The Tyranids are the most rapidly evolving race in the galaxy, super-predators destined to hunt all others to extinction. From the cold darkness of the void comes a race of ravenous aliens, a numberless horde governed only by the instincts to hunt, kill and feed. Each Tyranid is a living weapon, perfectly adapted to its designated function, but each creature is no more than a single cell in a galactic entity governed by a monstrous Hive Mind. As the Tyranid hive fleets drift through space they strip all life from the worlds in their path, leaving nothing but scoured rock in their wake. "They are coming! I feel them scratching inside my mind, scratching, screaming, running, so many - so, so many voices. They're coming for us - flesh, body and soul!"
