In competition against other well-established and popular superhero games, Superworld never found an audience, and was discontinued after only three supplements were published for it.

Superworld uses Chaosium's Basic Role-Playing system, with the addition of rules for super-powers.

Combat rules have many options and take into account three types of energy for damage: Kinetic, Electric, and Radiation.

The only rules that I have ever seen with anything like this in scope was the Golden Heroes FRP which may soon be available in a modified form from GW.
