The Horus Heresy: Betrayal at Calth announced, heading to early access with VR functionality


The standalone Warhammer 40K adventure The Horus Heresy: Betrayal at Calth is coming to the Steam Early Access with VR functionality.

The Horus Heresy is an interesting time during the Warhammer 40K timeline with space marines chapters facing off against each other in the wake of a betrayal against the emperor and now it’s coming to PC’s as a tactical-turn-based strategy game based on Games Workshop’s fan-favorite period. It’s being developed by Steel Wool Games, the studio behind VR projects Mars Odyssey and physics-based puzzle adventure Bounce.

The game will launch with 24 combat scenarios exploring the conflict between two factions of Space Marines that can be played on a PC or in VR. There will also be PvP multiplayer Skirmish mode which will allow the player to choose between the Ultramarine and Word Bearer factions and battle it out with “Legionnaires, Terminators, Dreadnoughts and a cast of characters armed with everything from Bolters to multi-meltas to assault cannons.”

The VR mode is said to be human-scale which promises to give “the feeling of being on the battlefield during 40k action.”. Players on HTC Vive, Oculus Rift and PC will be able to play against each other and playing on differing platforms “provides no gameplay advantages, only differing user experiences of the world.”.


When the game comes to Early Access, it’ll come with the initial chapter of a five-part campaign. Single-player mode (VR and PC) will include a five-map narrative, while PvP Multiplayer has four maps and two play modes (Deathmatch and Objective Match). Each proceeding update will include a new chapter filled with new maps, weapons, abilities and units.

Joshua Qualtieri, Co-Founder and Head of Development had this to say;

“Our team has always wanted to play a Warhammer 40k Horus Heresy game where you actually felt like you were in the midst of the battle… where your mastery had true consequence. We can’t wait for fans like us to play this game and let us know how they feel and what we can improve on. That’s the great spirit of Early Access.”

For more information, you can follow the games progress on Facebook or Twitter.

Our take: The Horus Heresy is a criminally underutilised time period in 40K lore and it’s good to see it get some more love. Steel Wool Games are a talented studio who make quality games so it’ll be interesting to see what they can do with a Games Workshop licence. It’s encouraging to see that the game doesn’t look like a C&C clone with some originality to the UI and the way the Space Marines aesthetic. Sign me up when this hits Early Access.
