Warhammer 40000 Mechanicus Anthology gathers the turn-based tactics game and its additional content into one package, set in the grimdark Warhammer 40,000 universe. Players command squads of tech-priests and servitors through grid-based battles against ancient Necron forces.

The anthology preserves the base game's careful resource management and tactical positioning, offering a fuller look at the Adeptus Mechanicus' battle against an awakening tomb world.
