You've landed your exploration crawler on the alien planet, and you're ready to look around... but all of a sudden, you're attacked by alien bug clones! And they're hungry for your battery power! Fortunately, some earlier visitor has left a supply of spare batteries and missile ammunition lying around on the planet surface, so you've at least got a fighting chance. Defend yourself with either missiles or lasers, and try to keep your batteries powered up as you fight the alien clones.
Controls: Mouse to aim and shoot; spacebar to toggle weapons.
