Swooping on leathery wings, Parasites of Mortrex use their barbed ovipositors to drive Ripper gestation pods deep into their victims’ bodies. These swiftly-growing creatures soon chew themselves free from their unfortunate hosts. Such was the fate of the defenders of Imperial planet of Mortrex, the world first cursed by the Parasites’ onslaught. Now they wreak havoc on the foes of the Hive Fleet by soaring over defences and seeding unlucky souls with nascent Rippers.
