About Black Iron Spine Studios

A workshop for game creators.

We're a small independent studio building practical tools for Unreal Engine developers. Our first releases cover action bars, inventory, navigation, loot, vendors, and the connections between them.

Our long-term ambition is a hardware store for game development: a growing catalog of gameplay systems, character gear, 3D assets, and modular building pieces. We're building it one useful release at a time.

Available nowGameplay systems

Explore seven available RPG tools and integrated kits on Fab.

Available nowCharacter & equipment

The Draugr characters, Spine Armor and RPG Character & Equipment Kit are live. Check each listing for exact contents and compatibility.

Future catalog3D assets & modular builds

We aim to add game-ready props and flexible building pieces over time.
