When you achieve gold medals in: Crawler, Walker, Shuffler, Hopper, Jumper, Bounder, Runner and Sprinter, the new Hunter level(s) will become available. These are far more difficult than the others, and your opponent (Anti-Uni) uses some dirty tactics. Such tactic include; reversing your controls, making the track invisible and many other tricks. You automatically start with a Silver Medal there, so you are playing for Gold straight away!
