The Legend of Grimrock Website asks for help from those willing to test the Dungeon Editor and modding capabilities they've been developing for Legend of Grimrock over the past four months. They are kicking off a short public beta of the editor today on Steam, since Steam's automatic update system will aide them in the process, and provide reassurances that the editor will be available for all versions of the game once it's complete. They are also enlisting the support of anyone willing to give feedback on their modding documentation or work on model and animation exporters. Thanks Joao.
