde you risk turning into a zombie yourself... at which point your steps and exercise help the zombies move faster and do more damage. Will you survive, or will you make sure no one else does?

-Sync your steps and exercise from Fitbit, Apple Watch or Healthkit*
-Form a team and get active**
-Use your real-world steps to move your team
-Use your real-world exercise to battle zombies
-Keep track of your progress on the level maps and leaderboards

Worked for 5 days, then....

This worked perfectly fine for 5 days. It synced my steps and my team was advancing with my help. On day 6 it worked for about 3 hours then logged me out for some reason. I tried logging back in but now it doesn’t recognize my password. Tried many, many times with slightly different passwords then tried using the “forgot password” link. It recognized my email, so I know I’m in the system (I hope) however it’s been 8 hours and at least 12 times of clicking that link and I have not received the email to reset my password. I’ve also emailed support 3 times and no response. I suppose their IT and their password support only works 8am to 4pm Monday through Friday. :-(

Got me moving!

Shame to see so many people rating this poorly because they’re unhappy that their colleagues are cheaters... that’s not the developers’ fault.

Personally, I had a lot of fun with this! Definitely got me thinking more about moving, especially after work when I’d see that we have another couple thousand steps to meet our team goal for the day. Liked the step bank that lets you roll over steps you accumulate until you “spend” them, but wish there was a clearer way to keep track of what steps were synced from what day.

Overall really great experience. When it ended I felt like something was “missing” in my day. Hope my company does this again soon!

Nice concept but poorly developed; watch out for battery killer

Still a good idea that hopefully someone can properly execute. HUGE battery drain. Definitely buggy, for example if you get to zero on power you can’t earn any more. Best to use a separate device to record your activity and only go to the app for very brief periods to record your activity. Turn off all background activity for the app, too.
