BetaMod is designed to add units and abilities locked away inside of the Zero Hour files and to include new ones for a more interesting gameplay experience without taking anything away that makes Hero Hour what it is. If you want to add any media, that's fine by me, just make sure it's appropriate!
A long while ago, I made a map called New Twilight Flame. It was a remake of the Buggy ZH map of the same name. After a while I decided to remake it using the Generals1 version of The map. This map contains aspects from both maps, and a few other new features. ONLY COMPATIBLE WITH VERSION 0.3
