Incursion

Incursion is a science fiction role playing game created by Richard Tucholka and published by Tri Tac Games in 1992. The player characters are humans abducted by alien slave traders. Together with other, extraterrestrial, slaves, they turn on their captors and kill them. During the fight, the vital navigational records are destroyed, leaving the ex-slaves kind of stranded; they are in possession of one of the fastest and most powerful spaceships, the Anshani space tug Ardanna Nuu, but they do not know how to reach their home worlds, since they all come from non-spacefaring planets in the backwaters of the galaxy that do not turn up in other spacefarers' logs.

Incursion is technically set in the same universe as Bureau 13: Stalking the Night Fantastic, but places the player characters adrift in a complex society, rife with politics and people after them for their ship.
