Commanding Leman Russ tanks and grinding infantry formations is lore-accurate fantasy, but the mixed Steam reviews on this DLC are a real warning sign worth understanding before you spend.

I track faction DLC the way some people track patch notes, so when the Astra Militarum finally marched into Battlesector I was ready to spreadsheet the whole thing. The base game earns its Very Positive rating honestly: it is a fast turn-based tactics title with one of the smartest mechanical hooks in the genre right now. The Momentum system rewards aggressive play by building a meter through kills and efficient action use. Fill it, and you choose between Surge (an extra action point) or Empower (a boosted ability). Passive players get penalised with meter losses for going on Overwatch or wasting action points. It punishes passivity in a way that feels genuinely designed rather than bolted on, and it is the reason the base game holds up. The Astra Militarum DLC brings sixteen new units into that framework, and on paper the roster is exactly what Guard fans want. The Cadian Castellan issues orders and directs fire, the Tank Commander leverages armoured synergy, the Commissar manages frontline morale, Cadian Shock Troops and Heavy Weapon Squads form the infantry core, and then you have the heavy metal: Leman Russ tanks, the Basilisk with its Earthshaker Cannon arcing shells over cover, the Rogal Dorn anchoring defensive lines, and Armoured Sentinels picking vantage points across rough terrain. Ogryns provide blunt melee muscle, the Primaris Psyker brings psychic firepower, and the Kasrkin serve as assault specialists for trickier objectives. On unit variety, the list is solid. Where it gets complicated is implementation. Community feedback is split almost down the middle on the DLC specifically, sitting at roughly 48% positive in standalone reviews even though the overall game sits at 87%. The honest diagnosis: infantry platoons can feel interchangeable across several mission types, and the combined-arms fantasy of artillery plus armour plus foot soldiers does not always produce the satisfying tactical chain you expect. The Commissar's morale mechanic, faithful to lore, ends up feeling like an incremental number rather than a moment of dramatic leadership. Experienced players note the faction really clicks at higher point thresholds, around 1500 to 2000 points, where the full toolkit unlocks and the Tank Commander becomes a centrepiece rather than a crutch in low-cost skirmishes. For newcomers to Battlesector, the base game remains accessible. The campaign's twenty missions across Baal Secundus are paced well enough to teach the Momentum system without a wall-of-text tutorial, and skirmish modes including the conquest-style Planetary Supremacy and the wave-survival Daemonic Incursion give you structured ways to learn faction nuances at your own pace. The Astra Militarum DLC is best treated as an expansion of your skirmish and multiplayer roster rather than a self-contained content drop. If Guard is your faction of choice at the tabletop and you want that aesthetic in a digital tactics game, the unit models and voice work deliver. If you are buying purely for tactical novelty, the gap between what the lore promises and what the AI consistently executes with the new tools may leave you underwhelmed. Diego, Scout Team

GamerScout Verdict

Best for tabletop Guard players who want the aesthetic in digital form, but expect the combined-arms depth to underdeliver at lower point thresholds.

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.
