From Introduction:
“High Alert!” is a Star Wars Roleplaying Game miniadventure for four player characters of any level, and it is usable in any era. Really more of a subadventure meant to be played as part of a larger adventure, “High Alert!” explores what happens when something goes wrong with a covert mission. The heroes have to use their wits and cunning to escape an enemy-controlled starport without attracting attention. It forces the heroes to put away their blasters and lightsabers and rely on stealth and guile—giving some of the less combat-oriented characters a chance to shine.
The Gamemaster can use this subadventure to fill in the details of an otherwise undeveloped part of other adventures: the part where the enemy becomes aware of the heroes’ actions and reacts by trying to capture or kill them. The enemy can be Separatist droid troops (if the campaign is set in the Rise of the Empire era), Imperial stormtroopers (if the campaign is set in the Rebellion or New Republic era), or Yuuzhan Vong warriors (if the campaign is set in The New Jedi Order era).
