Univaders

Eight saucers drift across the sky, each sweeping from one side to the other and slowly sinking. Your cannon ship on the ground moves left and right and fires a laser straight up: every saucer the beam touches is worth 10 points, and every saucer that sinks to the ground costs 10, though the score never drops below zero. A tumbling star-mine falls from the sky again and again, and if it strikes your ship you lose one of your four ships. Sitting under one column is no answer, since some mines start right above you. The game ends when the clock, counting down from 100,000 by tens over about two minutes, runs out, or when the last ship is lost. The high score is kept.

Controls: Controller 1 or 2: the stick moves the ship left and right, and either button fires. On the title, up and down choose and a button selects.
