AXIOM-EMU V2

Everything MU Online should have been.

V2 rebuilds the engine, the interface, the economy and the endgame. 27 brand-new systems on top of everything V1 already did - all configured through XML, all synced to the client, all documented.

Season 6 Is The Base

Not the ceiling. Build whatever era you want on top of it.

Almost every part of AXIOM-EMU is driven by XML - items, monsters, drop tables, shops, quests, chaos mixes, events, skills, talent trees, pets and mounts. Bringing in items, wings, sets, skills and systems from later seasons means editing configuration, not writing C++ or hand-patching client files. Your clients receive the changes at connect time.

The one hard limit: adding a brand-new character class is not possible. Everything else is yours to shape.

01 / 07

Engine & Performance

A rebuilt client and server core. The part nobody else touched.

GameData Sync

Click to enlarge

Only on AXIOM

GameData Sync

Configure once on the server and every client receives it at login. Items, skills, monsters, chaos mixes, talent trees, affixes, combat formulas, potion rates, item level curves - over 40 kinds of game data, compressed and streamed at connect. No client patches, no double maintenance, no version mismatches. Nobody else on the market does this.

60+ FPS

GPU-Powered Render Engine

The original MU client tied everything to 25 frames. AXIOM splits game logic from rendering, then moves the heavy work to the GPU: bones are skinned on the graphics card, particles and effects are batched, terrain draws in a fraction of the time. Boss fights that dropped to 50 FPS now hold 120. Crowded towns full of glowing gear stay smooth.

2

skins, live reload

New in V2

AxiomUI Interface Engine

A brand-new UI engine powers the whole game, from the login screen to the character panel, party, guild, quests, events and every new V2 window. Two skins ship: Classic, a pixel-faithful vanilla look, and Axiom, new painted art with tabbed panels and draggable windows. Layouts are plain XML and images that reload live - restyle your server's interface without rebuilding a client.

7

new graphics effects

New in V2

Next-Gen Graphics

MU Online like you have never seen it. Per-map atmospheric fog, ambient occlusion and contact shadows, colour grading, a retuned glow, and full character shadows with see-through wings. Real water with ripples, foam and reflections - Kalima's sea now shows the cliffs beneath it. Valuable drops light up with coloured loot beams. Every effect is tunable per map and every player gets an instant on/off switch.

300

NPC voice lines

New in V2

Living Sound

Sound finally has a direction. Monsters, skills and NPCs pan left and right and fade with distance. 63 NPCs greet you by voice. 30 maps that were silent got their music back, zones can play random playlists, and music has its own volume. Vanilla played every sound centred and at full volume - across the whole town.

800

fighting bots on 4 vCPU

800 Players / 4 vCPU

Massive Server Capacity

Tested with 800 fighting bots on a 4 vCPU VM - stable. Packets are batched per player, encryption writes straight to the socket, monsters search smarter, and a built-in profiler shows exactly where every millisecond goes. Your hardware bill stays small while your player count grows.

Zero Item Loss

Crash-Proof Persistence

Every item move is saved within two seconds. Chaos Machine items are written the moment they are placed. Saves of one account always land in order, so a relog never brings back an old inventory, and a mass logout can no longer drop queued saves. Crash mid-craft, mid-trade, mid-anything - players log back in and everything is where they left it.

02 / 07

Character Progression

Endgame systems that keep players chasing the next upgrade.

60

talent node effects

New in V2

Talent Tree

The master skill tree, reinvented. Design your own tree in XML: up to 3 categories, tiers, ranks, prerequisites, class filters, and nodes that only work with a certain wing, set, shield or weapon. Around 60 node effects - stats, skill damage, skill upgrades, granted skills, EXP, drop and zen boosts. The whole layout streams to the client, so a new tree is one XML file away. The vanilla Season 6 tree is included, converted and ready.

110

inscriptions

Add-on

Inscriptions

A whole new axis of item power that no other MU server has. Every item rolls a hidden Potential. Spend it at the Chaos Goblin to open slots and carve in permanent inscriptions: flat bonuses, stat conversions, faster casts, debuffs on hit, even unlocking skills while the item is worn. Risky Forbidden inscriptions can corrupt a slot forever. Two identical swords are never the same again.

255

tiers per server

Add-on

Item Tiers

Turn item ranges into named tiers - Rare, Legendary, Mythic - each with its own colour and its own multipliers for excellent, ancient, socket, harmony, 380 and base stats. Nothing is written to the items, so every existing item is tiered the moment you save the file. Tooltips show the scaled numbers and the tier name.

Documentation Add to your license →

+15

levels, fully tunable

New in V2

Item Level Curve

Decide exactly what +1 to +15 is worth. Set flat and percentage damage, defense, block and magic defense per level, per item group. Make +15 a real achievement or flatten the curve for a casual server. Tooltips always show the server's real numbers - the old client even under-reported +15 by half.

8

new skills included

Add-on

Custom Skills

Add brand-new skills in XML. Damage, targeting (single, area, cone, line, buff, heal), stat scaling, debuffs, learn requirements, icon, tooltip and layered visual effects - no client code at all. Eight skills ship ready: Meteor Storm, Soul Seeker, Fire Blow, Blood Storm, Focus Shot, Party Healing, Havok Spear and Wind Soul. MuHelper casts them and they join combos.

Documentation Add to your license →

64

achievements included

Add-on

Achievements

64 achievements across 6 categories out of the box, each with up to 8 tiers. Kills, bosses, PvP, resets, events, chaos mixes, upgrades, rare drops, Market sales, play time - 17 trigger types. Players claim zen, items, buffs, points and currency themselves from a card-grid window with unlock toasts. Add your own with one XML file.

Documentation Add to your license →

9

rank emblems included

Add-on

Rank Badges

Show off rank where everyone looks. Emblems sit left and right of the player's name, over their head and in chat, with a name colour on top. Build ranks from achievement points, VIP tier, level, master level, resets, grand resets, talent points or GM status - mix rules as you like. Badges update live as players earn them. Nine painted ranks, Iron to Legend, ship ready. A natural fit for VIP perks.

3-Tier Progression

Reset System

Regular, grand and master resets, each configurable per account tier with its own level, zen and item costs and scaling rewards. Auto-reset distributes stats for you - as raw points or as percentages of each reset's reward - and the panel shows your allocation live.

Click to expand

24 Quests Included

Custom Quest System

Drop a numbered XML file in and the quest goes live - no code, no client patch. Seven objective types, eight reward types, daily and weekly repeats, prerequisite chains and per-quest level, reset, class and VIP gating. Objectives count live as players play.

3

rates boosted

Player Retention

Catch-Up Rates

Players who fall behind earn boosted EXP, drop and zen until they catch the pack. Newcomers and returning players reach your endgame instead of quitting at the gap. Shown in the buff row so players know it is working.

03 / 07

World & Combat

Monsters that fight back, dungeons that test you, combat that adds up.

80+

monster affixes

New in V2

Monster Affixes

Diablo-style elite monsters come to MU Online. World monsters spawn as Magic, Rare or Champion with up to four affixes - Frozen, Vampiric, Volatile, Wormhole, Pack Leader and over 80 more. Coloured health bars, auras, telegraphed area attacks you can dodge, and loot that matches the danger. Every field becomes a hunt.

15

levels per dungeon

Add-on

Instanced Dungeons

Timed dungeons built on your existing maps, solo or with your party. Each run is private - no one else sees your monsters or your loot. The leader pays once and the whole party goes in together; every member gets their own reward roll. Clear a level in time to unlock the next, across up to 3 tiers of 5 levels, with entry fees, death rules, boss waves and opening hours. A full dungeon browser and live HUD come with it.

Top 5

live contribution ranking

Add-on

Boss Encounters

Turn any monster into a real raid boss. It grows stronger with every extra fighter, tracks each player's damage, healing and tanking, and pays personal rewards by rank - top players, top party, top guild and everyone who took part. No kill stealing. Script phases and special attacks in XML: ground slams with the hit area drawn on the floor, summoned adds, pulls, enrage timers. Field bosses spawn on a timer with server-wide warnings. Boss HP bar and live contribution card included.

4

bonus types per family

Add-on

Bestiary

Every kill counts. Players fill a Bestiary of monster families, and kill milestones unlock permanent bonuses against that family: more damage to it, less damage from it, better loot, or a chance a kill counts twice. Finish every family on a map to master it and earn extra EXP there. Party kills count for everyone. A Bestiary window and milestone toasts are included; you choose the families, milestones and bonuses in one XML file.

Any

monster can be summoned

Add-on

Summon Items

Drop an item on the ground and it calls monsters to fight. Any monster works, vanilla or custom. Each summon item can scale its monster's level, life, damage and EXP and give it its own loot bag, so one monster can become many summons without touching Monster.xml. Set level, map, cooldown and alive limits per item. Great as boss keys, event rewards or cash shop items.

BFS

pathfinding around obstacles

New in V2

Smarter Monsters

Monsters finally find their way around walls instead of freezing in place. They leash home when dragged too far, walk at their real configured speed on every screen, and bosses use every skill they were given. Nightmare, Balgass and the Kanturu bosses fight the way they were meant to.

7

elements, weak or strong

New in V2

PvE Balance Controls

Tune the fight against monsters without touching code. Monster damage per class and per map, how much defense counts, SD that soaks monster hits, and the full kill EXP formula. Monsters can be weak or strong to an element, shown as badges by their HP bar. Optional EXP loss on death - never levels, zen or items. Every default keeps vanilla behaviour.

3

layers: global, map, crowd

New in V2

Respawn Speed Control

Set how fast monsters come back without editing a single monster. One global rate, a rate per map, and crowd scaling: the more players hunting on a map, the faster it respawns, down to a floor you choose. Busy spots stay full at peak hours and quiet maps keep their normal pace. Event maps keep their own timings.

1:1

server and screen position

New in V2

Perfect Position Sync

Everyone sees everyone in the same place. The server now walks players at the exact speed their client draws them - mounts, wings, slows and all - and never throws away a player's newest move. Hits land where they look like they should, and the endless "I was standing right next to him" is over.

7

classes, scaled separately

Zero Client Edits

Server-Authoritative Combat

Every combat formula is computed on the server and pushed to the tooltip. Combo damage scales per class, combos work on multi-hit skills, eight master-tree bonuses that never applied now do, and buff tooltips show the exact value your cast will give.

Click to expand

28 Events

Event Timer & Entry Rules

A live schedule with countdowns for every event, now with tabs, colours and rich tooltips. Blood Castle, Devil Square, Chaos Castle, Illusion Temple and every Kalima tier carry their own level, reset, grand reset and master reset rules - shown on the ticket tooltip before players walk to the NPC. Set daily and weekly entry limits per account for Blood Castle, Devil Square, Chaos Castle, Illusion Temple, Imperial Guardian, Doppelganger and every dungeon, and players see how many runs they have left right on the timer. Eight class arenas - DK vs DK, Elf vs Elf, Survivor and more - are joined straight from the Move window.

50

fights kept per player

New in V2

PvP Kill Log

Know exactly how you died. Every PvP death is recorded with every attacker, damage per skill, crits and the final hits. A death recap pops up when a player kills you, and the Kill Log window keeps your last 50 fights and kills. Covers world PvP, duels, siege, events, Gens and guild wars.

04 / 07

100

rules per character

New in V2

Loot Filter

Up to 100 pick-up or ignore rules per character: by item or group, level, excellent count, sockets, luck, skill, ancient, drop level or "my class only". Saved on the server and shared by the online and offline helper. Ignore always wins.
