Galaxian — About this game
Move a fighter along the bottom of the screen and fire at the alien formation overhead. Enemies break away from the ranks to dive toward your ship, so watch their descent as well as the targets still above you. A clear shot at the formation can become dangerous when a diving enemy crosses your position. Shift along the lower edge, leave room to escape and clear the attackers to reach another wave.
