Warhammer 40,000: Gladius - Adepta Sororitas brings a new faction to the battlefield of Gladius Prime: the Adepta Sororitas, known as the Sisters of Battle. This expansion offers players eighteen new units and distinctive gameplay mechanics centered around devotion to the Emperor. The Sisters are the militant arm of the Adeptus Ministorum, embodying purity of heart and unwavering faith. They serve by tending to the needy, spreading the Emperor's word, and dispensing merciful death to the unworthy.

Key gameplay mechanics include the Shield of Faith, providing units with protection against damage, and Acts of Faith, which allow them to gain temporary combat bonuses when morale is high. The Sisters wield the Holy Trinity of Weapons: Bolters, Flamers, and Meltaguns, while Sacred Rites grant faction-wide bonuses at a cost. The Martyr Spirit empowers nearby units upon a sister's death, while cities earn Loyalty through the Convent of Faith.

With a unique resource system replacing food and ore with requisitions, the Adepta Sororitas stand ready to defend the Emperor's glory in the war for Gladius. Experience a complete roster of units including Canoness, Saint Celestine, and the fearsome Battle Sister, and lead the charge against all who oppose.
