MUME IX is the ninth major version of MUME, launched in 2022. It represents the largest single expansion of the game world since MUME VIII, adding approximately 1,500+ new rooms and substantially reworking the starting region.
Major changes
Bree-land rebuild
The entire Bree-land starting area was rebuilt from scratch with new rooms, revised connections, and updated mobile populations. This was one of the most significant zone rebuilds in the game's history, affecting the experience of every new character.
New areas
Ten new areas were added, expanding playable territory across Eriador and beyond. The total world size grew to approximately 28,000 rooms — a 40% increase since MUME VIII launched in 2002.
Expanded subraces
The subrace system introduced in MUME VII was expanded with new options, giving players more customisation when creating characters.
Other improvements
MUME IX also added modern protocol support including TLS-encrypted connections, UTF-8, XML output mode for mapper integration, and GMCP/MCCP2/MNES/MSSP telnet extensions — making the game compatible with a wider range of modern clients.
