Warhammer 40,000: Inquisitor - Martyr casts the player as an agent of the Imperium in the embattled Caligari Sector, where Chaos is corrupting worlds beyond the Emperor’s reach. Its story campaign follows investigations and missions tied to a haunted fortress-monastery and a secret from the Inquisition’s past. The grim setting frames the game as an action RPG about carrying out the Inquisition’s brutal work, rather than a conventional military campaign.
Character choice shapes how that work unfolds. The Crusader can hold ground against incoming enemies, the Death Cult Assassin brings a focus on finesse and cunning, and the Primaris Psyker draws on the Warp. Missions pair tactical combat with destructible environments and cover, while executions feature in boss battles. Across the sector, the Star Map leads to varied locations, from planets with distinct terrain to infested Void Stations and abandoned Star Forts. Uther’s Tarot lets players set mission conditions, with crafting and skill adjustments offering further ways to prepare a loadout.
The game supports both solo play and cooperative missions with friends, accommodating up to four team members; players can also join Cabals, which progress and may grant special missions. Its broader structure combines a persistent sector, varied missions, character specialization, and equipment tuning into an ongoing Inquisitorial campaign.
