About the Game
Hidden Deep is a 2D action & exploration sci-fi thriller set in a mining and research facility – more than a mile under the ocean floor.
A group of researchers detected strange anomalies of unknown nature and organized an expedition to examine the mysterious phenomenon. Suddenly, after 681 days, contact with the researchers breaks off. You are the leader of the second team: Go down there, find out what happened, rescue anybody who is alive.
COMMAND YOUR TEAM – OPERATE EQUIPMENT – FACE UNKNOWN HORRORS
Control your team members directly or by giving orders. Accomplish your mission by coordinating different tasks. Explore the sub oceanic caves by using specialized equipment: grappling hooks, scanners, drones and heavy machinery are all part of your arsenal.
Defend against horrific alien life forms and other, undiscovered horrors that lurk in the deep.

Official update history
Hello!
This update restores split-screen mode, which stopped working after the addition of online mode. Currently, split-screen works with old split-screen maps, but all multiplayer maps will soon be supported.
Cheers,
Wookie
Hello!
This tiny hotfix fixes the "Could not get texture description" crash bug that was appearing on some PCs.
By the way, I would like to announce that an update with new content (levels and monsters) will be available next week.
Cheers,
Wookie
Hello everyone!
Here goes another small pack of fixes:
Single player:
Fixed crash-bug when character steps on slippery surface
Server racks did not react to player actions
Multiplayer:
Fixed a major desync when a character accidentally falls off an elevator or platform
Spiders was buggy on footbridges
Note regarding split-screen co-op:
Due to deeper code problems I temporarily disabled split-screen. It will be back by January 10, 2026. I apologize for the inconvenience!
Cheers,
Wookie
Greetings!
After a few enjoyable and very productive in terms of catching bugs multiplayer sessions with my wonderful Discord community, here comes another batch of fixes. I’ve fixed about 10 crash bugs, all related to multiplayer.
More fixes are on the way, along with more play sessions. Feel free to hop onto the Discord!
Cheers,
Wookie
Greetings!
Here's another batch of fixes:
Three random crash bugs like while switching weapon and other unpredictable moments
Broken character sync after leaving the crane in multiplayer
Bullet impact FX did not fire when monster got finishing shot
Problems when switching between Scan-Ball and character both in single and multiplayer
Also:
Added camera zoom adjustment in graphics settings in case your character renders too small. Also suitable for video capture
Tweaked Big-Fly monster so it can be killed with two 9mm shots instead of three if you hit in the center (belly).
I'm still investigating critical desync problem some of you are experiencing in co-op.
Cheers,
Wookie
PS. Multiplayer news soon.
I have a long-awaited fix for you: UI scaling to high resolutions. All main UI elements have been redrawn to achieve a high level of detail.
Additionally, the patch includes:
- performance optimization for DirectX 11
- fixed problem with key assignment, especially on AZERTY keyboards where there was a problem with the Z key
- fixed loss of stability when playing on a gamepad
- some minor fixes
ALSO I have one more little bonus this time only on the EXPERIMENTAL branch:
- In Survivors mode, I added an anti-fall jet engine. When you start falling, you can press the space bar and the engine will turn on and run for a maximum of 7 seconds. The next use of the engine will be possible after 1 minute (the icon in the window at the bottom will light up)
- This gadget has not been sufficiently tested yet, so it is in experimental branch
- You can select branch in Game properties->Beta (in Steam)
- Black screen when going into game menu in fullscreen mode
- Crash on Steam Deck
- Crash on game start (rare but was reported too)
I hope this time all will work fine. The only feature taken back is you cannot choose GPU Adapter in SafeMode launcher. If you need to change the adapter use the routine described in troubleshooting post.
Fixed: on some machines game was crashing after level fail screen
Apologies for the inconvenience.
Greetings explorers!
Here goes another hotfixes pack v0.95.41.5:
- fixed: on some PC game crashed on loading screen
- fixed: fps drops dramatically the longer you play in Depth Survivors
- fixed: crash when scan-ball explodes near big number of enemies
- fixed: game crashes when you shot the Scan-Ball and then press shift+1
- fixed: enemies electrocuted by Scan-Ball did not emit crystals in Depth Survivors mode
While we are hard at work with the most requested features, this smaller update contains the following content and fixes:
- Two new levels, selectable via ‘Load Mission’ submenu from ‘Play game’ if you already finished level Day 86.
- Day 89 - Security breach
- Day 92 - Disclosured
- Day 89 - Security breach
- Gamepad input further improved.
- Added keys to improve terminal and inventory navigation.
- Throwable rope now works like the other tools by using it with LMB/RT after selection.
- Fixed a crucial bug that crashes the game on loading if there was a zip-line mounted somewhere in the level.
- Some smaller tweaks and fixes.
- Fixed Direct X 11 rendering bugs.
Stay peeled for further updates in the near-ish future, until then: Happy exploring!
