The Malstrain is an insidious mutation of the Genestealer Curse. Experiments meant to create a vaccine against the xenos plague merely warped it into something new and terrible, an alien cancer that still lurks within Hive Secundus. The Genestealers of the Malstrain are terrible evolutionary missteps possessed of extreme speed and aggression, capable tearing a full-grown Goliath into bloody meat in seconds. They accompany the gangs and Brood Scum they have infected, joined by Malstrain Tyramites – overgrown insectoid parasites, bloated on Malstrain infection, who follow their chosen masters like faithful chittering hounds.

This multipart plastic kit allows you to build your own Malstrain or Malstrain Corrupted gang, including six Malstrain Genestealers and four Malstrain Tyramites. Each of the Malstrain Genestealers sports razor-sharp claws and a range of head options, including drooling tongues, barbed ovipositors, and tentacles. The Malstrain Tyramites float around after them, with two tentacle options and two bodies. The kit also includes 10 mutated heads for creating Brood Scum, designed to be used with the Hive Scum models, which are sold separately.
