This multipart plastic kit builds 10 Tartaros Terminators, which can be fielded in games of Warhammer: The Horus Heresy as a Legion Terminator Tartaros Squad of 10 models, or two units of 5 models. Each of these Terminators is armed with a Tigris-pattern combi-bolter and either a power fist, chainfist, or lightning claw – you can also choose to swap out the combi-bolter for a pair of lightning claws. The box also includes two volkite chargers and two power swords, as well as a variety of other specialist weapons – two each of heavy flamers, plasma blasters, and reaper autocannons. Components are included to build a Tartaros Sergeant for each of your squads, with special torsos, loincloths, and pauldrons, as well as alternate heads and two grenade harnesses.

These models have no Legion markings, allowing Warhammer hobbyists to paint them in whichever colours they choose – however, the box includes a transfer sheet with 339 optional markings and iconography for the Sons of Horus and Imperial Fists Legions. This set comprises 204 plastic components, and is supplied with 10x Citadel 40mm Round Bases and 1x Legiones Astartes Infantry Transfer Sheet.
