The official subverse for all things Meridian 59.
Meridian 59 is an MMO created in 1994 by Archetype Interactive and released in 1996 by 3DO. 3DO shut down the servers in 2000 and sold the game to Near Death Studios, who opened two servers (101 and 102) in 2002 and eventually returned the game to the original creators in 2010. The game was open sourced in 2012 and there are now three actively developed servers, server 105 in the US and servers 112 and 200 in Germany.

The three servers are all based on the 105 codebase, and the code is available on GitHub. The same development team works on all three servers, and is always looking for new contributors.
There is a guide to getting started with Meridian 59 development here. We also have an IRC channel on EsperNet, #Meridian59de.
