Who we are
About OpenMU
A MU Online server built to last: modern technology, clear rules and your data protected.
The game
- β’Full MU Online Season 6: 7 classes, maps, events (Blood Castle, Devil Square, Chaos Castle), reset and ranking.
- β’Server based on OpenMU, an open-source project actively developed and maintained by the community.
- β’Client that runs right in the browser (WebGL 2): no download, works on Windows, Mac and Linux.
Security
- β’Everything encrypted (HTTPS and WSS): site, game and the server connection.
- β’The game server and the database are not exposed to the internet: players only reach them through a secure, controlled bridge.
- β’The server verifies player actions on its own side (such as range and attack speed) instead of trusting what the client sends.
- β’Passwords stored encrypted (bcrypt). Payments through Mercado Pago: we neither receive nor store card data.
Your data, protected
- β’Automatic daily backup of the game and accounts, with 14 days kept on the server.
- β’A daily copy kept off the server (30 days), in case of a serious failure of the main server.
- β’Tested restore: the backup is validated when it is generated and recovery has been tested end to end.
Transparency
- β’Public status and uptime, measured automatically every 5 minutes, without hiding outages.
- β’Clear, written rules: terms of use, refund policy and VIP rules published on the site.
- β’Every update is first tested on a separate test server before going to the official server.
The server status, uptime and last backup are open to everyone.
