Tyranids come in a shocking variety of forms, each more terrible than the last. Small disruption forces have been observed, led by a so-called Parasite of Mortrex. Forces are protected by slab-armoured Tyrant Guard and supported by walking artillery known as Biovores, who lob living spore mines high across the battlefield. Perhaps the most dangerous element is the aggressive and stealthy Genestealers, rushing forward to rend and tear with long, razor-sharp claws.
