Be careful of the electric barriers. Try to time your
movements so that you do not get electrocuted. Once you get the Laser from the first blue block it
should be your main weapon. You can destroy things below where you shoot from which is simple
to see when you shoot at the Missile Turret from on top of the ramp that is under the bridge just
after the Laser. Even though it is clearly under you, it can still be shot without going down into the
Mines at the bottom of the ramp. If you and using the Heavy or Middle
rig you can shoot the Wakka from a long distance away without going over the small bumbs,
whereas the Light rig is not tall enough to shoot over the bumbs.
The last enemy, the Spinner, takes three laser shots to destroy, so don't waste your shots.
What you need to do is set-up your rig in the manner show above and try to drive up the ramp and land on the upper wall of the arena. From here you can drive around on the upper wall for fun.
