Temple Run Brave at $0.99
Temple Run Brave is just like the original Temple Run, which has been downloaded more than 80 million times, but with a few slight changes. It uses the heroine of the movie, Merida, instead of a generic adventurer, and the movie's giant bear Mordu as your attacker. Mordu is a great, evil-looking adversary, a Moby Dick-style force of nature with broken spears and arrows sticking out of his back. One look at him and you'll feel the urge to run, too.
