About This 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…

  • Visceral, fast-paced FPS action, with top-notch weapon feel and combat responsiveness

  • Up to 4-players co-op

  • Roguelite meta progression with advancements, rewards, and unlocks

  • 64 hand-crafted levels, procedurally sequenced to make every run a new experience

  • 8 different weapons customizable with 45 weapon mods

  • Extensive pre-run and in-run character customization options

  • 36 different enemies and four bosses that will put your skills to the challenge

  • … and more content to come after launch!
