Procyon Warrior

Procyon Warrior is an early science-fiction themed 1-player game for the Apple II.

You are under attack by the spaceship Unterpriz, as well as its army of drone fighters. You must destroy all the enemy vessels before your own forces are defeated. The player controls a large and a small rocket independently, and both rockets can move left and right. The large rocket can be used only once, and the smaller rocket an infinite number of times. During each level, the player must use their small rocket to blast oncoming alien drones. After all drones are destroyed, the spaceship Unterpriz will appear. This can only be destroyed by the larger rocket. When all ships are destroyed, the player progresses to a more difficult level.

If both rockets are destroyed, it is game over.
