Warhammer 40,000: Dark Heresy has a new trailer fresh from IGN Fall Fan Fest 2025, and it confirms a Q4 2025 release window for the alpha.

Owlcat Games’ promising follow-up to cRPG Warhammer 40,000: Rogue Trader, lets players become an acolyte of the Inquisition, one of the Imperium’s heresy-hating enforcers. Here’s the official blurb:

Step into the shadows as an acolyte of the Inquisition in Warhammer 40,000: Dark Heresy, a second narrative-driven tactical RPG set in the beloved grimdark universe. Set against the backdrop of the Noctis Aeterna and the mystery of the Tyrant Star, players will lead a warband of diverse companions in a desperate battle against heresy and corruption — from loyal Imperial subjects, such as a veteran Guardsman from the death world of Catachan, to nefarious xenos, including a bird-like Kroot mercenary.

With intricate investigations, a turn-based combat system, and choices that carry grave consequences, Dark Heresy is set to deliver an atmospheric dive into the brutality and mysticism of one of the Imperium’s most feared organizations. The game greatly expands on the ideas introduced in Rogue Trader and features fully voiced dialogues.

Warhammer 40,000: Dark Heresy is due out on PC (Steam, GOG, Epic Games Store) and PlayStation 5 and Xbox Series X and S. There’s no release date yet, but thanks to the new trailer, we know we’ll be able to play the game before the end of this year.

Meanwhile, also at Fan Fest, Owlcat announced a Nintendo Switch 2 version of Rogue Trader. It’s exciting times in the world of Warhammer 40,000 video games. Not only do we have Dark Heresy and the Switch 2 launch of Rogue Trader to look forward to, but we also have significant updates still coming to the likes of Darktide and Space Marine 2. Looking further ahead, Warhammer 40,000: Mechanicus II, Dawn of War 4, and Space Marine 3 are all in the works.
