The Age of Wonders III forums announce open beta testing is underway on Steam for modification tools for Age of Wonders III, regretfully noting these are for Windows only, though OS X and Linux users will be able to use the mods they create (thanks Dan). Triumph Studios also says the upcoming version 1.7 update for their turn-based strategy sequel should leave beta for full release this month, but are not clear on whether these new mod tools will be released at that time. They have instructions on how to participate in the beta as well as how to revert to the prior version to preserve existing multiplayer compatibility.
