Compare Warhammer 40,000: Gladius - Adeptus Mechanicus (DLC) prices across trusted key stores and find the best deal. Developed by Proxy Studios. Published by Slitherine Ltd.. Released on 11/22/2021. Available on PC. Genres: Strategy.

The Adeptus Mechanicus arrive on Gladius Prime with a tech-worship playstyle unlike any other faction in the base game. Expect a steep mechanical curve and a rewarding late-game payoff.

Warhammer 40,000: Gladius - Relics of War is a 4X strategy game that strips the genre back to warfare, with almost no diplomacy to soften the blade. This DLC adds the Adeptus Mechanicus as a playable faction, and they are not a reskin of anything already in the box. The Cult Mechanicus operates on a distinct resource and upgrade philosophy rooted in their lore: they worship the Omnissiah, the machine-god, and that obsession translates directly into gameplay mechanics built around knowledge acquisition and technology retrieval rather than raw expansion. Where factions like Space Marines or Orks push you toward aggressive early momentum, the Adeptus Mechanicus reward a more deliberate, infrastructure-heavy opening. Their units lean into Doctrina Imperatives, toggle-able combat stances that shift stat profiles mid-battle, giving you a layer of tactical decision-making that most Gladius factions simply do not have. Skitarii Rangers, Kataphron Destroyers, and the hulking Kastelan Robots each fill distinct combat roles, and learning which Doctrina loadout to run in a given engagement is the real skill expression here. The faction does not forgive sloppy early-game play, but once the engine turns over, the unit roster scales hard. The DLC slots cleanly into both single-player and multiplayer modes, including the cross-platform and LAN co-op options the base game supports. In a competitive multiplayer context, the Adeptus Mechanicus occupy a high-skill-ceiling slot: opponents who know the faction will find the Doctrina Imperatives genuinely disruptive to counter, while a player still learning the rhythm will hemorrhage units in the mid-game. For solo skirmish players, the AI running this faction is at least as competent as the base-game factions, which is a meaningful bar given Gladius already runs a reasonably aggressive AI difficulty ladder. The value proposition here depends entirely on how deep you are already in Gladius. If you own the base game and have cleared out a few campaigns, the Adeptus Mechanicus offer the most mechanically distinct playstyle in the roster at time of writing. If you are a newcomer considering stacking DLC on a first purchase, hold off until you have the core faction loop down, then come back. The tutorial does not meaningfully cover the Doctrina system, so expect to learn it from the wiki or from losing. Steam Workshop support is present in the base game, which means the modding community has had time to produce supplementary guides and balance tweaks that make the learning curve more manageable. Check the Workshop before your first campaign run. The Adeptus Mechanicus DLC is a focused, lore-coherent faction addition that earns its place in the roster through genuine mechanical differentiation. It is not a casual pick-up, but for the Gladius player who wants a second or third distinct strategic identity to master, it delivers exactly that. Diego, Scout Team

Every store in this table quotes us in euros, so the EUR figure is the price the seller actually set, not our arithmetic — which is why EUR is also the currency we rank in. We only list an offer here when the store gives us its price in euros, so nothing in this table is a number we invented.

Pick USD, PLN, GBP, CAD or AUD in the header and we convert from EUR at the European Central Bank reference rate — converted amounts are prefixed with ~. Your bank or the store may apply a different rate at checkout. We never hide offers based on where you are: everyone sees this whole table.

We may earn a commission when you buy games through links on this page — at no extra cost to you. It never affects our rankings or verdicts.
