Monsters move according to their walking animation speed, while offline-levelling and bot characters move according to the speed provided by their wings, mounts and buffs. Chasing monsters can also navigate around walls and other obstacles while maintaining pursuit. We invite everyone to explore the new content and experience the extensive character, combat and gameplay changes introduced with Season 22 Part 1-1. Test Versions The test version is available only for Customers who upgraded their SeasonPass to level 13. All test versions are limited in time and will be shut down after the launch of the official release. Limiting the test version to actual holders of the required SeasonPass helps prevent Customers without the required pass from running early test versions on live servers, which previously had a negative impact on the MU market and its community. SeasonPass The SeasonPass 7-12 levels are currently available at a reduced price of up to 35% off. The promotion is available until 20.10.2026. To purchase or upgrade your SeasonPass, go to License Manager and select Manage SeasonPass.

Custom Maps & Monsters: Build Your Own Worlds and Bosses in Pure Lua A new plugin for the LuaAPI ecosystem. New playable worlds and monsters from your own models, scripted entirely in Lua. Adding a world or a monster of your own to MU used to mean the same thing every time: a client developer, map limits hardcoded in the binary, and a fresh build for every model and every effect. Custom Maps & Monsters takes that wall down. Register a world, put your own models on monsters and NPCs, and give both a Lua script that runs every frame. No client patching, no rebuild. What it is Custom Maps & Monsters adds two things the client was never built for: playable worlds above the original map range, and monsters drawn from your own models. Both are configured from encrypted files, and both can be scripted in Lua. The plugin is what brings a world into the game - it does not draw one. Worlds are made and edited in MU World Creator, which is also the only way to generate a mini-map for them. Worlds the client never shipped with Register a map and it behaves like any other: warps, gates, spawns, its own music. From there a per-frame Lua script owns everything you see. Scenery animation: scrolling water, breathing lava, smoke vents, anything you can drive per frame Weather: written in Lua, from drifting snow to storms with lightning Distance fog: per map, with the sky behind the terrain matched to it Object culling: scenery past the fog is skipped, and fades out instead of popping Fading roofs: buildings open over the player, from a table or from a script Ambient sound and birds: placed slots and flocks, driven from the same script Fog and culling work on the original maps too, not only on new ones. Monsters from your own models Your own .bmd models on monsters and NPCs: scaled, tinted and lit A second render pass: glows, beams and crystals drawn over the body Attack effects: your own, or borrowed from any monster the client already has Player skills on monsters: the client draws its half, your script adds the rest Per monster: weapon slot, move speed, sound actions and render flags Built for fast iteration While the server grants dev mode to your account, the same folders load plain .lua and a console shows script errors as you work. The API is identical either way, so you develop in .lua and ship .gsc. Scripts and terrain are packed with your own 32-character key, so players load your work but can never read, copy or edit it. See it working The plugin ships with a finished map and boss you can put on your server as they are: the town of Lost Land of Tarkan and the Pharaoh boss. Beside them sit two reference builds, there to be read and copied from: Tarkan Copy, world 160 — a copied world, registered, with its scenery and weather scripted Hydra, monster 2498 — a custom model with a second render pass, lights and attack effects Every page of the documentation builds on those two rather than inventing a new toy, and both can be deleted without breaking anything else. One tool in the box IGC File Encrypt — packs terrain, scripts and config files for a live client, and renumbers a copied world in one pass Where to buy? The Custom Maps & Monsters plugin can be purchased from our store. Availability and documentation Full step-by-step documentation - from registering your first world to monster skills and the wire format — is on the wiki. Screenshots
