Right now at the Lightspeed web site you can down load a free PDF of the revised PSI Rangers rules for the Lightspeed game. Lightspeed: Psi Rangers requires Lightspeed to play, but can be used with Instant Lightspeed with little conversion. The older version of Psi Rangers, intended for use with Instant Lightspeed, is still available for free download. The new version has lots of cool artwork and all manner of cool stuff
