User summary Ace of Aces contains two Space Gothic adventures: Ace of Aces gives the characters the "opportunity" to explore a black hole as test pilots for a new space fighter prototype. The discovery of an old Shark Investment spacecraft presents additional dangers. In SS Collector the characters are transferred to a garbage freighter for disciplinary reasons. The smelly and boring work is interrupted by the need to blow up a rogue asteroid that threatens to crash into the space station the characters use as a base of operations. Hidden in the debris is an unexpected danger.
