The Abyss has changed. The Chaos Overhaul is the biggest Oathbreak Dungeons update since launch — and it touches nearly every part of the game. Online multiplayer has been rebuilt, Weapon Fusions have gained new Forms, bosses and minibosses have received major overhauls, the rune system has more than doubled in size, the soundtrack has gained an identity of its own, and the entire core of the game has been prepared for high-resolution and high-refresh-rate displays. There is also a new final boss waiting at the bottom of the Abyss. And he remembers you.
NEW FINAL BOSS — Lich of Memories
A unique arena, attacks, soundtrack, and reward.
3 NEW MINIBOSSES
Swamp Hydra, Glacial Guardian, and Ancient Iron Golem.
REBUILT STEAM P2P MULTIPLAYER
Major improvements to room, player, item, attack, buff, and progression synchronization.
REWORKED WEAPON FUSION

113 NAMED RUNE COMBINATIONS

A NEW MUSICAL IDENTITY

DRAGON AND JOKER REDESIGNED
New attacks, behaviors, and exclusive Relics.
120Hz, 144Hz AND BEYOND

MAJOR PERFORMANCE IMPROVEMENTS
Projectiles, particles, lighting, post-processing, and multiplayer.
A third final boss joins the rotation alongside the Dragon and the Joker. While the Dragon dominates through brute force and the Joker turns Chaos into a weapon, the Lich fights in a much stranger way: he turns memory into an attack. During a run, translucent echoes of defeated creatures may briefly appear throughout the environment, accompanied by the message:
“Someone... is still watching.”
During the battle, the Lich uses Soul Bolts capable of passing through platforms, teleportation, summons, and storms of memory.
The Lich records his own movement. Periodically, a spectral copy retraces part of the path he previously traveled — and can attack from positions where the real Lich stood seconds earlier. During the second phase, his memories begin to overlap, culminating in the Memory Storm and considerably more aggressive patterns. The Lich also has his own arena: a ruined crypt filled with books, shattered shelves, and fragments of a story that may have been better left forgotten. And, of course... his own Steam achievement.
All three final bosses now have exclusive rewards.
While above 50% health, your attacks deal +20% damage.
Every 7th attack deals double direct damage.
After avoiding damage for a while, you begin to recover health. Unlocking a boss Relic for the first time now triggers its own cinematic reveal, making these rewards immediately recognizable as something different from ordinary cards.
Three heads. Three behaviors. Each Hydra head serves a different purpose, and the fight evolves as they begin combining their attacks. During the second phase, the intervals become shorter, multiple heads attack in sequence, and the arena fills with:
Poison
Projectiles
Waves of bile
Precise parries can temporarily disable one of the heads, creating an opening to attack.
An extremely mobile fighter built around reading and reacting. The Guardian uses ice spears, crystal rain, and frozen zones, along with two unique mechanics:
She crystallizes her own body and rapidly crosses the arena before continuing her attack sequence.
The Guardian surrounds herself with ice armor that reduces incoming damage. The protection can be broken through brute force — or destroyed instantly by parrying the correct crystal. During the second phase, her patterns become faster and denser.
The Golem was designed around weight, impact, and openings. Its arsenal includes:
Overhead Slam
Wall Charge
Ground Pulse
Core Beam
Certain interactions expose the Golem's core, creating a temporary window of increased damage. Its model has also received full articulation: arms, legs, torso, and head now follow its movement and attacks. Displacement effects such as Black Hole also no longer make the Golem float around the arena.
Two existing minibosses have also received major visual overhauls. Corrupted Blacksmith Now uses articulated legs, arms, and hammer, along with unique poses for his attacks. Rift Priestess Now features an animated robe, articulated arms, responsive staff, dynamic halo, and runes that follow her casts. Their combat behavior has been preserved. The changes are focused on readability, animation, and personality.
Fusing weapons no longer means simply combining numbers. A fusion can now take one of 8 FORMS, dramatically changing how the resulting weapon behaves.
Fusing a weapon with another copy of itself creates a superior version with increased damage, speed, and piercing.
Two firearms are wielded simultaneously, alternating shots.
Each attack fires a rapid sequence of shots.
A firearm uses the melee weapon from the fusion as piercing ammunition. Yes. A shotgun can fire spears.
Preserves the melee weapon's attack while firing alongside the strike.
Two different firearms fire both projectile types simultaneously.
Two melee weapons become one enormous, slow, devastating weapon.
The same strike hits both in front of and behind the player. Each Form has also received its own visual feedback, making it immediately clear when a weapon has truly transformed into something new.
The Grimoire has received a new interface, including dedicated tabs for the Forge and Shop. The three equipped runes can now be rearranged through drag-and-drop, with dedicated controls for keyboard and gamepad. But the biggest change lies behind the interface:
Every trio of runes from the same element now has its own combination. And if you manage to assemble something without a specific recipe, the system still generates a procedural effect based on the runes used. No combination is left without a result.
Five new cards expand builds focused on active defense:
Parrying a projectile splits it into three homing shards.
A melee parry releases a wave that pushes enemies away and clears nearby projectiles.
Increases the knockback of all weapons. Enemies thrown into walls are stunned.
Projectiles explode when hitting enemies and deal area damage.
Parry now protects the entire body and remains active for longer.
The card visual system has received an extensive overhaul. The game currently features 59 buffs, and every card now has its own visual identity through unique illustrations or exclusive procedural sigils. Miniboss and final boss Relics have also received unique frames and presentations. The idea is simple: before you even read the text, you should feel like you've just found something special.
The Chaos rune has also been rebuilt. Instead of providing one fixed effect throughout the entire run, it can now change its behavior as you descend through the Abyss. In addition, the amount of Chaos accumulated directly affects which threat awaits you at the end.
The Dragon has gained new attacks and greater control over the arena:
Telegraphed meteor storm
Knockback wind blast
Fire breath
Charge
Claw strike
The Joker now reacts directly to the Chaos accumulated during the run. The higher your Chaos, the more unpredictable he becomes. At high levels, he can:
Attack more frequently
Stop time
Summon more clones
Unleash much denser projectile patterns
The soundtrack has undergone a major shift in direction. Instead of relying on short tracks selected at random, progression now uses stable themes tied to characters, places, and moments throughout a run. Three musical ideas run throughout the new OST:
OATH — determination, the player, and the oath.
ABYSS — corruption, the dungeon, and danger.
BROTHERS — memory, humanity, and what the Abyss failed to erase.
The descent itself now evolves musically:
The beginning of the journey and its central identity.
The dungeon begins to dominate the music.
The two motifs begin to collide before the final confrontation. Minibosses also have their own music. The Octopus' former contemplative theme has been replaced by a much more aggressive and syncopated track. The Hydra, Glacial Guardian, and Golem have also received dedicated themes. The Dragon, Joker, and Lich each have unique music. Defeating a miniboss now also ends its music properly instead of letting the battle theme continue playing in an empty room.
Defeating the final boss now has a conclusion worthy of the fight. The final blow begins its own sequence:
The boss receives a unique death animation
The arena's corruption begins to disappear
Persistent rewards are registered automatically
The music enters its final coda
Players receive a summary of the run
Only then do the credits begin
You no longer need to rush after rewards while the game is already trying to end the adventure.
Steam P2P received one of the largest overhauls in this update. Fixes include:
Connection failures caused by lost packets
Matches failing to start
Incorrect player names and levels in the lobby
Different rooms being generated for different players
Collected items remaining visible for other players
Remote attacks not displaying correctly
Incorrect or empty buff cards for clients
Problems when kicking players or closing lobbies
Failures during reconnection and late joining
Synchronization of fused weapons, items, and run states
We are also continuing to improve the behavior of complex encounters during online matches.
Vampiric Shot now restores 1 HP every 8 projectile hits.
Vampirist restores health every 6 hits.
Elite enemies now begin appearing only from Room 3 onward.
Maximum Elite chance increased from 18% to 20%.
Players who have already completed a run receive an additional +4% Elite chance.
Buff prices in the shop have been increased and now account for progression and card power.
Hydra and Glacial Guardian have received more health and more aggressive final phases.

High-resolution support and adjustable render density.
Proper support for 120Hz, 144Hz, and higher refresh rates.

Fixed the unlocking of Throne Hall upon reaching Room 50.
Implemented a retrospective verification system, allowing valid previous progress to be correctly recognized.
Improved achievement validation so that a temporary failure does not permanently prevent an unlock.
v0.0.1 was the beginning. The Chaos Overhaul is the update where Oathbreak Dungeons begins to take the form we always imagined for it: more unpredictable runs, absurd builds, bosses that demand attention, secrets, co-op, and moments you actually remember after the screen goes dark. We will continue monitoring balance, multiplayer, and extreme build combinations. But for now...
The Abyss has learned a few new tricks. 🖤
