Space Beam

In this early game from Irem, the player guides their ship left or right using a two-directional joystick, and they must destroy their opponent at the top of the screen with their equipped laser. Your opponent is doing the same thing. Separating the both of you are numerous rows of space debris which try to block your shots. Both of you have separate fuel gauges (labeled FUEL 1 and FUEL 2, respectively) that determine how far the laser can reach. If one of the gauges reach 100%, the laser will reach the top of the screen. If it is not, then the laser only reaches halfway toward the center of the screen. Once your opponent is destroyed, they are resurrected after a few seconds. The current pattern ends when your opponent is killed and all the space debris is cleared.
