THE GATEWAY TO ECLIPSEMU
Your next adventure starts here.
Create an account, install the native client, then enter the realm. Choose your platform below; the Windows setup is a small online installer, not a 2.3 GB download.

HOW IT WORKS
Small download.
Entire world.
The Windows setup downloads two checksum-verified, compressed archives from the upstream MuMain release, then extracts the matching runtime and game data. The archives total around 856 MB; the installed game uses roughly 2.3 GB. Verified archives may be reused from your local cache on later installs.
Already have a complete client? Choose that folder in setup to repair EclipseMU branding without downloading the game again. For a fresh install, choose an empty folder.
The installer is unsigned. Browser or Windows security prompts may still appear; HTTPS protects the website connection but does not make the installer a verified publisher.
BEFORE YOU ENTER
- Create your account
Register on the website ↗ before starting the game.
- Install the client
Windows: run EclipseMU-Setup.exe as your normal user; Direct3D 12 graphics are required. Linux: run the native Ubuntu 26.04 installer as your normal user; a Vulkan-capable GPU is required.
- Choose your channel
Server 1 is PvP; Servers 2 and 3 are non-PvP. The client is configured to connect to the game at 192.168.2.28:44406, so playing requires LAN access or an approved VPN path. Publishing this website does not expose the game server.
SAFETY FIRST
Check what you download.
Compare the SHA-256 beside each download with the file you received. The installer verifies its upstream archives automatically. Do not turn off antivirus or SmartScreen to install.

MuMain runtime and matching game assets are obtained from their upstream source during installation; the small setup does not bundle the game. Use game assets only where you have the right to do so.
