Well the patch is almost done in terms of new units howewer there is a plan to introduce some new units one for China probably Chinese version of Grumble. Navy units for Russia, China, and USA. Thats all i can think of now but this site will be updated also so check it if you want.
In missions i have big plans make AI really problematic wont say smart cause that is not possible for AI to be smart you need to have game that is using four cores for AI to think. Than AI think in real time just like you and can be as good as any human if not better. But my plan is to make AI build support units to artillery and aircrafts so that it supports them. And eventually if you let it it will buld new factories close to your base and it will owervelm you if you let it offcourse. I will write more about this in the future.
