About Zaikan MU
What this server is, what it has that the others do not, and what to expect from it today.
Updated on August 10, 2026Zaikan MU is a Mu Online Season 6 Episode 3 server, the same Season 6 you played years ago, with Season 20 imported piece by piece on top of it. Maps, classes, skills, weapons, armor and wings that Webzen released after the third class were brought over with their original numbers, inside a game that is still the classic one.
This is not a server running purchased files. Both the server and the client are developed and compiled by our own team, which means anything you see here, from the damage formula to the way a window is drawn, can be changed. And it was.

What exists here and nowhere else
Most Season 6 private servers ship the same content package, with the same items and the same maps. What sets Zaikan apart is what was built on top of it.
- Fourth and fifth classes in full, with their official names, from Dragon Knight to Bloody Fighter.
- Two independent point trees: the third class master tree, and the fourth class Enhance Skill Tree on the N key.
- Ten tiers of mastery armor, from Bloodangel to Lightning, plus 130 top end weapons and shields.
- Fourth and fifth generation wings with the values from the official tables.
- New maps: Ferea, Acheron, Debenter, Urk Mountain, Nars, Nixie's Lake and the five Deep Dungeons.
- The whole interface redesigned, window by window, draggable, with rarity colors and gear score.
- Farming spots marked on the minimap of the classic maps, with automatic travel to the point.
- Minimap in a window with zoom, dragging and click to walk.
- Our own launcher that updates the client by itself.
- Post processing with bloom, per map fog and antialiasing, all of it switchable.
How the game is split
The journey has three clearly different blocks, and it pays to understand this before creating your character, because each block asks something different from you.
- 1 to 400The classic game
You level up killing monsters, changing maps every few levels and putting together your first decent set. You go through the first two class evolutions and finish with wings and a full set.
- Master 1 to 400The master skill tree
Level caps at 400 and experience starts turning into master level. Each master level gives one point to the third class tree, which is where skills get truly strong.
- Total 800+Fourth class and endgame
At total level 800 you take the Cent trial and become fourth class. That opens the second tree and the mastery gear, which run all the way to total 1500.
The state of the server today
Zaikan is in closed testing. This matters and we would rather spell it out: the server is up and playable, but content still changes often, bugs show up and characters may be wiped before the official launch.
- Experience rates are tuned for testing and are not the launch rates.
- Some monsters are temporarily weaker to make testing new content easier.
- Systems marked as pending in this wiki really do not work yet. No page here promises anything that is not live.
