BatMUD is one of the oldest still running LPMUDs (it has been online since 14th April 1990), and has an average of over 300 users online (over 450 at peak hours) from all regions of the world.
Despite its age, the MUD is constantly evolving which makes it both challenging and entertaining to new and old players alike. Due to the rich set of features, BatMUD may be a bit overwhelming for a newcomer, but more experienced players often help if asked politely, and registered newbie helpers are available to guide fresh players.
BatMUD features a detailed combat system, player to player commerce, playerbuilt cities, seafaring vessels, mounts and hundreds of custom zones. The unique atmosphere of BatMUD has given birth to many clones, including two sibling sites: BatMUD classic (BatMUD as it was in 1994) and HardCore BatMUD (fast powerplay with permanent deaths). However, the original remains among the largest and most feature-rich MUDs on the Internet.
BatMUD can be played using any normal mud- or telnet application, but it also has its own custom graphical client (batclient).
