Situation Critical is an adventure idea featured within the Star Wars Gamemaster Screen. A base belonging to the Alliance to Restore the Republic has been established on a planet inhabited by a dangerous, indigenous species. These natives abscond with crucial pieces of the base's reactor core, and the player characters are tasked with recovering them before the reactor detonates in thirty hours. Game leaders were prompted to create their own planet and appropriately underdeveloped alien race. The adventure also offered alternative plot lines for gamemasters to modify.
