Abyssus Update 1.3: New Features, Fixes & Cross-Platform Multiplayer

The Abyssus update has officially arrived — and it’s not just a small patch. With the release of Abyssus update 1.3, players are diving into a richer, more connected experience than ever before. From full cross-platform multiplayer to revamped skill trees and new sea shanties, this update delivers on everything fans have been asking for since the game’s launch. Whether you're a seasoned Brinehunter or new to the abyssal ruins, this is your definitive guide to what’s changed.

This update marks a turning point in Abyssus' evolution. It’s no longer just a solo roguelite shooter — it’s now a shared adventure across PC, PlayStation 5, and Xbox Series X|S. The developers at DoubleMoose listened closely to player feedback, and the results are clear: deeper customization, smoother gameplay, and more ways to team up with friends. If you’ve been waiting for a reason to dive back in, the Abyssus update is it.

New Features in Abyssus Update 1.3

The most anticipated change in the Abyssus update is undoubtedly the rollout of full cross-platform multiplayer. This means players on PC, PS5, and Xbox can now join forces seamlessly — no matter which platform they’re on. Gone are the days of being locked into isolated lobbies. Now, with just a few clicks, you can summon allies from across the digital ocean.

One of the standout additions is the Lobby Codes feature, allowing players to generate and share unique room codes via the Session Browser. This makes finding and joining games with friends easier than ever. You can now invite a PS5 friend to a PC session, or vice versa, using the “Join with Room Code” button — a massive leap forward in accessibility and community engagement.

Another highlight is the inclusion of two brand-new sea shanties. These aren’t just background music; they’re part of the lore and atmosphere. Players report that singing along during combat adds an unexpected layer of immersion — a nod to the game’s love for nautical themes. Community reports suggest these tunes are already going viral on Discord and TikTok, with fan-made dance challenges emerging.

Here’s a quick overview of the major new features:

The updated Soul Wheel is also worth noting. Previously, top-tier abilities were mutually exclusive, limiting build diversity. Now, all slots can be filled — provided you have enough Soul Fragments. This change opens up entirely new strategies, especially for players who want to experiment with hybrid builds.

Balance Changes & Bug Fixes in Abyssus Update 1.3

While new features steal the spotlight, the Abyssus update also includes critical balance adjustments and long-overdue bug fixes. One of the most requested changes was the ability to unlock the entire talent tree again — and the developers delivered. While the original 1.3 update introduced a tiered system to encourage specialization, community feedback made it clear that many players wanted full access.

As a result, the upcoming hotfix will allow players to unlock every node in the skill tree once more — though it will require more Soul Fragments to do so. This adjustment respects both the original design intent and player preferences, striking a balance between challenge and freedom.

Bug fixes are equally significant. The update resolves multiple issues that plagued early adopters, including:

• Fixed incorrect targeting in single-target attacks (previously affecting all players)
• Resolved Raging Storm scaling issues with windburst radius
• Fixed enemy line-of-sight logic errors
• Patched chest clipping into walls in the Submarine level
• Eliminated crashes caused by excessive lightning instances
• Fixed PS5-specific spawn crashes during boss encounters

These fixes improve stability and fairness, especially in high-stakes multiplayer runs. According to player experience reports, the number of mid-run disconnects has dropped by over 40% post-update.

Here’s a detailed breakdown of key fixes:

Additionally, the Backup Battery issue — a stack overflow crash that could occur during extended runs — has been patched. This fix is particularly important for players attempting high-depth runs or completing challenges like “Battery” (now reduced to 100 hits).

How to Prepare for the Abyssus Update 1.3

Before jumping into the new content, make sure your game is fully updated. The Abyssus update requires a full restart to apply the latest hotfixes. Players who skip this step may find themselves unable to join sessions with others who have downloaded the update.

Here’s a simple checklist to ensure a smooth transition:

1. Close the game completely — don’t just minimize it.
2. Restart Steam (or your console launcher).
3. Verify game files (Steam > Properties > Local Files > Verify Integrity).
4. Launch the game again — the update should now load automatically.
5. Check your lobby settings — enable “Join with Room Code” if desired.

For those eager to try out the new Soul Wheel mechanics, consider saving up Soul Fragments before diving into a run. Since the full tree is now unlockable, investing in higher-tier nodes will require more resources — but the payoff in flexibility is worth it.

You can also start testing new builds using the Brinerot pack, a cosmetic set released alongside the update. It includes a new helmet, armor, emote, and frame — perfect for showing off your unique style while hunting down Brine monsters.

Player Tips & Community Insights

Based on community reports and Discord discussions, here are some pro tips for thriving in the new Abyssus update:

• Use Lobby Codes strategically: Share codes with friends who prefer different difficulty levels or builds. This allows mixed-group play without forcing everyone into the same meta.
• Experiment with hybrid builds: With all Soul Wheel slots now fillable, try combining Fire and Ocean aspects for explosive synergy.
• Avoid the first wave of server congestion: The update launched on June 25, and many players joined simultaneously. Wait a few hours to reduce matchmaking lag.
• Report bugs via official channels: The DoubleMoose team emphasizes player feedback. Use the Steam Community hub to submit detailed reports — they’re actively monitoring.

One popular theory among players is that the new Brine God and his 15 blessings could unlock new endgame content later this year. While unconfirmed, early builds suggest the God’s abilities scale significantly with depth — making him a strong choice for high-tier runs.
