Six paths
Choose your class
All open from day one — and each one evolves as you level.
Dark Knight
Evolves into Blade Knight → Blade Master
The front line. Heavy armor, huge health and Twisting Slash combos that keep the party alive and the enemies busy.
Fairy Elf
Evolves into Muse Elf → High Elf
Archer and support. Multi-shot from afar, summons that fight at her side and the attack and defense blessings every party wants.
Magic Gladiator
Evolves into Duel Master
Sword and spell in one hero. Available from day one, he levels fast and hits hard in both styles.
Dark Lord
Evolves into Lord Emperor
A born commander. Fights beside his Dark Raven, rides the Dark Horse and leads guilds into Castle Siege.
Summoner
Evolves into Bloody Summoner → Dimension Master
Curses, sleep and chain lightning. She weakens the strongest enemies and controls the battlefield.
Invite friends, win Jewels of Life
Every friend who reaches level 200 gives you both jewels and Kundun boxes. Bonuses at 3, 5 and 10 friends.
Launch campaign until Nov 14, 2026
Questions
Before you dive in
Everything people ask before their first Play.
01Do I need to download anything?
No. The whole game runs inside your browser tab: no client, no launcher, no installer. The first visit loads about 60 MB of game data, which your browser keeps, so the next time it starts in seconds.
02Does it work on iPhone?
Yes. Open the site in Safari or Chrome on an iPhone or iPad with iOS 26 or newer and turn the phone sideways. Touch controls and an on-screen keyboard for chat and login are built in.
03Is it free?
Yes, completely. There is no subscription and nothing to buy to play. Power comes from playing, not from paying.
04Is my progress saved?
Always. Your heroes, items and levels are stored on our server, not in the browser. Log in from your PC tonight and from your phone tomorrow: it is the same hero.
05Which browsers can I use?
Chrome or Edge on Windows and Linux, Chrome on Mac, Safari or Chrome on iPhone and iPad. Recent Android phones with Chrome should work too. The game needs WebGPU, which these browsers have switched on by default.
06Is this the classic MU?
Yes: MU Online Season 6 with Dark Wizard, Dark Knight, Fairy Elf, Magic Gladiator, Dark Lord and Summoner all open from day one, the master skill tree, Blood Castle, Devil Square, Chaos Castle and the invasions, with fast early levels and resets at 400.
