About this game

MU Bug Online — Action MMORPG for Android

Immerse yourself in a medieval fantasy world with real-time combat, hundreds of creatures and bosses to face, and a deep class system to forge your own playstyle: Dark Warrior, Dark Knight, Elf, Magic Gladiator, Dark Lord, Summoner, and Furious Fighter — each with its own skill trees and builds.

Controls designed for mobile, not a forced port. Virtual movement joystick, touch-sensitive combat buttons, one-tap target lock, and a quick skill selector so you don't waste time between attacks. Items and potions are automatically assigned to hotkeys as soon as you pick them up, so you never miss a beat in combat.

Progress even when you're not playing. The Offline Level Helper keeps farming experience for you while you're offline — log back in and find your strongest character.

A living world, not just dungeons. Form a guild, join a party, trade with other players, duel to test your build, and follow the global chat so you don't miss a thing. The minimap and the Events & Bosses window will tell you where the action is at any given moment.

Explore classic maps—Lorencia, Devias, Noria, Lost Tower, and more—each with its own unique atmosphere, monsters, and secrets.

No intrusive ads. No forced pay-to-win. Just you, your build, and a world to conquer.
