Mechanical Abyss
Layer 4
Light level Dark
Civilization Mechanical Dome
Boss The Ambassador


The Mechanical Waters appears as one of the fourth biomes in the current game. It is a dark, mysterious place where every surface is made from a strange biomechanical product, a black, oily substance flows, and only the frequent unnatural red lights illuminate this twisted, monochromatic environment, where flesh and technology interwoven form the unfeeling, monstrous creatures that dwell in such a watery grave. The boss of the Mechanical Waters is The Ambassador.


The Mechanical Waters is an alternate version of the Ancient Abyss, where some powerful technology began to consume and merge with the lush fauna and flora, slowly turning them into the monochromatic, dark and disturbing biomechanical creatures that roam in the oily, polluted waters flowing in the dark reaches of this corrupted biome.


The water in this biome is oily and sticky, and will hinder movement and vision in any flooded areas in the Submarine, often making it difficult to spot dents and holes, or even smaller enemies crawling inside the ship. Additionally, ingesting this oleagenous liquid can make you become Oil Drenched, severely hindering your vision, as well as further diminishing your character's efficiency in repairing and fighting by lowering their Stats.


A list of enemies that can be found in the Mechanical Waters biome:

This biome's civilization is the Mechanical Dome, a destroyed and corrupted ancient egyptian city that once sat inside of a now broken glass dome, now a large factory wherein the mechanical infection replicates and prospers, and that is populated by the disturbing Reborn Ones.


  • The Mechanical Waters is heavily inspired by the works of H.R. Giger.
