About the Game
Gather your friends and dive into Abyssus' fast-paced multiplayer shooting action. Fight through gorgeous hand-crafted levels in a roguelite adventure that will put your tactical skills to the ultimate test. Wield powerful brine-powered weapons and refit them with ancient technologies to gain an edge over your foes. Obtain divine blessings to enhance your firepower with elemental and mystic effects.
In a world powered by brine, a rare and powerful substance only found in the deepest fathoms of the sea, your team of daring brinepunk explorers is recruited to claim a massive deposit located beneath the ruins of an ancient civilization. However, your mission becomes a frantic battle for survival when the sunken kingdom’s corrupted inhabitants rise against you.
Will you survive to see the surface again, or will the abyss claim your life?
In Abyssus, cooperation means survival. Team up with fellow Brinehunters and carefully choose synergic loadouts, skills, suits, and weapon mods. Work together and fight through a merciless roguelite gauntlet, where no run is the same as the last.
Wield highly customizable, brine-powered armaments and infuse them with the might of ancient Gods. Master 8 weapons and 45 weapon mods, upgrading your skills and suit as you face the underwater kingdom’s mutated guardians.
Run after run, you’ll access more and more upgrades and tactical choices, but firepower alone won’t save you from the denizens of the depths. Mastering Abyssus's visceral gunplay and fast-paced action will require tactical coordination, positioning skills, and cohesive teamwork.
The world of Abyssus is richly atmospheric and steeped in mystery. What untold secrets lie in the sunken kingdom? What gives brine its inexplicable powers? Can we weaponize an anglerfish? The answers lie deep down below…

Greetings Brinehunters!
Today, our expedition reaches a new milestone! Patch 1.2 is out, bringing a new weapon, a new skill, new boss patterns, new challenges and cosmetic rewards, and an avalanche of balance improvements, bug fixes, and QOL updates. Take a look at the official Feature Trailer for a taste of what's waiting for you under the depths.
Patch 1.2 is but a step on our triumphal march to conquer the Abyss: soon we will disclose more information about the upcoming patch 1.3, which will be the biggest one yet. But without further ado, let's take a look at the brinefrosted bounty you'll get in this patch - for free, as always:
NEW WEAPON - HARPOON GUN
The favorite weapon of the Northern Reaches' hunters, now powered by brine. Trading fire rate for uncanny precision, each harpoon shot through primary fire will increase your combo point gauge, allowing you to unleash a secondary shot that will grow in power according to the amount of combo points spent. The perfect weapon for the Brinehunters who want a gun that packs a punch at any range, without sacrificing crowd control capabilities.
[img src="{STEAM_CLAN_IMAGE}/41122578/4b42bbeef72debd068fdff2334dca0fa5d48b58c.gif"]
NEW SKILL - SMITING SPEAR
Imbued with the energies of the Surge, the Smiting Spear is a pointed stick that sticks to the point: it will attach to whatever it is thrown against, be it an enemy or the environment, and deal continuous damage around itself. Ideal for zone denial, disrupting large crowds of enemies, and giving To'raka some of his own medicine.
[img src="{STEAM_CLAN_IMAGE}/41122578/eaadb663b6b2eb48ecc73e4a5d0ea93514f83e99.png"]
NEW BOSS PATTERNS
Forget your muscle memory and challenge the new incarnations of the Golemancer, Kri'Su, and Un'glu - now empowered by the powers of the Surge! Test your skills against their all-new attacks and unexpected abilities. There is no comfort zone in the depths below...
[img src="{STEAM_CLAN_IMAGE}/41122578/f4aedfb7c059e778579cdc3a7a9f7d94c8bd2cb4.png"]
NEW COSMETICS AND CHALLENGES
New content means new challenges, and with new challenges come new rewards! Face the danger of the depths with the brand-new gear implemented in 1.2, and you’ll be able to unlock warm clothes and festive cheer for the frozen season. And if frozen is precisely what you’re looking for, you can support us by buying the new Brinefrost DLC! As usual, this is a cosmetic-only pack; made to support our work on the following content patches, which will bring even more free game content!
[dynamiclink href="https://store.steampowered.com/app/4168330/Abyssus__Brinefrost_Pack/"]

Greetings from the depths, Brinehunters! We’re excited to let you know that the quest for Brine continues, with more coming in early 2026. On January 12th you can get your salty hands on the new 1.2 patch, with all new content including:
A brand new weapon
A new skill
New challenges
New cosmetic rewards
A New Weapon - The Harpoon Gun!
For the Brinehunter who’s already unlocked everything (and for those still on your way) the Harpoon Gun provides another nautical edge to your brine-soaked adventure!
This pointed precision weapon bridges the gap between Brinehunters’ slower Combat Bow and the faster Brine Rifle - and enters the Abyss with eight upgrades available through the Ancient Forge!
Upgrades also help with more than just piercing power! Each Mod will stick harpoons to enemies (or the environment if you have enemy-piercing). To stop you having to keep track of enemies you’ve stuck with harpoons, we’ve also introduced the Combo System, just for our new Harpoon Gun.
Each harpoon has a way to increase your combo points - which will be used by the Harpoon Gun’s secondary fire to increase effects depending on how many points you have in the bank. More combo points, more explosive impact. Rack them up and then deal out the damage with a range of secondary fire options to choose from.
[img src="{STEAM_CLAN_IMAGE}/41122578/8b73da9b796238551f2a1ceeabcdf5575b903329.gif"]
A New Skill - The Smiting Spear!
Alongside the pointed new Harpoon Gun we have an additional spiky skill for you with the all-new Smiting Spear. This Surge-powered spear deals continuous damage through a devastating aura, sticking to enemies and the environment alike.
Take the Smiting Spear with you to provide area control and wide-ranging group damage down in the Briny depths. Throw the spear into the environment or an enemy to do continuous damage wherever it lies!
In addition, shooting the spear once it’s stuck in place causes additional damage pulses - linked and scaling with explosive damage buffs like Mr. Boom! If you REALLY want to make an area inhospitable, you can have up to six active spears, all dealing ongoing damage to their immediate surroundings.
While it’s always good fun and good strategy to stick the Smiting Spear into the scenery, impaling an enemy also comes highly recommended! Enemies stuck by the spear will carry it with them, and should they fall while impaled, the Smiting Spear will stand where they fell, to carry on dealing damage.
[img src="{STEAM_CLAN_IMAGE}/41122578/057003d636a1987f9303f4bcc0715589eae7a9b6.gif"]
New Challenges (And Cosmetic Rewards)
We’re also delivering new challenges for you in the Abyss - and in-game rewards for those who manage to defeat these during your time in the darkest depths. We don’t want to spoil the challenges or rewards too much, but you can find these yourselves in game.
New Boss Variations
After your first complete expedition, Brinehunters will find alternative variants of our old bosses available in the Abyss! Each boss variant comes with their own evolved moveset and elemental variations - as well as a new look - to keep Brinehunters on your toes!
[img src="{STEAM_CLAN_IMAGE}/41122578/2bf1cc95a58b15b2e91a1ca561a70f85c1d710e8.gif"]
Bug fixes, Balancing, and Quality of Life
A huge thank you to all of the Brinehunters who continue to dive into the Abyss and come to leave feedback in the Official Abyssus Discord! Your support is incredible (especially those of you who come back with Brine) and we’ve got a solid selection of bug fixes and tweaks in here.
Please continue to keep the feedback coming in our Discord, and we appreciate all of you!
A New Paid DLC Pack
As promised, and as always, we also have a cosmetic-only DLC where Brinehunters can provide additional support to the team! The Brinefrost Pack provides an ice-cold edge, with a new suit, helmet, frame and an interactable emote.
The Brinefrost DLC continues our pledge to deliver entirely optional-only DLC which won’t have a material impact on your journey in the depths of the Abyss!
[img src="{STEAM_CLAN_IMAGE}/41122578/73b02b899af1909827b53d89490056d819783407.png"]
So that’s our 1.2 update rounded up! We do note that there seems to be a LOT of Brine left in the Abyss, and you Brinehunters have still not managed to bring it all back! We hope that you have a great time with the new Harpoon Gun, Smiting Spear, challenges, boss variations and all the smaller tweaks in 1.2.

Ho there, Brinehunters!
We wanted to let you know that we’ve got a hotfix plunging down towards the Abyss as we speak - bringing some needed balancing and bug fixes to the Abyssus 1.1 release. We once again thank you for your incredible support, and for all of the feedback you’ve been sending in.
We’ve four main elements for this hotfix, to help you navigate your way through the Briney depths:
Fixed a crash related to Enemy navigation
Added an “I’m Stuck” button to help you get out of places a Brinehunter should never have gotten into (though this won’t be available during Boss fights)
Fixed a potential softlock where Brinehunters could encounter rooms which don’t recognise completion
Fixed a bug where players’ maximum speed was capped incorrectly (it is now capped at 300% and not the previous 2,500%)
We continue to monitor gameplay closely and will continue to fine tune the darkest depths based on your feedback. Please do head down to the briney depths and let us know how these balances feel, and send a telegram with your thoughts via Discord or our social media spaces.
The quest for Brine and Glory continues!
Drop your thoughts on our Discord or community channels.
