Our story
Born in Lorencia. Rebuilt from nothing.
We are a team of developers who never stopped playing MU Online. We have spent our careers building backends and running game servers, and more than twenty years inside the game itself, since the very beginning.
So we decided to take a step no one had taken before: build the MU Online client from scratch on the Unity engine, and rewrite the server side from the bottom up, every system and every season through Season 21 Episode 3. Not a repack, not a patch on old code. A new foundation, built by players who know how the game should feel.
20+ years
Players since day one
We were there for the first Dark Knights in Lorencia, the first trips to Devias and the first pair of wings. Two decades of MU is the spec we build to.
Backend veterans
Builders by trade
Our careers are backends and live game servers. We know what it takes to keep a world online, fair and fast when it fills up.
Unity client
Written from the first line
A new MU Online client built from scratch on the Unity engine: the world, the interface and the effects you remember, on a modern foundation.
Server rewrite
Every system, every season
The server side rewritten from the bottom up, system by system, all the way to the latest season. No patches on top of someone else's code.
We are building the MU we always wanted to play. Come play it with us.
