The Old Metin2 Project aims at improving and maintaining the 2014 Metin2 game files up to modern standards. The goal is to archive the game as it was in order to preserve it for the future and enable nostalgic players to have a good time.
For-profit usage of this material is certainly illegal without the proper licensing agreements and is hereby discouraged (not legal advice). Even so, the nature of this project is HIGHLY EXPERIMENTAL - bugs are to be expected for now.
