Moonrider

The object of the game is to drive your moon buggy across the moon surface to complete the levels. You must jump over craters and small rocks and shoot the big rocks so you can continue. If that wasn't enough you have aliens above you, one shoots at you, the other throws bombs in front on you. If you get hit by the aliens or fall into a crater or hit one of the rocks you go back to the last restore point that you passed.
