A while ago, there was a patch for one of the most known games for the iPhone, Temple Run. There was originally a glitch where if you turn you character around, he will infinitely run without running into obstacles. This was patched, but they turned it into an achievement.
|The Glitch (Achievement)||Play the tutorial, when you come to your first turn, swiftly swipe your runner to the right by swiping the screen twice. Your charecter will turn around, and you will get the achievement. But you will no longer be able to continuously run without having to stop.|
