Destroy 10 turrets.
You do NOT need to get this in a single playthrough. After you have finished your first playthrough and still don't have the achievement, load up the chapter "Arrived at Fontaine's station" and play through again destroy turrets until you have the achievement. For some reason the game counts turrets you have destroyed regardless of whether you destroyed the same one a bunch of times.
Credit to spxyu02 and X509Cert for directions to the turrets after loading the chapter "Arrived at Fontaine's station"
spxyu02 - "I was on 8/10 after my first playthrough (killed some while possessed I guess), loaded said Chapter, and knocked out the first one, grabbed a lock-pick in the crouch-accessible area across from the first turret, opened the locked door on the first floor, and the next turret is at the bottom of a spiral staircase being worked on by a couple splicers"
X509Cert - "Following on from Spxyu02 - _ finished 7/10, take out the first two turrets he mentions, then follow the arrows (press up on D-Pad) you'll come to some stairs and some splicers - take 'em out and you'll see another turret. "
