Listen up and sharpen your pickaxes, miners! A whole new region below the surface of Hoxxes IV has been discovered, with four new biomes to explore. They are full of valuable minerals, but also new environmental challenges, biological hazards and a bunch of new creatures. Preserve your ammo, and be prepared to fight the biggest creature you have ever seen; the terrifying Dreadnought, much bigger than even the ugly Oppressor. Hoxxes IV will not easily give up on its valuables, so get ready to hack, slash, shoot and stomb your way through icy caves, molten rocks, gooey caves and wonderous, luminescent, underworld jungles. —description from the publisher
