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!
I managed to get a fully functioning laser paladin into the game, however, it is currently only available in the World Builder.
This is another unit I have fun with.
