From the introduction: The Strider Incident is designed for use with STAR TREK: The Role Playing Game as well as the STAR TREK Starship Tactical Combat Simulator. The Klingons supplement and the Klingon Intelligence Briefing, also from FASA, may prove useful, too. Up to six players can play this scenario, each representing a department head on the USS Lexington, an Enterprise Class cruiser. As written, The Strider Incident assumes that the ship's captain is an NPC, but the gamemaster may modify that if he wishes to allow a player to roleplay Captain Franklin.
