I played it feverishly over the last couple of weeks.
I reached the storyline point where Deacon meets Sarah. Writing isn't strongest suit of this game, but the encounter didn't make any sense. After the nice build up it was a real anti climax. I did few more missions, but game is turning into a real chore.
Sara had to give up on pursuing Deek because it was eating her consciousness that it was her experiment that led to the outbreak. She wanted to do whatever it took to fix the problem and thus had to let go of her real identity and tag along with that crater lake camp folks. You see her finally finding her way back with Deek and realizing she can do both!
