Get your evil twin on! This is the upcoming expansion to the Order of the Stick Adventure Game: The Dungeon of Dorukan, featuring fully playable versions of villainous Nale, Sabine, Thog, and the rest.
This will be a stand-alone expansion to the The Dungeon of Dorukan and will not require the base game to play. The expansion can be combined with the base game for even more gameplay options!
Rich Burlew basically announced that he had an illness that limited his health to the point that he had to devote all of his time to the comic (and the collection of said comics into books.) As he does the art for the game (and created the Order of the Stick world) and didn't have the time to devote to it, this expansion was put in limbo.
