About Abyssus
Abyssus is a fast-paced multiplayer shooter for up to four players. You and your fellow Brinehunters descend into the ruins of an ancient underwater civilization to claim a massive deposit of brine, a rare substance that powers the world. When the sunken kingdom’s corrupted inhabitants rise against your team, the expedition becomes a fight to survive.
The descent
Fight through hand-crafted levels in a roguelite adventure, with more than 70 levels procedurally sequenced so each run is different. The kingdom’s secrets and the source of brine’s powers lie deep below, guarded by 36 kinds of enemies and 12 bosses.
Build your team
Before and during a run, choose and customize your loadout, skills, suit and weapon modifications. Coordinate with your team on positioning and tactics: surviving the depths takes more than firepower. Roguelite meta progression adds advancements, rewards and unlocks, giving you more upgrades and tactical choices over successive runs.
Weapons and upgrades
Master nine brine-powered weapons and customize them with 45 weapon mods. More than 140 Ancient Forge mods further empower weapons and skills, while Charms and Blessings let you shape your build. There are over 250 Charms and Blessings, including divine blessings that add elemental and mystic effects to your firepower.
Co-op combat
Fight alongside up to three other players in fast-paced battles. You wield customizable brine-powered weapons infused with ancient technologies and the might of ancient Gods as you face the kingdom’s mutated guardians.
