Owlcat Games used its slot at gamescom 2026 to answer a question that matters more in a party-based RPG than almost anything else on a feature list: who is going to be talking at you for the next hundred hours.
A new Voice Over Reveal Trailer for Warhammer 40,000: Dark Heresy introduces the first wave of the game's companion cast, naming seven actors and, more usefully, seven of the characters who will be riding along with your Acolyte through the Calixis Sector. Owlcat is explicit that this is only the first batch - more allies and, in its phrasing, more notable names are still to come.
The seven names
The reveal pairs each actor with a companion and, critically, with an archetype - which tells you a fair amount about the party composition Owlcat is building toward.
- Aaron Sinn as Haymar Devos, a Catachan Jungle Fighter
- Jonathan Cox as COGG, Conscript 0-118-B
- Britaney Chanel as Epione Spes, a Chirurgeon
- Stephen Spencer as Saro, a Sanctioned Psyker
- Rhiannon Moushall as Ra'akhti, a Kroot Huntress
- Chris Sharpes as Laarthyr Cairnareth, an Aeldari Corsair
- Ian Russell as the Servo-Ossuarium
Sharpes is a returning face for anyone who played Rogue Trader - he voiced Pascal Haneumann there, and turns up here as an Aeldari corsair, which is a considerable tonal jump.
What the roster tells you about the game
Read the list as a party sheet rather than a credits roll and the shape of Dark Heresy gets clearer. A Catachan Jungle Fighter is a frontline body from a death world. A Chirurgeon is a medic. A Sanctioned Psyker is the sanctioned-and-therefore-only-mostly-dangerous magic slot. A conscript designated 0-118-B is, by the naming convention alone, someone the Imperium considers disposable.
Then there are the two that raise eyebrows. A Kroot Huntress is a xenos mercenary. An Aeldari Corsair is a xenos pirate. Both are travelling with an agent of the Inquisition, which in Warhammer 40,000 terms is roughly like a narcotics officer keeping two cartel enforcers on retainer - workable, deniable, and a hanging offence if the wrong superior finds out. Owlcat's previous 40K RPG, Rogue Trader, made a lot of narrative mileage out of exactly that tension, and Dark Heresy is starting from a position where two of your first seven named companions are things the God-Emperor's servants are supposed to shoot.
The Servo-Ossuarium is the outlier - a bone-and-machinery construct with a voice actor attached, which suggests it is a character rather than a prop.
The pitch, restated
Dark Heresy casts you as an Acolyte of the Inquisition rather than a Rogue Trader or a Space Marine, and Owlcat has been consistent that the register is detective story first, war story second. You lead investigations, unpick conspiracies, and fight a quiet war against heresy, xenos infiltration and corruption inside the Calixis Sector - with the Tyrant Star anomaly and the Night Lords named as threads running through the narrative.
Mechanically it is a party-based, story-driven cRPG with turn-based tactical combat, which is the house style Owlcat has now built across Pathfinder: Kingmaker, Pathfinder: Wrath of the Righteous and Rogue Trader. The Steam description leans on the phrase that has become the studio's signature: tough choices, made as a conduit of the God-Emperor's will.
Still no date
Owlcat has not attached a release window or a full platform list to this reveal. The game has a Steam page listing Owlcat as both developer and publisher, and the store entry still reads "coming soon". The trailer itself carries the studio's standard development-footage disclaimer.
Owlcat is running an unusually busy year - The Expanse: Osiris Reborn and Shadow of the Road both had gamescom showings of their own this week - so Dark Heresy naming its cast rather than its date is not especially surprising. The cast reveal does, however, mark the point where the game stops being a premise and starts being a party you might actually want to travel with.
Warhammer 40,000: Dark Heresy is in development at Owlcat Games. No release date has been announced.
