Positive ID

From Introduction:

“Positive ID” is a Star Wars Roleplaying Game mini-adventure for four player characters of 6th level, though it can be adjusted for heroes of any level. It is designed for use in the Rebellion Era, but it can easily be adapted to the Rise of the Empire period or The New Jedi Order Era. “Positive ID” puts the heroes in the middle of a Nar Shaddaa nightclub stuffed full of all manner of aliens from the Ultimate Alien Anthology. When something goes wrong, the heroes will need their combat prowess to get clear, but a good Spot check and Knowledge (alien species) is vital, as well.

To play this adventure, you need a copy of the Star Wars Roleplaying Game: Revised Core Rulebook and the Ultimate Alien Anthology sourcebook.
