DuskOnlineRPG (GMUD) open-source, Java
Neat old MUD game that needs to be revived! It's currently in active development by NotZed with his fork called DuskZ. Check out my blog for the links to his work upgrading Dusk. I've created and organized this pixel art for use in Dusk but to also help out Bertram with his game "Valyria Tear" and Roots "Hero of Allacrost".
