This mod is now discontinued, check summary page for details, also check out the new mod I am working for called C&C Generals: Code 13. It includes a lot of new units and structures, and a new faction called "Alpha Zerox". It's great and I'm pretty sure you'll love it! Check it out at their forums, and then look for a moddb page in the near future, lots of people are playing now, don't be left out!
BTW, the Code 13 mod team is currently looking for an unwrapper, we need it desperately and if you wish to help us, email me or PM me about it.
