Dev Imangi Studios announced it's signed up Jamaican sprint star Usain bolt to be a playable character in Temple Run 2, probably the biggest proof yet beyond hard figures that Temple Run is a completely massive thing. The world's fastest man and Olympic gold factory is available now as an in-app purchase of 99 cents, but only for a limited time.

Of course, being Usain Bolt, he has a unique power-up that combines the speed boost with the coin magnet; we're not sure there's a better analogy for his lucrative life. Meanwhile, Temple Run 2 has been a similarly lucrative record breaker for Imangi, taking just 13 days to become the fastest-ever mobile game to reach 50 million downloads.
