So I'm going for the no kills achievement, and I've tried the first mission, the prison about 4 times now being absolutely stealthy and passive as possible. I haven't touched a single person, not even choked them out, I've just gone around them and yet every time I finish the mission it tells me I've killed 1 person. I have absolutely no idea who it could be.
I started the game over from the prologue in case somehow it was an assassin that counted, and I didn't fight them, so there can't be a kill there. I sneak around everyone in the prison, I made sure that the 2 people in the room where I blow up door survive, I don't touch any thugs in the sewers, and yet still 1 hostile killed.
This happen to anyone else?
