In this fun racing game your goal is either to win the race or to eliminate your opponents, in order to pass to the next racetrack. If you win, you earn money, that you can spend on upgrades or new parts for your car. These parts make your car heavier and slower, so think carefully about what you really need. There's a maximum number of upgrades per car. The question mark at the top of the screen can give you some extra information, should something not be clear yet.
Use the arrow keys to steer your car. Q = previous weapon, E = next weapon. A = nitro, S = fire, D = fire secondary weapon.
