Moon Patrol

'Hop into your Moon Buggy. You're about to journey across the surface of the moon. Be prepared to blast moon rocks and jump over gaping craters and dangerous land mines. Then the real challenge begins: Three types of alien UFOs bombard your Moon Buggy. Protect yourself by firing missiles above and in front of you while jumping over huge holes and zapping lunar rocks and UFOs.'

Decent variation, but not very exciting gameplay.
