This seemed to help me a little bit. I was getting really irritated with the lack of friendly AI help. I found that when my team would start to go off and do their own thing (secondary objectives) while I was completing the current objective; if you go back to the objective map and click on the objective you are currently doing, then your team will come back to where you are and assist you again. It seemed to help me and I breezed through the last few security campaigns. See if it helps you.
Will try that if I play again.
Ai is ruining my fun to the point of me not wanting to play Brink anymore these last few days. It's that obnoxious to me. And my PSN is
not working, either.

*sigh*
