Situation Critical is an adventure seed contained in the Star Wars Gamemaster Screen. Alliance to Restore the Republic forces have set up a base on a planet with a hostile native species. The species steal vital components to the base's reactor core; the players must retrieve the parts before the reactor explodes in thirty hours. Gamemasters were encouraged to generate a custom planet and suitably primitive alien species. Possible alternate storylines that could be adapted by a gamemaster were also included. It was written by Bill Olmesdahl.
