Why players say this

Steam review verdict

Fun gameplay with both factions playable, but repetitive missions, numerous bugs, a weaker soundtrack, and a general step down from the first game hold it back.

What players like

Gameplay is fun: The core gameplay loop is widely praised as entertaining and enjoyable, with many noting that the game is fun to play despite some repetition. The tactical combat and overall mechanics are considered engaging.

Both factions playable: The choice between playing as Necrons or Mechanicus is appreciated, offering variety and replayability. This feature is a key positive for players.

Common complaints

Soundtrack is worse than original: The music is less memorable, less epic, and not as impactful as the first game's soundtrack. Repeatedly cited as a major letdown.

Worse than the first game: The game is widely considered a downgrade from its predecessor, lacking improvements and charm. Many reviewers feel it loses the essence and quality of the original.

Generic and unmemorable experience: Compared to the first game, this sequel feels generic and loses its unique character. The atmosphere, voice acting, and story are also worse.

Numerous bugs and crashes: The game suffers from frequent bugs, glitches, and crashes, including game-breaking issues. This affects stability and overall enjoyment.

Customization reduced compared to first: Players report less customization and fewer options than the first game, making the experience feel more limited and less personalized.

Gameplay and performance

Two playable factions available: Players can choose between Adeptus Mechanicus and Necrons, each with their own campaigns and units. This dual-faction structure is a core feature highlighted by many reviewers.

Turn-based tactical combat: The game is a turn-based strategy title with tactical combat, similar to the first game. This is a fundamental gameplay characteristic noted across multiple reviews.

Two separate faction campaigns: The game offers distinct campaigns for the Mechanicus and Necron factions, each with unique mechanics and stories. This is a major selling point, providing significant replay value.

Tech-priest leader system: Players control tech-priests with distinct skills and playstyles, leading squads of units. The game features a progression system for these leaders, adding depth to the tactical gameplay.

Upgrade and progression systems: Both units and leaders can be upgraded and customized, with global progression systems. This customization is a key element that enhances player agency and long-term engagement.

Terrible performance and fps drops: Players consistently describe the game's performance as terrible, with stutters, FPS drops, and instability even on lower settings or high-end PCs. It is a core, commonly repeated complaint.

Frequent crashes and freezes: Many users report the game crashes, freezes, or locks up, including at startup, after actions, and within short play sessions (10-40 minutes). This is observed repeatedly and appears highly frequent.

General bugs and stability: Feedback points to general bugginess, stability problems, and optimization issues that lead to crashes and performance problems. The game feels unpolished in several areas.

Lack of optimization on PC: The game is reported as poorly optimized for PC, showing high GPU and CPU usage relative to its visual quality and not scaling well with lower-end hardware. Several users call out optimization as non-existent.

Stutters during specific situations: Users encounter stutters and frame drops in particular scenarios, such as on certain maps, with visual effects (volumetric fog), or when specific units (Triarch Praetorians) take action. This indicates situational optimization problems.

Recommendations

Not recommended overall: Many reviewers express a strong negative recommendation, citing bugs, performance issues, and dissatisfaction with the sequel. This sentiment is widespread and specific.

Recommended for franchise fans: A significant number of reviewers recommend the game to fans of Warhammer 40K, Adeptus Mechanicus, and Necrons. The game appeals strongly to the existing fanbase.

Wait for sale: A substantial number of reviewers recommend waiting for a discount or sale before purchasing, indicating perceived value issues or quality concerns.

Prefer first game: Many reviewers advise playing the first Mechanicus game instead, either because they consider it superior or because they want a similar experience. This is a common negative point.

Enjoyable for first-game fans: Some reviewers state that players who enjoyed the first game will likely enjoy this one, viewing it as a worthy continuation.

Buying context

Community fair range: $20.00 - $30.00.

Game completion: 60.0h.

Story completion: 25.0h.

The opening hours are a tutorial-heavy, linear slog, but most reviewers report the game becomes engaging after the tutorial and early progression unlocks, around two hours in.

Reported time to anchor: 2h.

Friction: Tutorial is linear and overlong; Early game lacks meaningful customization; Repetitive missions and identical objectives; Leader survival constraints force cautious play; Poor explanation of progression mechanics; Boring starting leaders.

Unlock drivers: Skipping the tutorial; Skill point allocations; Unlocking better units and tech tiers; Campaign map opening up; Mid-to-late game lord and Dominion abilities.

Player profiles

Disillusioned Veteran: They prefer building custom tech-priests, exploring labyrinthine missions, and optimizing squad loadouts; they find the new leader-locked system restrictive. Motivation: To recapture the depth and atmosphere of the first game, but they are repeatedly disappointed by the sequel's design and bugs. Stance: no buy.

Adaptive Sequel Enthusiast: They experiment with different leaders, adapt to the assignment system, and value tactical variety over deep customization. Motivation: To master the distinct playstyles of each leader and find synergies within the new system. Stance: sale.

40k Lore Devotee: They engage deeply with the narrative, cutscenes, and faction-specific content, and are less focused on optimal builds or meta. Motivation: To experience the 40k setting, especially the Mechanicus and Necron factions, in an interactive tactical game. Stance: buy.

Platform notes

Performance reports across Windows hardware tiers are highly inconsistent; some players run the game smoothly at high settings while others suffer from severe FPS drops, stuttering, and high GPU usage, indicating optimization issues that affect a wide range of configurations.

Windows 8-11GB VRAM: mixed. Performance is divided, with some players reporting smooth gameplay after adjusting settings and others experiencing 10-30 FPS and frequent freezes.

Windows 12-15GB VRAM / 16-31GB RAM: mixed. Players report both excellent performance (80-100 FPS maxed) and severe issues like 10-40 FPS and stuttering at low settings.

Windows <8GB VRAM / 16-31GB RAM: mixed. Experiences vary widely, from no issues at 60 FPS to constant GPU maxing and frame drops below 40 FPS.

Steam Deck: The Steam Deck experience for this title is mixed. It is playable but requires significant manual tinkering with graphics settings and performance troubleshooting to achieve stable frame rates. Small UI text and occasional crashes/black screens add friction, while controller support is partially incomplete. Recent optimization updates have helped some users, but stability remains a concern, especially in later campaigns. Overall, the game is not seamless out of the box, but it is not completely broken either.

Linux and Proton: Linux user feedback is overwhelmingly positive. The game launches reliably on Proton, performs well on high-end hardware, and requires only minor adjustments such as choosing Proton Experimental/GE or disabling a single graphics option. No significant Linux-specific blockers or anti-cheat/DRM issues were reported.

Extra review signals

Monetization: The primary monetization issue raised in the reviews is a paid DLC that restores the original game's soundtrack, which players describe as a cash grab and an artificial downgrade of the base experience. No pay-to-win, loot boxes, or aggressive microtransactions are mentioned. Most other complaints relate to base-game price, quality, or technical issues, which are not monetization evidence.

External guides: The feedback indicates that players occasionally rely on wikis or search engines to understand game mechanics, remember spawns, or cope with localization issues. However, none of the complaints match the strict keywords for higher tiers (farming, drops, inventory, crafting, quests, mechanics, etc.), so the overall external data dependency is assessed as low.

Other review notes

Downgrade from Mechanicus 1: Many reviewers compare this game unfavorably to the first Mechanicus, citing downgrades in music, mechanics, and overall polish.

Sequel differs from original: The game is recognized as a sequel that introduces significant changes to gameplay and structure, which some find refreshing while others find disappointing.

Sequel fails expectations: Fans of the first game may be disappointed, as the sequel does not meet the high bar set by the original, leading to negative comparisons.

First game soundtrack sold as DLC: Players criticize the practice of selling the original game's soundtrack as paid add-on content in the sequel, seen as exploitative.

Rushed development suspected: Evidence suggests the game was rushed to meet a deadline, likely the Skulls event, leading to a less polished product.
