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.
