Uranians

Uranians is a 1-player science fiction themed arcade game for multiple systems.

The player controls a ship at the bottom of the screen that moves laterally and fires vertically. An alien mothership flies atop the screen just out of the reach of the player's guns. Smaller enemy ships launch from the mothership, and the player must shoot them down. When all vessels of a certain type are destroyed the player moves to the next level. There are four different types of enemy ship movement. The alien mothership will intermittently drop a large bomb that destroys about ⅓ of the bottom of the screen, which the player must avoid. A satellite can appear at the top left or right corner, and will drop bombs until destroyed. The player starts with three lives.
