I really enjoyed taking over Omni's base; that took some thinking. Heck, just getting there was an adventure in and of itself, as I had to send Andy in alone to clear the path, then bring everyone else up behind.
A couple comments regarding the Free Radical Base, however. The Surveilance Center was within easy reach of my cyclops, and once that was gone, the base was essentially defenseless. I would either put in another Surveilance Center or move the existing one further in. That brings me to my second comment: if you have triggers telling the FR buildings to produce units, they apparently aren't working. The addition of defensive forces would greatly increase the difficulty of taking out that base. (and that would be a good thing

)
Great mission, overall, and I'll play again, if only to take over Omni's base!
