UchuServer

About

Lego Universe was a massively multiplayer online game developed by NetDevil and published by Warner Bros. Interactive Entertainment, running from October 2010 until its shutdown in January 2012 due to unsatisfactory revenue. UchuServer (Uchu) is a from-scratch, C#-written server implementation for the shut-down 2010 MMO Lego Universe, reimplementing core systems such as missions and achievements, quickbuilds, rocket building and launchpads, vendors, items and skills, factions, and four playable minigames (Avant Gardens Survival, Footraces, Monument Race, and Combat Challenge) with leaderboards. It supports Python scripting for custom minigames and additions, plus a REST API, and is designed to run alongside an original, unpacked game client patched with a community networking mod.

Getting started

Playing requires an unpacked copy of the original Lego Universe client — patched with a small community networking mod that replaces the outdated original protocol, and run via Wine on Linux/macOS — alongside the Uchu server, which can be run from a prebuilt release tool or built from source with .NET. After the first launch generates a configuration file pointing to the client's resource folder, an account is created with an in-game or console command before you can log in and play.
