I was assigned to kill an NSF leader on a plane in LaGuardia National Airport, but Paul has been urging me to side with the NSF. My murderous nano-aug superior is insisting that if I don't kill the guy, SHE will do so. It felt like a serious breaking point with major plot ramifications.
On my first attempt, I died horribly.
On my second attempt, I was able to kill Anna Navarre, and the NSF leader actually survived! I'd gone so far as to booby trap the plane with land mines, though, and I inadvertently set one off before I could talk to the guy.
On all my subsequent attempts, Anna either killed the guy before I can kill her, or she wound up killing me herself. I finally gave up and just resumed playing from a file where both of them died in the altercation.
Does the NSF leader have anything more to tell you if you save him from Anna? Does Gunther wind up killing him? What would have happened if I'd followed my superiors' orders and either killed him outright or let Anna kill him?
