Quasimorph Patch 1.0.4 Notes

Quasimorph Patch 1.0.4 shipped on Steam September 7, 2026, continuing the Q3 post-launch quality-of-life cycle that began with Patch 1.0.1 and Patch 1.0.2. Magnum Scriptum described this update as the improved pathfinding and ally interactions pass that closes Q3 2026, alongside achievement fixes, storyline corrections, perk balance updates, and another batch of general QoL improvements and bug fixes. This page is an unofficial wiki digest; Steam news remains authoritative for exact build strings, balance numbers, and any follow-up hotfixes that arrive after publication.

If you are mid-campaign on story arcs that overlap with RealWare, Tezctlan, or Xiomara, read the balance notes before your next deployment — several perk changes shift class viability and ally behavior on high-skull contracts.

Pathfinding improvements

The headline change in 1.0.4 is improved pathfinding for both player clones and NPC allies. Magnum Scriptum addressed navigation issues where clones would take suboptimal routes around obstacles, particularly on multi-floor Descend missions and in cluttered industrial environments like RealWare stations. This is especially noticeable on VIP Escort missions where ally pathing reliability directly affects extraction success.

The pathfinding improvements also affect how enemies navigate during patrols and Investigate states — read the Enemy AI Guide for how smarter pathing changes patrol sweep patterns and door approach timing.

Ally interaction improvements

Patch 1.0.4 delivers better ally interactions during escort and cooperation missions. The improvements cover:

• Ally pathing reliability — NPCs follow intended routes more consistently, especially on multi-floor Descend missions and in complex station layouts
• Ally combat behavior — allies make better tactical decisions during combat, including weapon selection and positioning
• Escort mission VIP behavior — VIPs in Escort missions follow more predictable paths and avoid hazardous areas more intelligently
• Ally equipment usage — NPCs use consumables, pacts, and equipment more appropriately during extended missions

These improvements pair well with Mission Types for Escort contracts and Combat Stances when coordinating clone-and-ally room clears.

Achievement and storyline fixes

Patch 1.0.4 addresses several achievement triggers that failed to fire correctly after previous patches:

• Achievement tracking no longer resets incorrectly during story mission transitions
• Multi-floor extraction achievements now register properly on Descend missions
• Class mastery achievements reflect correct perk progression after the 1.0.4 perk updates
• Ending-related achievements trigger correctly at branch points — read Nine Endings Guide alongside this if you are trophy hunting

Storyline fixes include corrected trigger conditions on specific story missions that were impacted by pathfinding changes in previous builds. Route planning via Walkthrough Hub remains valid, but verify progress after updating if you were mid-arc during the patch window.

Perk balance updates

Several class perks received balance adjustments in 1.0.4:

• Perk tooltips updated to reflect current behavior — cross-reference with Classes Hub if you theory-craft build order
• New perk synergy interactions discovered between Eclipse Blades cannibalism and specific pact consumption rules
• Operator trait stacking clarified for multi-clone deployments

The perk changes do not rewrite any class tier rankings dramatically — see Class Tier List for current community consensus. Patch 1.0.4 refines rather than restructures the meta.

QoL additions: background FPS limit toggle

A welcome quality-of-life addition in 1.0.4 is the background FPS limit toggle. When disabled, other FPS limit settings apply normally. This addresses a common complaint where players wanted uncapped performance when Alt-tabbed or minimized while the game was still running.

Display improvements

Dodge chance is now displayed to the tenth — this subtle but important change gives players more precise feedback on encumbrance effects, equipment bonuses, and status effects that modify dodge. Previously, dodge chance rounded to whole numbers; the new precision helps optimization-focused players make better equipment decisions without relying on external calculators.

Pair this with Armor and Resistances and Loadout Planner when evaluating gear trade-offs.

Bug fixes in 1.0.4

The patch includes the standard batch of bug fixes:

• Pathfinding edge cases on specific RealWare station layouts corrected
• Ally spawn positioning no longer places NPCs inside walls on certain Descend mission configurations
• Inventory sort behavior stabilized when Cryochamber is full
• Achievement notification sounds now fire correctly after patch installation
• UI scaling corrections for 4K displays
• Localization string refinements across French, German, Spanish, and Korean

Relationship to the post-launch roadmap

Patch 1.0.4 slots into the Q3 2026 timeline as the fourth post-launch patch ahead of the Q4 2026 Bestiary and quality-of-life updates on the Post-Launch Roadmap. This appears to be the final Q3 patch before the promised Bestiary work arrives.

Timeline context:

1. July 31, 2026 — Patch 1.0 full launch.
2. Early August — Hotfixes 1.0.561 / 1.0.562 for stability and softlocks.
3. August 7–8 — Patch 1.0.1 for trading, inventory, and HUD QoL.
4. August 14 — Patch 1.0.2 for sorting, Cryochamber, and AI improvements.
5. August 21 — Patch 1.0.3 with balance, controller, and mission tweaks.
6. September 7 — Patch 1.0.4 with pathfinding, ally interactions, and Q3 closing fixes.

The Q4 Bestiary target and 2027 DLC remain on the horizon as announced.

Save compatibility

Patch 1.0.4 does not introduce save incompatibilities with the existing 1.0 campaign:

• 1.0 campaign saves — continue normally with pathfinding improvements applying to future navigation.
• Early Access saves — still incompatible with the 1.0 branch.
• Unstable Beta saves — may load; verify progress after updating.

Treat 1.0.4 as a standard client update for active campaigns.
