ismission 6, first half is all walking after you get drogon theres one big fight, just run around and avoid them while the ai kils them, next room get plasma pistol and finish the mision, theres only the chamber fight really to go
chap 6 is also a good place to get chain of death as you get them all bunched up
I personally did it on chapter 11 where you fight all the turrets. It was easy enough to do.
