Housemarque has deployed Saros patch 01.004.003 on May 19, 2026, targeting severe progression-blocking bugs and broken weapon traits. This marks the fourth update for the sci-fi roguelike since its April 30 launch, prioritizing run-ending softlocks in the Cathedral and Ancient Depths over new content. Players should download the update immediately to prevent inventory and traversal glitches.
Immediate Impact: What Patch 01.004.003 Actually Fixes
Unlike the substantial May 5 optimization drop that introduced new color categories and Depth of Field tweaks, this patch operates as a strict maintenance pass. Housemarque’s focus narrows entirely on mechanical failure states that halt player momentum.
(If you were hoping for new meta upgrades or balance overhauls, you will have to wait. This update is purely about stabilizing the core loop.)
The most critical element of the 01.004.003 release is the targeted removal of softlocks. When a roguelike traps players in a specific room, the entire run collapses. Housemarque has eliminated two significant triggers:
- Cathedral Softlock Resolved: Players were clipping outside the boundaries of the Solar Cage within the Atrium of the Cathedral, leaving them stranded without a way to trigger the next encounter or extract.
- Ancient Depths Vault Gate: A scripting error previously prevented the Vault gate from opening upon clearing the designated enemies in the Ancient Depths, permanently halting forward momentum.
Beyond environmental breakage, the patch corrects two critical combat failures. The Gun Control trait—a vital modifier for managing crowd control—was simply failing to register when equipped on the Onslaught rifle. Similarly, the Incapacitor weapon was shutting down mid-run, leaving players without a functional loadout during high-stakes encounters.
Why is Housemarque releasing so many patches right now?
Saros launched on April 30, 2026. Releasing four patches in under three weeks is aggressive, but context is everything. Housemarque’s entire design philosophy relies on tight, repetitive combat loops. If players lose a multi-hour run not because of a skill check, but because a door refuses to open or a gun stops firing, trust evaporates instantly. These rapid-fire updates indicate the studio is prioritizing systemic stability over pushing new features, a necessary trade-off for a live-service roguelike's long-term health.

The Road Ahead: Stability vs. Content
With the most glaring progression bugs addressed, the immediate question is what Housemarque tackles next. The May 5 update set a baseline for accessibility and visual customization. The May 19 patch solidifies the mechanical floor. Players should watch the communication channels closely over the next two weeks. If the studio transitions from bug fixes to balance adjustments, expect the game's dominant strategies to shift.
For now, the directive is straightforward: install the patch before starting a new sequence of runs.
