Guardians of Sol
Players take the roles of high-tech law enforcement agents serving the Tetra-League and its military forces in a far-future science-fiction setting. Their assignments include hunting terrorists, pirates, hackers, and rogue soldiers; gathering intelligence; governing systems; protecting defense networks; and monitoring wormhole traffic. The game provides rules for investigation, combat, power armor, weapons, starships, character advancement, and large-scale military operations. Quick-and-dirty systems and guidance for running police-style adventures support referees. It is a stand-alone role-playing game that can also be adapted to other science-fiction systems.
