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 noticed my motivation for Betamod was dropping recently, so I decided to add a bunch of content before my motivation fizzled out completely. These changes include: Maps, Props, Buildings, and units. There are too many to list, but i'm sure map makers will be very happy! The Installation has been changed too, If you made a directory for BetaMod, scrap it; Make a new one. Extract all files to it, and have fun! also, if you downloaded the 0.2 shellmap, delete it, the 0.3 version is in this download and i assure you is WAY BETTER!
To install: create a backup of your zerohour directory then proceed to extract files into said directory.
C:/Program Files/EA Games/Command & Conquer Generals Zero Hour (rename new directory) C:/.../Command & Conquer Generals BetaMod
