Can anyone give me some details on how the tech tree works? I want to try to fix my carrier situation with additional units and techs. I'd like to know how to add units (if possible) and where all I need to make changes so things work. Ideally, I would like a 5000-word essay on how to change tech trees
, but just a few kicks in the right direction would be helpful.
Thanx in advance
