Superpowered!

Superpowered! is a lightweight, 2d6-based role-playing game that allows players to play these superpowered heroes, with highly varied powers, as they work to keep their city, country, world, and the universe safe from the evil plots of those who would destroy all that is right and good. Superpowered! is based on the Quantum Engine and is thus compatible with Stellagama Publishing's Cepheus Atom post-apocalyptic rules, Barbaric! sword & sorcery rules, and Quantum Starfarer space-opera rules. - from the publisher's blurb
