About this game
Unknown Depths
The newly discovered ocean planet Xyphos-6 hides extremely valuable artifacts and resources in its deep waters, for the brave or the foolish enough to venture there.
Deep Ocean Exploration
The depths are yours to explore, as long as your submarine doesn’t collapse under the pressure… or from something else.
Into the Void
Leave the safety of your submarine in a diving suit and venture outside. Beware: only careful preparation and planning will save you from certain death.

Sub Navigation Explanation
Hi everyone! I just wanted to show some progress on how the submarines will be controlled in the game. Please keep in mind these are work-in-progress images.Navigation ElementsHere are the main controls you will use to pilot the sub:Manometer: Indicates internal pressure. This represents the submarine's hull status. If the indicator rises into the caution area, it is time to go outside and check the hull for small fractures. If left unchecked, it will reach the danger area, drastically increasing the chance of flooding.Radar: Displays creatures and beacons. The player can adjust the detection interval to avoid attracting too many dangerous creatures.Scanner: Since there are no windows, this screen shows a point-cloud representation of the outside world.World Map: Shows the entire map and your current position.Terminal: Here, you can plot routes for automatic navigation. You can then sleep to "fast travel"; depending on the route, you might arrive safely at your destination, or wake up to an emergency!Communications: When close enough to a beacon, this will beep to indicate a recorded message is available to play.Ascent and Descent: The map is 3D, but navigation uses 2D depth layers. Changing from one layer to another is the equivalent of moving to a different biome or area.Speed Lever: Adjusts the speed or switches to reverse.The Yoke: Steers the submarine while moving forward or backward.Maneuver Lever: Allows for precision movement, but at a higher energy cost.Power Indicator: Shows remaining energy in the generator. Once depleted, it is time to insert a new uranium rod.There are many ways to make navigation realistic, but I want to keep it simple so players can focus on other aspects of the game.Diegetic UIThe goal is that, with few exceptions, all functions will be represented in-game without a HUD or on-screen menus. The position of the equipment and the camera are adjusted so the player can quickly see overall information at a glance.I believe this will add to...Read full article on Community Announcements (Inmersionbit Dev)AnnouncementsOfficial
A huge thank you + What I’m working on (Submarines!)
Hi everyone,I just wanted to drop a quick note to say how surprised and grateful I am for the initial reception of the game. Seeing everyone’s interest really motivates me to keep pushing forward!Right now, I’m deep in development working on the modular kit used to create the submarines.I don't plan to have full custom/player-built submarines in the initial release. However, because I'm building everything on this underlying modular system, adding that feature down the road is definitely feasible. I’m really excited to show you how this looks. Keep an eye out for the next post, I'll be sharing a first look at the system then.Thanks for your support!Read full article on Community Announcements (Inmersionbit Dev)
