NodeJS based MUD engine with full localization support


  • Full localization for any strings displayed to the player after they log in. This isn't a common feature in MUDs so I'll explain it. Player A and Player B log in, play the same game and see a different language. Same items, npcs, rooms, etc, different language.
  • Scripting support: It's in Javascript! No need for a shitty DSL. The codebase is javascript, the scripting is javascript.
  • Scripting is event-based. Put a listener in the script attached to your mob and it'll automagically happen when the event is emitted. Adding new events is easy as npc.emit('eventName');
  • Pfile saving in JSON, easy to parse for external usage
  • Rooms, items, and npcs are easily described in yaml. No wierd bullshit ~~~~ and byte-specific parsing that requires a GUI editor to build.
  • Arbitrary room exits custom to each room not locked into n/s/e/w and it's not a pain in the ass to add them
  • Did I mention it's in blasting Javascript? No compiling, no C, no cygwin, no 15 year old spaghetti code.
  • Basic leveling system
  • Basic combat sytem. Due to the way the repl works it could be used to do turn-based or real-time combat without changing the base functionality.
  • Basic, easily customizable/overhauled skill system
  • Basic channel system


  • NodeJS >= 0.6.2
