I can't keep the tech priest alive beyond the 3rd wave. Even saving the world skills until the 3rd wave doesn't make a difference. Spamming AOE's and running as fast as I can.
There's a bug that makes it so you can't quit the mission, just have to keep playing it over and over or bring down the program. It feels like this should be easier. And obviously other people have done it.
I don't understand what I'm doing wrong, or if I just have to wait until it's not a green mission any more. Advice appreciated.
