Greetings,

Supers is an extra for the Adventure System. It presents rules specific to a supers campaign that either modify, replace, or supplement those provided in the Adventure System and the Primer: Supers appendix. The extra includes a brief campaign setup, the Prometheus Legacy, and over two dozen fully developed and illustrated heroes and villains.
