Finding your motivation flagging since you first purchased your Nike+ FuelBand? Log onto NikeFuel Missions, the first game to use NikeFuel to unlock events and content when the user earns a specific amount. Each mission is played against the clock, with Nike athletes like Calvin Johnson, Allyson Felix, Alex Morgan and Neymar Jr. providing help along the way. Users can adjust difficulty levels and sync their Nike+ FuelBands -- or other Nike+ devices -- to track their progress. Missions can be replayed if users don't meet their goals. Check out an introductory video below, then head over to NikeFuel Missions to begin playing.
