The MU Project
The classic MMORPG, remade
The classes, maps and events you remember, with today's graphics, interface and security.
What is The MU Project?
A fantasy MMORPG inspired by MU Online. You level up, evolve your class, upgrade your gear with jewels and take on events with other players, just like always. Everything around it is what changed.
The essence, intact
Lorencia, Devias, Noria, Blood Castle, the Chaos Machine and excellent and ancient items.
Looks and plays like today
Shadows, water reflections, reworked item glow, draggable windows and five languages.
Authoritative security
The game decides every hit, every drop and every purchase: tampering with the program gives no advantage.
Three families, nine classes
Every character evolves twice through quests and then keeps growing in the Master Tree.
