Warhammer 40,000: Battlesector – Deeds of the Fallen is a 2025 turn-based tactical strategy expansion for PC, set within the conflict-torn Warzone Chalnath. The campaign takes players to the planet Thorakleo IV across 12 new missions, continuing the broader galactic war that frames the base game. The expansion focuses on the Sisters of Battle faction, adding three new units to their roster and expanding the tactical options available when commanding that force. As with the core Battlesector experience, gameplay centers on grid-based, turn-by-turn tactical combat set in the Warhammer 40,000 universe. Deeds of the Fallen serves as a focused content addition for players already invested in the Sisters of Battle, deepening both the narrative scope of the Chalnath warzone and the mechanical variety available to that faction on the battlefield.
