A guy called raptor has made a translator and an oaf files extractor for south the stick of truth.

His dungeon siege 3 extractor was found to work on this game because it uses the same game engine.
So he quickly went to work and came up with these two new tools.
He also has tools for other games like Kingdoms of Amalur: Reckoning and Legend of Grimrock e.t.c
