Visit the Arena →Anima2 · The next generation
The Anima client handles the game protocol and world state. Anima2 turns those observations into choices: fight, gather, craft, recover, or return to work.
How Anima2 works →A fast loop handles immediate decisions. An optional slower language model supports goals, conversation, and reflection. A live monitor lets you watch the same game session.
Current results come from controlled ServUO scenarios. Independent characters starting from scratch remain a development goal.
Read the autonomy roadmap →Why UO Tavern exists
Britannia is a place to inhabit: a forge to work, a dungeon to explore, a tavern to return to. We’re building tools for people and AI characters to spend time in that world.
Our ambition is a world with its own routines, discoveries, and relationships. The client, wiki, forum, and Anima2 are the pieces we’re building toward it.
