Warhammer 40,000: Mechanicus II System Requirements: PC Specs, PS5, Xbox Series X|S & Steam Deck Performance Guide

Warhammer 40,000: Mechanicus II is the sequel to the 2018 turn-based tactics cult classic, from developer Bulwark Studios and publisher Kasedo Games. It launched on 21 May 2026 for PC via Steam and the Epic Games Store, as well as PS5 and Xbox Series X|S, priced at $39.99. This is not a simple iteration. The sequel adds a second playable faction with the Necrons, a full second campaign, a cover system that the original deliberately lacked, and a complete overhaul of the leader progression system. Performance-wise, this is a genuinely troubled release. The official specifications describe a modest mid-range target, but independent testing found GPU utilisation issues that caused frame rates to drop below 60 fps even on an RTX 5080 at 1080p minimum settings. The game is officially Unsupported on Steam Deck due to graphics performance, and its Steam review score sits at 54 percent positive from over 2,200 reviews.

What this means in practice: The minimum tier targets 1080p at 30 to 60 fps on low-to-medium settings, though the developer has not published a specific frame rate target. The Core i7-7700 is a 2017 processor and the GTX 1660 is a 2019 mid-range card, so this is hardware from roughly six to nine years ago. The 6 GB VRAM floor is the detail that matters most: a 4 GB card will not meet this specification. The 12 GB system RAM requirement is higher than most turn-based tactics games list, and it reflects the game’s dual campaign structure and the Necron faction’s additional asset set. The 25 GB install size is moderate.

Recommended (Windows)

Component	Requirement
OS	Windows 10 (64-bit only)
Processor	Intel 9th Gen: Intel Core i5-9600K or AMD Ryzen 5 3600
Memory (RAM)	16 GB
Graphics	NVIDIA GeForce RTX 2070 (8 GB) or AMD Radeon RX 6600 XT (8 GB)
VRAM	8 GB
DirectX	Not specified on the Steam page
Storage	25 GB available space
Additional Notes	Requires a 64-bit processor and operating system.

What this means in practice: The recommended tier targets 1080p or 1440p at 60 fps on high settings. The i5-9600K is a 2018 processor and the RTX 2070 is a 2018 upper-mid-range card. The jump from 12 GB to 16 GB of RAM and from 6 GB to 8 GB VRAM are the two meaningful thresholds between tiers. If you have a gaming PC from the last five to six years with an 8 GB GPU and 16 GB of RAM, you meet the recommended specification on paper.

PC Performance Reality: Read Before Buying

The official specifications describe a reasonable hardware target, but independent testing reveals a game that does not perform as its specifications suggest. OC3D’s performance analysis found that even an RTX 5080 could not maintain a consistent 60 fps at 1080p with minimum settings and DLSS set to Performance mode. The reviewer stated plainly: “Even at 1080p, with minimum settings and DLSS set to performance mode, we couldn’t maintain a consistently stable 60+ FPS. Something was clearly wrong.” GameSpark’s Japanese-language playtest identified abnormal GPU load as one of two critical issues, noting that a Radeon RX 7900 XTX ran at 100 percent utilisation regardless of resolution or quality settings. The second critical issue was skill functionality failure, where hero skills would not trigger correctly during combat. A player on the Steam Community forums reported frame rate swings “from 15-60” on a system with a Ryzen 7900 CPU and RX 7900 XTX. Another player on Fatshark forums stated: “I can play it but I sometimes drop to like 50 frames on an RTX 4090 while nothing is happening.” The developer has acknowledged these issues and released multiple optimisation patches, including one on 30 September 2026 that reportedly delivered 3.12x higher average frame rates at 4K maximum settings on an RTX 5080 compared to day-one performance.

PlayStation 5 and Xbox Series X|S

Component	Requirement
Firmware	Latest PS5 or Xbox system software
Storage	Not specified on console store listings; PC version requires 25 GB
Performance	Specific resolution and frame rate targets not published by Bulwark Studios. Console versions were released simultaneously with PC on 21 May 2026.
Additional Notes	Single-player only. No multiplayer or online functionality. Full controller support. Physical editions available in Europe.

What this means in practice: The PS5 and Xbox Series X|S versions launched simultaneously with the PC version on 21 May 2026. Bulwark Studios has not published specific resolution or frame rate targets for either console. The game is a single-player experience with no multiplayer or online functionality. IGN’s review noted that the console versions exist but did not provide detailed technical analysis. Given the PC version’s documented performance issues, the console versions may also be affected. If you own a PS5 or Xbox Series X|S, the game is available, but check post-launch technical impressions before committing.

Nintendo Switch 2: Not Available

Warhammer 40,000: Mechanicus II has no Nintendo Switch or Switch 2 version. The game launched on PC, PS5, and Xbox Series X|S only, and Bulwark Studios has not announced plans for any Nintendo platform. If you play primarily on Nintendo hardware, you cannot access this game.

Steam Deck

Component	Requirement
Compatibility	Unsupported (Valve’s official rating). Confirmed by SREC and Rob’s Game Shack.
Performance	Yahoo Tech’s review stated plainly: “Not worth bothering with on Steam Deck.” DeckTube’s analysis confirmed the game is not playable on the handheld. A community member on GamingOnLinux noted “it had some performance issues on Steam Deck” in the demo.
Additional Notes	The game does not run on Steam Deck due to graphics performance. There is no announced timeline for a fix.

What this means in practice: Warhammer 40,000: Mechanicus II is officially Unsupported on Steam Deck according to Valve’s testing, with graphics performance cited as the reason. Yahoo Tech’s review was blunt: “Not worth bothering with on Steam Deck.” DeckTube’s dedicated analysis confirmed the game is not playable on the handheld. If you own a Steam Deck, this is not a game you can play. There is no announced timeline for a fix.

macOS and Linux: Listed by Third-Party Trackers, Not Confirmed on Steam

Steambase’s platform data lists Windows, Mac, Linux, and Steam Deck as supported systems for Warhammer 40,000: Mechanicus II. However, the official Steam system requirements list Windows 10 only, and Bulwark Studios has not published separate macOS or Linux specifications. I am treating macOS and Linux as unconfirmed. The original Mechanicus did have Mac and Linux versions, but the sequel’s official store page does not confirm them.

Price, Editions, and Content

Warhammer 40,000: Mechanicus II is priced at $39.99 / £34.99 / €39.99 on most platforms. A Digital Artbook DLC is available, and an Omnissiah Edition bundle includes the base game and additional digital content. The game features two full campaigns (Adeptus Mechanicus and Necrons), five named leaders per faction with their own upgrade trees, a cover system introduced for the first time in the series, and dynamic turn-based combat with squad management. It supports English, French, Italian, German, Spanish, Japanese, Russian, Simplified Chinese, and Korean with full audio support for some languages.

A Note on the Launch Controversy

The game’s launch was marked by significant player backlash beyond technical performance. IXBT Games reported that some players complained about the number of female named characters, with one Steam forum thread asking “does every playable named character HAVE to be a woman?” The game was labelled “woke” by some players, though the outlet noted that “not all players understand this concern.” Separately, IGN Portugal reported that the game was delayed from 2025 to Spring 2026 after fans criticised the demo’s decision to have Tech-Priests speak in plain English instead of the iconic corrupted binary language that defined the first game’s atmosphere. On Steam, the game launched with 60 percent positive reviews, with players citing “poor optimisation, simplifications compared to the first part, and the soundtrack.” 3DNews quoted one player summarising the sentiment as “a bitter disappointment.”

Final Verdict: Can Your PC Run Warhammer 40,000: Mechanicus II?

Warhammer 40,000: Mechanicus II has a modest hardware floor on paper but a genuinely troubled performance reality. The minimum spec asks for a Core i7-7700, 12 GB of RAM, and a GTX 1660 with 6 GB of VRAM, which is hardware from 2017-2019. The 6 GB VRAM floor is the hard GPU threshold: a 4 GB card will not meet the specification. The 25 GB install size is moderate.

The recommended tier asks for an i5-9600K, 16 GB of RAM, and an RTX 2070 with 8 GB of VRAM, which is achievable on most mid-range gaming PCs from the last five to six years. However, meeting the recommended specification does not guarantee a smooth experience. Independent testing found that even an RTX 5080 could not maintain 60 fps at 1080p minimum settings with DLSS enabled, and that GPU utilisation remained at 100 percent regardless of settings. The developer has released multiple optimisation patches, including a 30 September 2026 update claiming a 3.12x frame rate improvement at 4K on an RTX 5080, but the launch state was poor enough that many players recommended waiting for fixes.

On console, the game is available on PS5 and Xbox Series X|S, but Bulwark Studios has not published performance targets, and the PC version’s issues may carry over. There is no Nintendo Switch 2 version. On Steam Deck, the game is officially Unsupported due to graphics performance, with no announced timeline for a fix. There is no confirmed macOS or Linux version on the official Steam page.

Beyond performance, the game’s launch was marked by player backlash over changes from the original, including the removal of the choose-your-own-adventure tomb exploration, the introduction of a cover system, and a redesign of the leader progression system that Yahoo Tech’s review described as “rudimentary” compared to the original’s multiclassing depth. The Steam review score sits at 54 percent positive from over 2,200 reviews. This is a sequel that divides its own fanbase as much as it struggles technically.

Specs and performance may be revised by Bulwark Studios in future patches, and the developer has already released multiple optimisation updates since the 21 May 2026 launch.
