Fans of iOS endless-runner Sonic Dash now have the opportunity to unlock moody gun-toting jerk Shadow the Hedgehog.
But only if they do 100 laps of the planet.
Not literally, mind. In the game, I mean. And not individually, either.
You see, Sonic Dash now features a global challenge, where all players work together in an attempt to unlock special rewards.
If all players can do 100 laps of the planet, cumulatively, before August 5th, then all participating players will get Shadow as a playable character for free. There will also be rewards granted when 25, 50, and 75 percent of that target is hit.
We gave Sonic Dash a Bronze Award at launch, and these words fell out of our collective mouth: "A perfectly playable endless-runner, Sonic Dash is entertaining enough, but highlights how far the series has come since its glory days."
Oh, and if you were curious, 100 laps of the planet is a distance of about 637,400km. No sweat, right?
The latest update to Sonic Dash is out now on iOS.
