Robo13

Robo13 is a Robotron 2084-inspired twin-stick arena shooter. In the year 20XX a greedy conglomerate has developed mutant clones, but the mutants have run amok and taken over the company building. The Robo13 program is initiated to enhance human volunteers with cybernetics and send them into the overrun facility in order to prevent the mutants from spreading into the world.

The player can move and shoot freely in 360 degrees using twin-stick controls, and also roll to get out of tight spots.

Destroyed enemies might leave behind colored orbs that provide weapons and power-ups, some time-limited while others are only dropped upon death.
