Sony's "Ape Escape" apes make their way to the mobile phones with "kart" driving fun. Nine different circuits are available, featuring three types of surfaces, from tarmac (best with slicks) to rain/snow (best with wet tires) to dirt tracks (best with dirt tires). There are four apes, one has a balanced kart, the other three feature good brakes, good top speed, or good acceleration respectively.
You can race in the "grand prix" mode, which basically means you play one course after the other until you beat them all, with the other 3 apes on the track. The other mode is the "time trial", which means you're on the course alone (with a "ghost lap" of the fastest guy so far) and try to set fastest times. If you play the 3 advanced courses (the last 3 of 9) and set records, you can unlock additional tires and engines to further improve performance (which would allow you to set even MORE records!)
