View Full Version : Research PhD Achievement question

I have gotten all of the research achievements except for this one. I have fully researched security cameras and turrets to the max as well. Can someone point out what I am missing to get the PhD achievement? Thanks!

Just after I posted I realized I don't quite have all of the research on the flying robots. Sorry!
