CarArena is an insane version of GTA Take out pedestrians to gain experience points and upgrade your car. Aim to dominate the leader board while trying to keep your health up.
Avoid crashing into buildings, but crash into pedestrians and other players at will except they are higher level players. You can gain a boost by hitting the space bar.
Your target is lower level players and pedestrians. Try to upgrade to more sophisticated cars while avoiding the big boys too.
