Abyssus Weapons Tier List

Community-tested rankings for every gun — updated for current Steam meta and Brine 10+ expeditions.

This tier list ranks all eight Abyssus weapons by overall expedition value on Steam — room clear speed, boss damage, Blessing synergy, Forge Mod support, and performance at elevated Brine levels. Abyssus is a roguelite FPS from DoubleMoose Games where weapon choice interacts tightly with Blessings, Charms, and abilities; a B-tier gun with perfect rolls can outrun an S-tier pick with bad altars. Use these tiers as a starting framework, not gospel.

Rankings reflect solo and co-op consensus from high-depth clears, developer deep-dive commentary, and post-patch balance notes. Weapons are compared at comparable unlock states — fully challenged fire modes, reasonable Forge Mod access, and at least one complementary Charm by mid-run.

S Tier — Meta Defining

S-tier weapons dominate most tier lists because they solve two problems at once: packed enemy rooms and priority target deletion. You will see at least one S-tier gun in the majority of Brine 12+ clear videos and leaderboard runs.

Weapon	Strengths	Best For
Tesla Gun	Spark orb crowd control, chain lightning, low aim demand	Add-heavy depths, co-op mob management
Plasma Launcher	Massive AoE explosions, screen-wide clear with Ms. Boom	Fast room routing, Blazing Weapon unlock farmers
Brine Revolver	Weak-spot multiplier, precision secondary modes, boss burst	Herald elites, Royal Abyss bosses, solo target DPS

A Tier — Excellent Specialist Picks

A-tier weapons either trade raw AoE for consistency or require specific build support to match S-tier output. They are default picks for experienced players running synergistic Blessing stacks.

Weapon	Strengths	Best For
Combat Bow	Sustained precision DPS, strong Turret pairing	Infinite Turret builds, objective burn, safe mid-range
Fish Deity	Unique projectile patterns, strong late-run scaling	Players who unlocked all three Royal Abyss elites

B Tier — Situational but Viable

B-tier weapons can clear full runs — especially at moderate Brine — but demand more effort or narrower positioning as difficulty scales. They shine in specific arenas or early progression before chase unlocks arrive.

Weapon	Strengths	Limitations
Engine Rifle	Balanced stats, starter accessibility, forgiving recoil	Outscaled by specialized guns at high Brine
Shotgun	Extreme close-range burst, strong depth 1–2 clears	Range and kiting enemies punish shotgunners late
Disc Thrower	High ceiling ricochet damage in skilled hands	Inconsistent without arena knowledge and mod support

C Tier — Not Currently Competitive

No weapon in Abyssus is hard C-tier trash — the roster is small and every gun has a niche speedrun or challenge category. If a formal C row feels empty in current meta, interpret it as "weapons that require disproportionate investment to match S-tier throughput." Today that usually means running the Shotgun or Disc Thrower without compensating Blessings on Brine 15+, or sticking with the Engine Rifle after unlocks are available. Swap to Tesla, Plasma, or Brine Revolver when your goal is consistent clears rather than challenge runs.

How We Rank Weapons

Tier placement weighs four factors equally: room clear speed (how fast you regain altar tempo), boss damage (Herald and Royal Abyss phases), build flexibility (how many Blessing and Charm combos work), and skill floor (how punishing bad aim or positioning feels). Tesla Gun spikes on skill floor and room clear. Brine Revolver spikes on boss damage. Combat Bow spikes on build flexibility with Turret setups. Disc Thrower scores high on ceiling but low on floor, anchoring it in B-tier despite highlight-reel potential.

Frequently Asked Questions

What is the best weapon in Abyssus right now?

For general-purpose high-Brine runs, the Tesla Gun and Plasma Launcher share top billing. Tesla excels at effortless mob control with spark orbs; Plasma deletes entire rooms with AoE explosions. For single-target boss damage, the Brine Revolver remains unmatched.

Why is the Shotgun ranked lower than other Abyssus weapons?

The Shotgun delivers excellent burst damage at point-blank range, but Abyssus elites and bosses increasingly rely on spacing, dashes, and arena hazards at higher Brine levels. Without reliable mid-range tools or crowd-control secondary modes, the Shotgun falls to B-tier despite strong early-depth performance.

Is the Combat Bow really A-tier without S-tier AoE?

Yes. The Combat Bow offers consistent precision DPS, strong Blessing scaling, and the best natural pairing with the Turret ability. Teams running Infinite Turret builds often elevate the bow above raw tier labels because sustained objective damage matters as much as room clear speed.

How hard is it to unlock S-tier weapons?

The Tesla Gun unlocks relatively early through standard weapon challenges. The Plasma Launcher requires completing The Blazing Weapon challenge — a deliberate mid-game milestone. None of the S-tier picks are pay-gated; they reward expedition knowledge and challenge completion on Steam.

Does tier rank change in solo versus co-op?

Solo runs scale enemy counts down, which slightly boosts weapons with limited crowd control like the Brine Revolver and Combat Bow. Co-op favors AoE kings — Tesla Gun and Plasma Launcher — because add waves multiply with player count. Adjust expectations by team size, not just raw tier letter.
