The Horus Heresy Betrayal at Calth — is a turn-based tactical strategy in the Warhammer 40k universe. The game features both a story campaign and multiplayer battles. Despite the step-by-step gameplay, even waiting for the opponent’s actions, you can observe colorful battles thanks to the A Living Battlefield function. The first shots of the conflict thundered, which will change the future of mankind. The legions of the Space Marines oppose each other, the noble Ultramarines are betrayed on Calt by the legion of the Word Bearers. A dark ritual stirs up confrontation, and the battle is for honor, faith, devotion to the Imperium, or simply for survival. The project can work both in normal mode and in VR, and multi-user interaction is possible between players using different modes.
