A connected BIS UI suite.
Our next focus is building out the UI ecosystem, with a full Gameplay Ability System planned as its gameplay foundation. Standalone Spine Armor is also being prepared.
See the planned roadmap ↗Every product has its own requirements, media, and included-content details on Fab. Check the listing before you buy.
Browse all six products ↗Building the whole RPG backbone.
Our first priority is a connected BIS UI suite. The planned full Gameplay Ability System (GAS) would provide a foundation for later abilities and combat work. These are future products and integrations—not features included in today’s Action Bar, Inventory, or Character & Equipment purchases.
BIS Menu Essentials
A common home for menus and navigation across the BIS suite. We currently hope to offer this one free; final scope and pricing are not set.
Full Gameplay Ability System
Planned GAS-based ability, attribute, and effect infrastructure before we build the deeper spellbook and combat integrations.
Abilities & Spellbook
Player-facing ability selection and management, designed around the planned gameplay foundation.
Targeting & Combat
Target selection and combat-facing UI, with gameplay integration scoped against the ability system.
Dialogue & Interaction
Conversation and interaction flows for characters and objects in the game world.
Quests & Objectives
Interfaces for tracking goals, quest state, and player progress.
Chat & Social
Player communication and social UI, with any online service requirements to be defined before release.
Spine Armor
The standalone set and individual pieces are being prepared for Fab. Each still needs its own package, fit, documentation, and media checks.
This is a direction of work, not a release schedule or promise of included features. Order, scope, pricing, and availability may change. See each live Fab listing for what is actually supplied today.

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.
