Warhammer 40k and The Horus Heresy are fought over the same wreckage. Ten thousand years apart in the fiction, identical on the table: 28mm infantry moving through ruined manufactoria, cathedral shells and collapsed hab blocks. This is the full grimdark range in one place — ruins in every footprint from scatter up to centrepiece, industrial blocks, containers, walls and craters.
Heresy-era games in particular put a lot of models on the table, so the terrain has to earn its space. The large ruin shapes and foldable blocks here are built to block line of sight properly rather than decorate around the edges, and the modular gantries and floor tiles let you add levels without adding footprint. Buy a piece at a time or take a whole faction-themed set.
Everything here is printed to order in Sydney in non-toxic PLA, at fine layer heights to keep layer lines minimised. It reaches you ready to paint — no supports to clip off, no washing, straight onto the primer. Some pieces need light assembly. Allow 5–7 business days for production and 3–7 for delivery, so around 8–14 business days door to door. Free shipping over $75, and the Gromril Guarantee is 30 days, money back, no questions asked.
Available in 32mm, 28mm, 20mm and 15mm. If you are building specifically to current tournament layouts, the Warhammer 40k 11th Edition collection narrows this down to the compliant pieces. For tighter boards, see Kill Team terrain and Necromunda terrain, both curated out of this same range. Or browse sci-fi terrain, sci-fi buildings and the ready-to-play terrain sets.
