Biomes.
Every biome catalogued in Rogue Core. Each cave system carries its own hazards, terrain materials, enemy variants, and ambient lighting. Pick your dive.
Crystalline Caverns
Among the most spectacular sights on Hoxxes, the aptly-named Crystalline Caverns are truly a sight to behold. Massive crystals erupt from every surface, glittering and twinkling in the dark. Alas, the larger crystals are mostly worthless silicate, but abundant deposits of valuable minerals dot the caves too.
Fungus Bogs
We’re almost sorry to send employees in here, but the rewards are just too great to ignore. So therefore: Welcome to the Fungus Bogs! A truly awful region, built mostly from slime, mold, stinging insects, fungus, stinking mud, and corrosive lichen.
Glacial Strata
At least one of our xenogeologists quit in a rage when research started on this region. Instead of having conventional polar ice caps, and in violation of all physical laws we know of, the continental plates of Hoxxes rest on top of a planetwide permafrost layer several miles deep. As always, DRG recommends a “don’t ask” approach when dealing with the peculiarities of Hoxxes’ makeup.
Dense Biozone
Whoever said plant life needs access to sunlight has obviously never visited Hoxxes. This region is dominated by what can best be described as a subterranean rainforest - masses of writhing, (mostly carnivorous) plant life, producing entire microcosms of life deep within the crust of the planet. Tread with care.
Magma Core
Among the deepest of our mining sites, the Magma Caves are a mellow 250-400 degrees and helpfully lit by the churning, molten innards of the planet. We advise that you do not touch anything not mandated by the mission objectives, as your employee insurance does not cover burns.
Radioactive Exclusion Zone
Ravaged by thousands of years of high-intensity gamma radiation, this region of the planet is now a veritable hellhole of radioactive ash and decrepit, mutated flora. Move with great care, and pay particular attention that you maintain full detox procedure upon return.
Salt Pits
The Salt Pits of Hoxxes was once the location of a huge underground lake. It dried up billions of years ago and left huge crystallized deposits of red salt. Red salt - though worthless - tastes really good on Glyphid omelettes.
Sandblasted Corridors
This region is dominated by windblasted and arid tunnels reaching dozens of miles below ground. The particular composition of the surrounding rock means practically no moisture, resulting in one of the driest regions of the planet. With water being so precious, the inhabiting wildlife is particularly aggressive, ravenous for whatever fluids reside within their prey.
Azure Weald
Dazzling, bioluminescent clusters of lichen light up the darkness, illuminating this fertile and overgrown Region in flickering neon colors. Don't let that lull you into a false sense of security however - the Azure Weald brings to mind the deep jungle, in all its splendor and horror - and much like its terrestrial counterparts, it is absolutely not out to make friends. Kill or be killed - that is the law in this place.
Hollow Bough
Hollow Bough is a biological oddity that has the Science Department scratching their heads - this entire region of the planet is dominated by colossal, organic conglomerations resembling the inside of hollow trees. However, these structures are under attack by an invasive species of voracious vine-like plants, as much a threat to us as the planet itself. We recommend traversing these environs with extreme caution.
Deep Core
Below it all.
