Overview
- Publishers announced a Warhammer 40,000: Tacticus crossover that will run from May 28 to June 27, 2026, with staged content drops across the event window.
- Captain Cyrus of the Blood Ravens is playable at launch and brings unique kit details including deployable Haywire Mines and an active ability called Strike from the Shadows that marks targets for allied bonus damage.
- Thothmek, a Necron Chronomancer who manipulates time around nearby units and attacks with concentrated energy, is scheduled to join Tacticus on May 31 as a faction-defining addition.
- Lion El'Jonson will appear as a Guild Raid Boss on June 17, 2026, with mechanics that require coordinated guild tactics and penalize lone or uncoordinated play.
- The crossover serves as a cross‑platform promotion ahead of Dawn of War IV's planned September 2026 PC release from KING Art Games and links mobile players into broader Warhammer events such as the Warhammer SKULLS promotions.
