The Horus Heresy: Betrayal at Calth

The Horus Heresy: Betrayal at Calth is a turn-based tactics game developed by Steel Wool Studios for VR and standard screens. Released in 2020, the game adapts the board game depicting the Word Bearers' betrayal of their Ultramarines brothers in the tunnels beneath Calth. The brutal civil war between Space Marines comes to life in tactical combat.

The gameplay follows the board game rules faithfully. Space Marines battle Space Marines in narrow corridors where action points, cover, and special abilities require tactical thinking. VR support makes the experience more immersive for those with compatible hardware.

The campaign follows the board game's story with both sides playable, offering different perspectives on the betrayal. The graphics were solid for an indie project, capturing the claustrophobic underground warfare effectively.

Betrayal at Calth found a small but loyal fanbase among Horus Heresy enthusiasts. The VR option was an interesting experiment, though the technology had limitations. It provides a unique way to experience one of the Heresy's most pivotal moments.
