Cross-platform professional game development tools, resources, community & support for:





Attribute Tag Engine
Zero-allocation state and action system built on a raw flat-memory substrate. It uses bit-packed columns and branchless vector loops to evaluate deterministic logic and utility AI across hundreds of thousands of concurrent actors.
DataLens
A cache-aware in-memory simulation database for massive actor systems. It uses bit-packed, column-major arrays to orchestrate a small, hot gameplay viewport over millions of rows of raw data.
Toolkit for Discord Social
Bring rich presence, lobby join, invites, voice, and more to your game.
Our newest Toolkit supporting Discord’s new Social SDK.
Gameplay Tags
A structured, hierarchy-aware GameplayTag system built for performance and ease of use. Every node, every option, every stat and item can be identified with a human-friendly tag. Tags organise by dot-path and can be searched, set, tested and have values.
Lexicon Localisation
A localisation tool that goes beyond spreadsheets and chat bots. Lexicon allows you to localise anything — text, sound clips, images, models, and any other asset your engine uses. All keys are tagged and referenced by GameplayTag, so every piece of localised content is discoverable and trackable.



Ogham Storyteller

Seamlessly integrated with GameplayTags and Lexicon Localisation, your stories are natively part of the game. All content is localisation-aware by default text, audio, images, prefabs, etc.
Toolkit for Steamworks
The complete Steam toolkit for Unity and Unreal. Covers every feature of the Steamworks SDK and is available on both engines.
