Hypertron

Hypertron is a single player, keyboard controlled, sci-fi shooter.

The backstory is that in the future this is the must-play game for the rich folk on Titan. They enter an arena, stand in the centre, and see how long they can survive against waves of robots. Bonuses are scored for every five 'H' tokens the player collects, there are weapons power ups too.

Each level starts with the player in the middle of the arena surrounded by an increasing number of hovering robots who circle around and attack randomly and with increasing frequency. The object is to collect the tokens and powerups while blowing everything else to pieces
