Orbis
Description
Orbis is a 1-player arcade game for the VIC-20.
The player controls a target, and tries to shoot down the alien bombardment from above. The alien balls move rapidly horizontally at the top of the screen, and are randomly dropped towards the bases. The player has 5 bases that they must try to protect from alien attack, and if all are destroyed, it's game over. At the end of every round, the bases are restored.
