I've spent about an hour trying to get past the bit where you see the Ceph ship crashing and Gould wants you to go get some examples of them.
I've killed just about every guy I've come across except for the last two. Almost twenty guys I think.
My problem is one of the last two guys, while running perpendicular to the direction I was going, one of them said, 'You know what player, **** you and your cloak. I'm shooting you in the head and you can restart the entire bit again.'
Fair enough if I blunder something and get killed for it. Not fair enough when I the AI decides to forget it can't see me or that it's had enough of me killing it's dudes and murder me so hard I loose a tooth.
