Making the debris field a more of an adventure

[Zamujasa]

the problem with just adding new levels is that every new z-level is another 90,000 map squares the game has to manage; multiply that by a few to handle other components (lighting, etc) and you start to see why there are only a handful

i would like to see a terrestrial mining area (similar to the trench, but not underwater, or cave-based?) but i like the debris field as-is for hosting a lot of static content
