Concept: a dungeon-crawling sci fi game, except instead of wandering space pirates, you play as a crew of legitimate salvage operators retrieving valuable goods from abandoned or evacuated cities on formerly populated planets that have been rendered uninhabitable by various civilisation-ending disasters. The different “dungeon types” would reflect whatever disaster killed that particular planet: plague, increasing solar intensity, nuclear war, continent-shattering meteor, etc. Long-dead worlds have already been picked over by your competitors, of course, so in most cases you’re going in while the world-ending catastrophe is recent – and in some cases still ongoing! – offering plenty of opportunities for potentially fatal misadventures. If you need an overarching plot, maybe you eventually discover that all of these apparently unrelated disasters have some sinister common thread.
A few of the odder fates that might befall a world, as well as salvage operators’ slang terms for such worlds:
- Deadworld: A world whose inhabitants have been rendered irretrievably non-sapient by a contagious neurological disease, parasitic fungus, basilisk meme, or other similar vector. Though in many cases their bodies are alive and kicking, they’ve been declared legally brain-dead, leaving the world open for salvage. Describing these unfortunate remnants as “zombies” is considered both unscientific and insensitive, which stops basically no-one. Sometimes an apparent deadworld turns out to actually be a nascent planetary-scale hive mind, which just gets awkward for everybody involved.
- Eight-Ball: A world that‘s experienced a hard-takeoff singularity, a sudden asymptotic acceleration of cultural and technological development that certain worlds undergo for reasons which remain unclear. Nobody’s 100% sure what happens to the inhabitants of such worlds; some believe they transform into beings of pure information, transcend to another dimension, or simply die off, their civilisation achieving its zenith, decline and extinction in a matter of hours. Whatever the truth may be, one thing’s for sure: they don’t need any of their stuff anymore. Eight-balls are highly sought after by salvage operators because of all the physics-defying Weird Shit the planet’s former owners tend to leave behind in the wake of their apotheosis, and are among the most dangerous assignments imaginable for the exact same reason.
- Locker: One of the oddest fates that can befall a world, a temporally locked civilisation – or “locker”, for short – is literally frozen in a single moment, usually as a result of some damn fool messing around with time travel. With fewer than a dozen known cases in the whole of galactic history, lockers present a unique salvage opportunity: the retrieval not of property, but of people. No means of reversing a temporal lock exists, so the world’s inhabitants must be rescued one at a time, by crews equipped with containment suits that allow them to move about in frozen time – a task frequently contracted out to established salvage operators. Lingering on such worlds is not recommended; though there’s no scientific proof of their existence, rumours persist that temporal locks are known to draw the attention of things that live sideways in time.
