The Horus Heresy: Betrayal at Calth is Out Now in Early Access

Warhammer 40K conquers VR in The Horus Heresy: Betrayal at Calth.

Today, independent game developer Steel Wool Studios unleashed The Horus Heresy: Betrayal at Calth onto Steam Early Access. This turn-based strategy game introduces the Warhammer 40,000 universe to the realm of virtual reality, boasting cross-platform play for both PC and VR. The Early Access build features the first act of the single player campaign, along with four multiplayer levels.

Based on Games Workshop’s tabletop game Betrayal at Calth, this new virtual installment from Steel Wool takes players to the Horus Heresy era on planet Calth. Players take on the role of a tech priest named Magos Ohmnal Sarce who gets caught amidst an internal battle between Space Marine forces.

During the campaign, your goal is to guide units of Space Marine Legionaries through underground arcologies of the planet Calth. In multiplayer, you can suit up as either an Ultramarine or Word Bearer, battling it out across four maps in deathmatch and other objective-based game modes. Multiplayer PvP also supports cross-platform matchmaking, allowing players to queue up against others on either VR or PC.

The most exciting aspect of The Horus Heresy: Betrayal at Calth is its VR Mode, which features a “human-scale” perspective that brings you up close and personal with colossal Space Marines. Such a viewpoint certainly sounds epic, if not a bit overwhelming. 

The Horus Heresy: Betrayal at Calth is available now in Early Access on Steam for $29.99, which is currently marked down for 25% off until March 6. The game can be experienced in VR using both the HTC Vive and Oculus Rift headsets. To get a closer look at the immersive 40K action, be sure to check out the Horus Heresy: Betrayal at Calth gameplay trailer above.
