Here is the source code for RA3, as of Patch 1.04 - The last patch. You're welcome to use parts of the RA3: Undecided source in your mod, just add credits to our mod please!
We've came to the conclusion that we are no longer interested in this mod. It has been a long road to this and on this long road we've had lots of fun but it is time to turn off.
(Though I am still interested in RA3 modding so I am starting on another mod. This mod will focus more on balance & completely changing gameplay rather than adding new things. Though I may decide to add some of the units from this mod to it.)
