Classic tanks from the Forge World range return to the Horus Heresy at the Games Workshop webstore, upgraded with new plastic sponson sprues that make it easier than ever to add weapon variety to your armoured companies.
The various resin models, such as the Mastodon Heavy Assault Transport, will now come with the sponsons sprue that is available now with the plastic releases that we have seen.
There is an implication here that future Horus Heresy releases may now be resin models. Especially as the only preview we have seen over recent months has been the Vindicator.
Though that may also mean that the Legion models we have seen, will now be supplemented with plastic releases for other Horus Heresy forces, such as the Solar Auxilia.
