Space King

Space King was produced by Konami in 1978.

Move your tank back and forth along the bottom of the screen and shoot endless waves of aliens marching towards earth. Shoot the flying saucer for extra points.

Move your base left or right to shoot the endless waves of aliens marching towards earth. There are four buildings (shields) that you can hide behind, but eventually they will be destroyed either by enemy missiles or by the enemies themselves. The aliens’ descent quickens as you eliminate them. Shoot the flying saucer for extra points.

The game is very similar to Space Invaders. The game is built on Konami 8080 arcade hardware. Gameplay is mostly identical to Space Invaders with some subtle differences such as Japanese score text on screen, more detailed graphics for the player and the four bunkers and adjusted graphics for the aliens.
