Abyssus Tips and Tricks Guide

Abyssus is a co-op and solo first-person shooter roguelike with a brinepunk theme and a heavy focus on weapon unlocks, elemental blessings, and meta progression. The game can feel very different depending on whether you play alone or with friends.

These tips cover everything from combat and progression to boss strategies and hidden objectives.

Focus on Meta Progression Early

Spend Soul Fragments between runs at the Soul Wheel in camp to unlock new weapons and abilities.
Prioritize upgrades that give extra ability charges, open more upgrade stations, and increase damage output.
Unlocking turrets instead of grenades can be a game-changer for sustained damage.

Know the Solo vs Co-op Difficulty Gap

Solo runs are significantly easier than co-op. Enemy health and numbers drop, making fights quicker and less punishing.
In co-op, expect more enemies, higher health pools, and mechanics that require precise coordination.
If you are stuck in co-op, use solo runs to unlock more upgrades and weapons before returning with friends.

Learn Boss Mechanics

Bosses use MMO-style mechanics like invulnerability phases, AoE attacks, and hazard zones.
Move constantly to avoid environmental damage and time your attacks for vulnerable windows.
Certain bosses, like the Sanctuary Elite or Royal Abyss challenges, are tied to weapon unlocks.

Use Elemental Blessings Wisely

Blessings can be applied to primary fire, secondary fire, and abilities.
Fire burns over time, Ice freezes, Lightning chains between enemies.
Tentacle blessings throw rocks, Shadow blessings debuff, and Spirit blessings unleash stored damage.
Combine blessings for maximum effect, such as pairing Ice control with Lightning AoE.

Unlock Weapons Through Challenges

Some weapons require specific actions beyond Soul Fragment purchases:

Plasma Launcher – Complete “The Blazing Weapon” by quickly reaching the Royal Abyss.
Fish Deity – Defeat all three Royal Abyss elites to trigger the pond event in the lobby.
Tesla Gun – Defeat the Gardens Elite.
Brine Revolver – Found in the lobby after progressing far enough.
Disc Thrower – Destroy hidden crystals after the second boss.

Manage Resources for Longer Runs

Save healing stims for late-stage bosses and elites.
Use the environment for cover to reduce damage taken.
Keep an eye out for healing stations in each region.
Maximize gold pickups to buy key upgrades during a run.

Explore for Hidden Objectives

The secret pond puzzle requires defeating all three Royal Abyss elites, each tied to a lobby fountain statue.
Destroy Surge Fissures in each major zone for achievements and rewards.
Complete challenge rooms for bonus loot, but be prepared for high-risk modifiers.

Balance Weapons and Abilities

Experiment with every weapon to find what works best for your playstyle.
Unlocking all mods for a weapon significantly boosts its performance.
Some achievements require mastering every weapon, so rotate loadouts regularly.

Final Blurb

Abyssus rewards players who experiment with blessings, master boss mechanics, and invest in meta progression early. Solo runs are perfect for unlocking upgrades, while co-op provides the most intense and coordinated battles.

With hidden objectives, weapon-specific challenges, and powerful blessings to combine, there’s always a way to push deeper into the depths.
