Usain Bolt, the world record holder for the 100- and 200-meter sprint, is now available as a limited-time in-app purchase in Temple Run 2. The sprinter comes with a special "Bolt" ability. Activating the special ability makes Usain invincible, turns on auto-guidance, and also adds a coin magnet. It's pretty bizarre to see such a recognizable figure rendered within a cartoon world, but this is certainly one of the more interesting in-app purchases we've come across. Of course, Bolt's no stranger to lending his visage to companies: he's the star of many commercials, including a long-running campaign for UK broadband company Virgin Media.
