New biomes and enemies have been revealed in the deepest caves of Hoxes IV. Shoot, mine, rock and stone your way through the following new biomes:

• Hollow Bough, Hoxes IV strangest biological oddity, this biome appears to be the inside of a massive hollow tree, infested with vines.
• Crystalline Caverns, one of the most beautiful sights on Hoxes IV, unfortunately the silicate crystals are basically worthless.
• Sandblasted Corridors, one of Hoxes IV driest regions, dominated by wind blasted tunnels that will send you flying if you aren't careful.
• Dense Biozone, A subterranean rainforest, full of writhing carnivorous plant life. Be careful miners.

But beware, these new biomes also bring new threats, including the following enemies:

• Dreadnaught Twins (Arbalest & Lacerator)
• Septic Spreader
• Huuli Hoarder
• Nayaka Thrawler
• Barage Infestor

And some new enemies never seen before:

• Pod Spawner
• Mist Sprayer
