Interested in furthering the development of Classic Ultima Online or the RUM Construction Kit library and editor used to make it? Maybe you’re just interested in building and hosting your own online client and server for CUO? Or, perhaps you’re interested in creating your own online rogue-like, Ultima clone, or MUD using RUM?
Both RUM and CUO are now available as open source Mercurial projects on Bitbucket!
Please visit the project page https://bitbucket.org/rumteam/openrum to obtain the project source code and to learn more.
