We Hear You – Bug Fix Update and Ongoing Optimisation Work

Warhammer 40,000: Mechanicus II · published 4 Jun 2026, 09:24 UTC

All eventsPlayers around this dateRead on Steam

First, thank you to everyone who has reported issues and shared feedback since the launch of Warhammer 40,000: Mechanicus II.

We know we’ve been quiet since launch. That hasn’t been because we’re ignoring the issues being raised – it’s because the team has been focused on investigating, fixing and preparing updates as quickly as possible.

We’re painfully aware that many players are experiencing performance issues, including lower than expected frame rates and unusually high GPU utilisation. Improving performance is a critical priority for us, and work is continuing on a more substantial optimisation update.

Today’s update addresses a number of commonly reported bugs and includes a small FPS improvement for many players. However, we want to be clear that this update is not intended to resolve the main performance concerns raised by players. That work is ongoing and will require a further update.

We understand how frustrating these issues are, and we appreciate your patience while we work to address them. We’ll share more details on the optimisation update as soon as we’re able.


Update 1.0.0.25 Patch Notes

General

Implemented a change that results in a slight FPS improvement for many players.

Fixed an issue where the Shadow Quality setting could reset to High after relaunching the game.

Fixed a missing placeholder icon for some skills.

Fixed an issue preventing certain territory expansion missions in the Adeptus Mechanicus campaign from loading.

Audio

Fixed a number of SFX being incorrectly tied to VO volume.

Fixed some missing VO dialogue.

Fixed some instances of dialogue being wrongly assigned to different characters..

Gameplay

Fixed an issue where Videx’s Motive Force skill could grant an incorrect number of Energized stacks.

Fixed an issue in the Vindication skirmish where reaching the extraction area before killing all enemies could incorrectly result in a defeat.

Fixed an issue where triggering a Kastelan Robot’s Deadly Demise trait could skip allied unit turns and disrupt turn order.

Fixed an issue where recruiting a high number of units for a mission (19+) could prevent units from being deployed into a skirmish.

Fixed an issue where the Necron Deathmark Skill Improvement upgrade increased the cooldown of Hyper-dimensional Jump instead of reducing it.

Fixed an issue where the Expanded Sicarian Armour tooltip could obscure the upgrade button and prevent the upgrade from being selected.

Fixed an issue where Nanoscarab Cloud did not gain an additional use at Dominion 8.

Fixed an issue where The Hungry Void command protocol did not apply to the Voidblade.

Fixed an issue where multiple units could be deployed onto the same cell during the deployment phase.

Fixed an issue where Pteraxii Sterylizors had access to Purgation Protocol before unlocking it.

Fixed an issue where A Call for Flesh could sometimes fail to spawn a Flayed One.

Fixed an issue where Khepra’s Emergency Protocol skill could not be activated after being unlocked.

Achievements

Fixed an issue where the Tech-Acquisitor achievement could fail to unlock after reaching 10 Cognition Points with Scaevola.

Fixed an issue on Xbox where the achievement notification pop-up did not display correctly.
