L2J is an Open Source, Alternative Lineage 2 Game Server written in pure Java for best compatibility.

L2J gives you the possibility to legally host a game server for this popular Korean MMO created by NCSoft.

Project’s first release we know of were made in June 27, 2004 by L2Chef. Lots of people have passed for the project, much of its code evolved and much more is left to do yet. But the project goals stood consistent during these years.
