An exercise in sprite creation, this one. Various different sprites, probably harassed refugees from other games, drift in from the top of the screen. Funny faces, birds, spaceships, that kind of thing. Unluckily for them there's the usual laser base/spaceship spitting hi-tech death hanging around. Out of sheer desperation, they split into two when you hit them.
Joystick control right/left/up/down, fire button controls laser. If the player possesses dogged tenacity and high boredom threshold, special twin lasers are awarded in frame 24. The Hall of Fame involves a deeply authentic and primitive procedure of using the joystick and Fire button to choose each and every single letter of a name. Yawn.
