Positron
Description
Positron is a 1-player arcade for multiple systems.
The ruthless invaders from NGC 891 are crashing through the ionosphere. The player must blast them before they reach the bottom of the screen, invading the Earth.
The player controls a laterally-moving ship at the bottom of the screen that fires vertically. Each level, the player encounters a number of alien enemies who return fire and move towards the bottom of the screen. If the player is hit or an alien passes them, then the level must be restarted. On level 8 an alien mothership appears, which must be destroyed to restart the game at a faster challenge. The player starts with three lives, and a new life is awarded every 100,000 points.
