A collection of 676 SC2 icons, made by me, recoloring a bunch of sc2 icons including some of the mutator icons that I resized and cropped, in order to make them usable as ability icons. Most of the icons are icons displaying energy effects and are mostly recolored icons of Starcraft 2 and a couple of original icons, if you use them in your project yo can credit me if you want to, but there's no problem if you don't, also feel free to reupload them anywhere you want.
The zip file, contains two folders, one with the icons in PNG format so it's easy to view them and identify what name belongs to what image, and another with the icons in DDS format that contains the icons that you import into Starcraft 2.
