What started as a proof-of-concept mod had since turned into a full-blown project, where the goal was to get major dungeons, like Human Prisons and Apex Research Labs to name a few, to spawn in pretty much any layer imaginable, from the edge of space to deep into the planet's core!

Note that, due to spawning limitations within the game's engine, the diversity of dungeons was limited, so that, say, dungeons wouldn't generate in a way that they'd clip off of the top or bottom parts of the world. Thus, Avian Towers were kept from spawning in space, and naturally-subterranean dungeons like Floran Prisons and Glitch Sewers were prevented from spawning deep underground.
