BioShock 2 Remastered

Even though the achievement says hacked security, I was able to get this using the automatic turret thats deployed by the remote hack tool. By far the easiest way is to stock up on these and use them when gathering ADAM with the little sisters. Much easier than luring enemies to hacked turrets and cameras.

Another trick is to let a camera see you, than hack the bots it sens at you. Once you have 2-3 bots their barrage should also net you some kills, especially while gathering.

Description is somewhat misleading. Get 50 kills with turrets, including turrets summoned by hacked cameras, is more accurate. The kill count includes flying sentrys gifted to you and the mini-turrets you can drop with the hack tool.

Obviously, hack everything. Try to always have two hacked sentries with you. The Repairman tonic will let you heal them and increase their damage, so equip that when Eleanor gives it to you. If you use the mini-turrets frequently, you'll have no trouble getting this by the end of the game.

If you should reach the end of the game without this achievement, it can be farmed. Find a hackable object; safes are best, but anything indestructible will work. Stop the needle in the red to trigger an alarm. Shock and quickly hack two sentries, going for a blue damage bonus. Let those two handle the next sentries. Repeat, replacing the sentries as needed. This'll take a while, but it'll work.

You can unlock this in the protector trials very easily. Choose a level that starts you with either hack tool mini-turrets or the Security summoning power. Sit at your little sister and let them get the kills.

Another very easy way. Find good spot with turret and 3-5 enemy. Save game. Hack turret, wait until enemy die, reload game. Repet :)

If you still haven't unlocked this before the last level of the game, there is a spot that you can use to boost this achievement. You'll need the "Security Command 2" plasmid, although "Security Command 3" makes this much easier. During the sequence when you are chasing the Alpha Series Big Daddy You'll come into a cafeteria with a security camera and an audio log on a table. Summon two security bots by holding with the plasmid equipped, then purposely be detected by the camera and hide in the back corner of the room. Security bots will fly in to the room and your friendly bots will attack them. When the security alert ends, just get detected by the camera again and repeat until the achievement unlocks.
