Hello fellow Game Masters.
My year-long campaign is getting to the finale. The PCs are chasing the Bad Guy to the alien world, where he had found technology that almost helped him destroy the Galaxy (a force-based virus spread via hyperspace - hey it's Star Wars science ).
Before they confront the villain I'd like to have them a series of encounters, hopefully in a limited sandbox environment with the planet.
The planet is a ghost world, the race that inhabited it long gone (except for one survivor who actually guides the villain's actions). There are left some mechanical constructs, some slavemind-bound combat slaves etc.
The party (power level around 480xp) consists of a pilot, a stealth/survival expert, a slicer droid (who is crucial for the adventure) and a face (charm, deception etc).
I'd like to hear from you some ideas of cool adventures - one I came up with is that the droid, who is absoluttely non-combat PC, will be able to assemble combat upgrades around him, allowing him to rain death and destruction for a limited time.
