The Plot according to Wiki:
The Terrornauts actually delivers quite a bit that can be used for any retrocloned science fantasy game.
Lets take the Star Talk Group themselves, this organization has the backing to become the UK twin of SGI from the Star Gate television series. If the modern upgrade works for Doctor Who it could potentially work for this group. They've got a network of "Transposer" plates that are the remains of an ancient stellar empire at their disposal.
The plot is the perfect set up for getting those Time Displaced characters into the interstellar action of Star Ships and Space Men Second edition. Then of course there's the mega-dungeon space station right in the middle of the picture with the robot straight out of X plorers.
Who knows what other potential treasures is on those "knowledge cubes" and lets not even get into that space fleet that's wreckage from the end of this picture.
I'm going to bet that you could see an entire series of adventures just spinning off of this film. The characters are recuited by a secret government organization to find, explore, and catalog the remains of this once great thriving interstellar race.
The Terrornauts remains a guilty pleasure after my fiancee from the UK showed it to me on VHS many years ago.
