All i did was adding the names of the locked challenges in another category of challenges. The first category is "Meet the Council" now named "Tutorial & Meet the Council", this one has the tutorial and the original Council challenges plus a extra named puzzleX i found in the game files. The last challenge category "Meet the Shaolin" is now named "Meet the Shaolin & Super Challenge Pack" and now also contains the previously un-accessable Super Challenge Pack.

Notice! This zip folder also contains the original and modified versions of steam dll's, this is only in the interest of video game preservation. If steam is uncomfortable with this then i gladly remove them and re-release this without them.

Unzip the zip folder in to your hero academy install folder and run it from steam launcher.
When the game gives you a pop up about not connecting to servers just press the x button on the pop up (not the game window).
