Yar's Revenge (Score 1)

And I quote: "In a distant galaxy the civilization known as the Yars were attacked by the fierce Qotiles. Though badly damaged, the Yars' fought back using their mechanical ships that look like giant metal insects. The Qotiles have many laser cannons shielded behind celluliod barriers which are capable of destroying the Yars. It's up to you to control your Yar ships and dig your way through the shields and fire your powerful Zorlon Cannon into the Qotiles."
