How co-op works
Up to four online Brinehunters enter the same run with independently chosen weapons, suits, skills, mods, Charms, and Blessings. Players design complementary loadouts, hold different firing angles, focus priority enemies, and coordinate positioning and elemental effects through procedurally sequenced rooms and bosses.
About this game
Abyssus is a brinepunk roguelite FPS that supports up to four players working together online. You and your crew descend into the ruins of a corrupted undersea civilization, choosing loadouts and wielding godly powers to fight your way through procedurally shifting depths. Each run offers true cooperative action as you face down waves of hostile denizens.

Combat is fast and aggressive. You customize your arsenal before diving, then blast through enemies with tight gunplay while unleashing devastating abilities. The roguelite structure means every descent brings fresh challenges, loot, and tough choices. Playing with others amplifies the chaos and opens up tactical opportunities as you coordinate fire, share resources, and revive teammates under pressure.
Online co-op supports the full four-player squad experience. Runs demand communication and quick decision-making, especially when bosses arrive or the environment turns hostile. The brinepunk setting and run-based progression make Abyssus a strong pick for groups that enjoy high-octane cooperative shooters with replayability built in.

Frequently Asked Questions
Can I play Abyssus solo, or is it designed for co-op?
You can play solo or with up to four players online. While the game supports single-player, it's built as a cooperative experience where teamwork, communication, and coordination really shine during the chaotic firefights and boss encounters.
Does Abyssus have local/couch co-op?
No, Abyssus only supports online co-op. You'll need an internet connection to play with friends.
How does the roguelite structure work with multiplayer?
Each descent is a fresh run with procedurally generated levels and loot. You and your squad choose loadouts before diving, then make tactical decisions together as you progress through the corrupted ruins. When a run ends, you start a new descent with different challenges and gear opportunities.
Is teamwork required, or can everyone just shoot independently?
While you can certainly blast away on your own, Abyssus rewards communication and coordination. Sharing resources, reviving teammates under fire, and coordinating abilities during boss fights or environmental hazards makes runs significantly smoother and more successful.
