About this game
Eclipse Below is a co-op survival horror game for up to four players. You and your crew are the last surviving members of a long decayed underwater bunker. The world above has perished, its surface scorched beyond recognition as the sun bloated into a red giant. Now, the only refuge lies beneath the waves, where water serves as a final eclipse, shielding what little life remains from the sun’s blind destruction.
Resources are gone, and time is running out. Your only hope is to pilot a decaying submarine through the abyssal depths in search of other bunkers- ancient relics of the old world that still hold precious oxygen, fuel, and scrap. These bunkers are your lifeline, but they are far from abandoned.
The journey between bunkers spans vast pitch-black oceans. Here, communication and teamwork are essential. Your submarine- rusty, slow, and barely holding together- requires constant maintenance and cooperation to stay alive. Whether you operate the bridge, man the navigation systems, or control the engines- every second counts; every decision matters.
The sea is cold and quiet… until it isn’t.
In Eclipse Below, everything is against you: the crushing pressure of the deep, the monsters that lurk unseen, the decay of the machines you rely on, and the relentless ticking of dwindling oxygen. You are not a hero- you are the lucky... for now.
The only question left is:
How long will you survive in the Eclipse Below?

Patch 6
Hello, After some good playtesting, a decent amount of bugs/ balance issues were found, so over the past couple days I've been focused on fixing those. Here's a list of those changes. -Fixed Undocking -Fixed Saving Audio Settings -Added the ability to toggle headbobbing -Added ability to set max FPS -Fixed Harbinger blocking exit -Fixed Data Logs Spawning wrong -Added the log for the spider -Fixed the lip on the port tube -Changed analysis part of the shadow eel log for better clarity -Tweaked sulker attack rate -(I think?) Fixed an issue with dying to the dog causing players to not be able to revive. I'm not 100% sure, but from my testing it seems to work.. Honestly I don't even know if it was actually the dog causing the issue or something else entirely. More testing is needed. -Added a small glowing part to the engine power that hopefully draws people's attention better. I've noticed this has been an issue with almost every group I've watched. -Fixed an issue with the camera getting unlocked while using a terminal -Moved some of the biome labels on the map to hopefully make the boundaries clearer- I may end up retexturing the map to color code the areas if it continues to be an issue. -Tweaked maximum stamina (increased) -Disabled rejoining active sessions As always, If you come across any bugs while playing please please report them- either with the feedback option in game or on the Discord. Have a good one, -CactusBallRead full article on Community Announcements (CactusBall)Patch NotesOfficial

Patch 3, I'm Back!
Hey ya'll, The transition to college has been a lot more involved than I had anticipated- now though, I have adjusted pretty well, and I have some time to begin working on the game again. I'm truly sorry for the delay in my roadmap and the radio silence over the past month, but know I have not forgotten this project. Today I released a really small patch that addresses an issue with ultrawide monitors, and changed how enemies interact with the starting rooms in a dungeon. Over the next couple days/weeks (I'm not sure how much time I will have) I will continue to work more on improving the enemy AI. I really really appreciate the support even in my absence! I will be posting updates on the Discord as I get things done. See ya! -CactusBallRead full article on Community Announcements (CactusBall)
