Tyranids invade the galaxy from beyond the intergalactic void, their hive fleets slithering into every system and sector. The Vardenghast Swarm is a clutch of Tyranid organisms that has reaped a bloody toll of prey, categorised as an alpha-class threat by Imperial cryptosavants after a series of brutal battles along the Vardenghast Line. Flowing into the fight like a single, many-bodied entity, these vicious aliens swiftly close the distance to their enemies before riddling them with gruesome bio-ammunition or tearing them limb from limb.
