Explore compact underwater environments in The Hull, an intense co-op descent game where strategic combat and limited supplies define your survival.
About this game
This is not a run-and-gun shooter. Movement is deliberate, enemies hit hard, and staying too long makes the facility more dangerous. Each day sends your crew into abandoned underwater facilities where danger rises the longer you stay. You play as a Fathomwalker pushing deeper through nine increasingly hostile dives.
Movement is deliberate, resources are limited, and every decision carries weight. Most dives last between three and ten minutes depending on the day, and success depends on coordination, rationing, and knowing when to retreat.
Designed first and foremost for 1–4 player co-op, The Hull is fully playable solo but balanced around teamwork and shared resource management. It delivers a compact, atmospheric survival experience instead of a long campaign or deep buildcraft systems. 
Facilities are tight, unstable, and hostile. Traversal is slow and methodical, and enemies hit hard. Clearing a room does not guarantee safety because the threat level rises over time and pushes more danger into the facility. The challenge comes from surviving the increasing pressure rather than solving puzzles or exploring large spaces.
Ammo and healing are intentionally scarce. You cannot craft supplies during a dive, so every shot and every point of health matters. Teams that share resources, avoid unnecessary fights, and stay disciplined have the highest chance of making it back to the surface.
Between dives, you regroup aboard The Hull, a rusted vessel that serves as your lifeline. Here you craft weapons, upgrade your suit, and prepare for the next run. Progression is focused and easy to understand. It emphasizes consistency and power scaling rather than complex build trees or branching systems.
Choose from a curated set of SMGs, rifles, shotguns, and precision weapons. Each one fills a clear role and uses one of three ammo types.
Each dive becomes more dangerous the longer you stay. Deeper levels introduce more aggressive enemies and more unstable environments. The goal is to survive the run, extract what you can, and decide whether to push your luck or escape before the threat level becomes overwhelming.

March Development Update
Hello Fathomwalkers, Just sharing a quick development update with you as we enter March. Patch 1.06 is in testing right now. It is a smaller patch that focuses on cleaning up some enemy behavior, fixing a few lingering bugs, and making single player feel closer to the pace you get when playing with more people. Movement feels a bit better, co‑op visibility is less awkward, and a few items and enemies have been adjusted so they line up with what they were meant to do. If everything looks good, it should be out within a few days with the actual patch notes. After that, we are shifting to Patch 1.1, our first "major" game update. The main goal is to break up the repetition by adding boss fights. These will act as real moments in a run that change the pace instead of everything blending together. We are also adjusting how the game ramps up as you go deeper so the difficulty feels more varied from dive to dive. We hope to be able to ship this update within a few weeks but make no guarantees if we will be able to deliver on that so please stay tuned. A big thanks to everyone who has supported the game so far. Whether you bought it, left a review, or pointed out issues, even the negative stuff helps us improve the game and get it into the best shape it can be. Praise the Hull.Read full article on Community Announcements (Mire Studios)Patch NotesOfficial
