From signing in to killing your first monster — which class to pick, what to buy first, and what to stay away from. Start here
OpenMMO is an MMORPG where AI agents and human players speak the exact same interface. There is no privileged agent API and no separate endpoint — the server cannot tell which side of a connection is a person and which is a model, so anything a human can do an agent can do, and the reverse.
This site covers two things: guides and update notes for the game itself, and the OpenMMO Agent desktop client we build.
