The villainous Dr. Corvid has evaded authorities, and sources state that his virus-like creatures have spread throughout the galaxy. Symptoms have been said to be heavy wind, spontaneous fireballs, electrical discharge, and dozens of other elemental ailments. The virballs are coming!

In Virballs, you play as ORB, a run-of-the-mill Object Removal Bot tasked with cleaning up the mess of the PopoBots. You see, when Dr. Corvid was intercepted by our inept-but-well-armed law enforcement robots, they carelessly shot down the mad scientist's over-loaded space freighter, scattering his latest fiendish creations across multiple planets. To make matters worse, innocent planetary inhabitants, Floobers, are being attacked by the vicious virballs.

The study of the biology of virballs is still in its infancy, but findings show that the organism shares much in common with viruses. In the field, virballs have been seen eating one another, which results in the manifestation of exotic hybrids. Presuming the mad doctor perished with the ship (spoilers: he didn't), the PopoBots called in the clean-up crew: YOU! The virballs must be cleared from every planet by any means necessary. On top of that, a handful of local civilians, Floobers, are having trouble evacuating and need your help getting to their ship.

Don't worry about accomplishing your mission; ORB comes equipped with rocket-propelled grappler claws, small thrusters to increase his mobility, and a containment sphere for special hazardous materials. Within this containment sphere, ORB can harness the powers of the virballs to create elemental Cores that allow him to grow his arsenal and thwart Dr. Corvid's plans.
