Biomes are broad regions of Europa that define level generation. Each of these Biomes have unique characteristic creature spawns, terrain, and environmental obstacles.

Europa is an Ice Moon, and its entire exterior surface is covered in a thick sheet of ice, as hard as stone and bereft of life. However, beneath that surface ice, the environment resembles an inverse oceanic trench, with the icy less-hospitable water being closest to the surface, and the warmer, more life-sustaining water being found the further down a submarine goes. This is reflected in the arrangement of biomes, with heavily inhabited but sparsely biodiverse Cold Caverns being relatively safe, and the Hydrothermal Wastes at the bottom of the crater absolutely teaming with schools of myriad aggressive fauna, but being completely devoid of human habitation.

Biomes

There are 5 explorable biomes, each one progressively deeper than the last. Caves, Alien Ruins, Artifacts, and Wrecks are features common to all biomes, and each biome will come with their own varying explorative hazards in addition to these features.

Cold Caverns

The first biome in the campaign is the Cold Caverns. This region of Europa is made up almost entirely of the marbled ice that is the moon's crust.

The environment is composed entirely of hardened ice, periodically lanced with towering but destructible Ice Spires that are capable of puncturing subs. They are highly detectible on active sonar when compared to the level walls, showing up as orange-green streaks.
