Okay so I finished the game, completed EVERY mission without killing or alerting anyone, except I thought. Saw coldridge mine I apparntly killed someone didn't know how but I didn't mind re doing it.
So before I redo it I see all my saves are full, cause you can only have 12 or something at a time i think
so i started deleting every save except for my one i did on the final mission.
But now I can't see any of my mission stats, i can't select any mission.
does this mean i have to do the entire game again without killing anyone to get the achievement? I really wanted to play it again but killing everyone in site (and using devouring swarm would of been sweet)
any advice?
