1. The ammo box
The bowels. The breadbasket.
Turrets don't have infinite ammunition. They've got exactly two full bursts worth of ammo on rank 2/5 (increasing with each rank with some element of randomness thrown in), about 10 bullets each, and this big brown box is where they store it. If you shoot it before they've had a chance to fire, they will be completely unable to retaliate.

Do note that whenever they detect you, they will
automatically chamber a round before firing. As a result,
if you're ever in a situation where a turret stands down after
you got detected and you decide to cut off its ammo
supply, remember that it still has a round ready to go
regardless of whether or not the box has been destroyed.

It should be pointed out that this component is in a
very disadvantageous position for the turret, and that
shooting the ammo box is very likely to topple the turret
over, making it extra difficult for them to retaliate in any way.

2. The motion sensor
Fry it, and when the turret detects you, there will be a few seconds delay before it zeroes in on you and starts shooting at you. It will also widen your window of opportunity when you're hacking them. There are better things to shoot at. Fun in a shoot-an-apple-on-top-of-someone's-head way.

3. The gun
It's a big target, it's enticing to shoot at, but don't even bother, that thing's a trap. It's extremely strong and you won't penetrate it, not even with a Desert Eagle at point blank range.

4. The camera
The peeper. The globe. High priority. Without it, the turret will have no way of shooting back, and you will be able to easily hack and destroy it as it takes away its chances to detect your hacking. If you get spotted, either quickly shoot at the center of the light, get to cover, or if you're close enough, sprint and get behind it.

5. The barrel
Your highest priority. Shooting it will bend it sideways. Even if it detects you, all it will be able to do is shoot at the wall besides you, maybe break a window if it's lucky. Be sure to stare directly into its terrified cyclopean eye as it desperately tries to fend for its life. In vain.



6. The main cable
Go for the jugular. Severing it will cut the upper part of the turret from its power supply, effectively destroying it in the process. A hard thing to do, but one of the better ways to style on them.

7. The battery
The heart of the turret. The power supply. The game tells you to aim for it, but most of the time it will be concealed by objects or behind walls, and the upper part of the turret will be easier to see and to shoot 90% of the time. If you somehow catch it with its butt hanging out in the breeze and peeking out of a corner, and you're feeling especially merciful today, by all means, go for it. Attack it at a 90° angle if possible, otherwise there's a probability that your shot will ricochet on the casing for normal turrets.

8. The motor
The spinal cord. Shooting it will result in quadriplegia for the turret, rendering it unable to rotate its upper part. A good way to save ammo if you intended to shoot at something else but you hit this component, and it's not looking anywhere you might want to go. I won't judge, promise.

9. The legs
Shoot at them repeatedly to bend them out of shape and topple the turret. If you've got the ammo, a little target practice never hurt anyone. Make a pretzel out of them.
Edit: Another way to do it is to shoot the upper, thin part of the leg; doing so will rip the leg off entirely. Tested. Thanks to pepod3 for this find.

Do note that some turrets will appear to be in a dormant state. Walking in front of them or failing to hack them will activate them; however the activation period is extremely permissive and will leave you ample time to find cover, a hiding spot, or if you want to make Daddy proud, to get behind them and get to work.

Kinda looks like one of those old Ostwind tanks. These start appearing at Rank 4 and are tough nuts to crack, unless one of them decides to expose its derriere like this one right here. They've got very thick, angled sheets of metal protecting the front and the sides of the base and the upper part; don't even think about trying to shoot through that. Not even up close, at an angle of 90°.

Frontally, their only weak parts are the motion sensor sticking out on top, the legs, and the barrel. Even the top of the legs are covered by armor, therefore you won't be able to cheese it easily by blowing one of its legs off. It's still possible to bend them, though, and the top of its hind legs isn't armored. Go nuts, junior.

Big.


Annoying.


Likes to hang out with its buddies.


Swat them out of the air and make me proud.


1. The camera
Same as its grounded cousins. Take it out and they'll be doomed to a fate of wandering aimlessly in the sky until you complete the level.

2. The shielded rotors
Clip their wings. They normally have two, this is just what they look like when you're done with them. If you take one out, they'll still be able to fly, but they'll be much clumsier and it'll be harder for them to come after you. They're likely to ram into walls too, which damages them immensely, so try and run around corners if you can. It also means they don't steer quite as well; if your target comes
after you with one of its rotors out, you'll be able to
sidestep them easily and resume firing.

3. The motion sensor
As far as I can tell, same deal as the turrets. Haven't been able to take this component out without destroying the entire bot altogether yet.

4. The taser
The dart. The proboscis. Destroying this component will, of course, mean that this oversized Asian hornet will not be able to retaliate, but chances are that if you did this, it's on the ground already. Still, be careful when it's downed, and don't walk in front of its taser. It can still electrocute you up to approximately two meters away.

Addendum : Concerning these vermins, if one of them is coming at you and you want to disable it in a quick and efficient manner, train yourself to aim center mass, in this case meaning the long, teal block. It's extremely fragile and there's a good chance that you will either break the battery that is housed right above the camera, or shatter the rod that connects the two rotors together.
Thanks to Reaper.

The security cameras in this game act like any old security cam in any other game. Stay too long in its area of detection, and it will raise the alarm, making every nearby turret and drone aware of you. Remedy to this by either destroying it or staying out of the light for a few seconds, and any alerted enemy killdrone that doesn't have a line of sight on you will stand down and/or resume patrolling.

1. The camera
Destroy this, and you'll disable the bot. Sometimes it kills it as well, sometimes not, the result is effectively the same : it won't be able to call for help.

2. The arm
This is the fun part. Shooting it will break the camera's support, making it dangle helplessly in the wind. Still, there are other enemies that are more fun to toy with than this one.

3. The main cable
Put it out of its misery, you monster. Why don't you write a guide about it, you like to play with your food so much.

That's a lot of negative space and a big picture for a bot that's relatively easy to understand and deal with, maybe I should've expected that. Have a Risotto recipe instead.

6 cups chicken broth, divided
3 tablespoons olive oil, divided
1 pound portobello mushrooms, thinly sliced
1 pound white mushrooms, thinly sliced
2 shallots, diced
1 1/2 cups Arborio rice
1/2 cup dry white wine
sea salt to taste
freshly ground black pepper to taste
3 tablespoons finely chopped chives
tablespoons butter
1/3 cup freshly grated Parmesan cheese

In a saucepan, warm the broth over low heat.
Warm 2 tablespoons olive oil in a large saucepan over medium-high heat. Stir in the mushrooms, and cook until soft, about 3 minutes. Remove mushrooms and their liquid, and set aside.
Add 1 tablespoon olive oil to skillet, and stir in the shallots. Cook 1 minute. Add rice, stirring to coat with oil, about 2 minutes. When the rice has taken on a pale, golden color, pour in wine, stirring constantly until the wine is fully absorbed. Add 1/2 cup broth to the rice, and stir until the broth is absorbed. Continue adding broth 1/2 cup at a time, stirring continuously, until the liquid is absorbed and the rice is al dente, about 15 to 20 minutes.
Remove from heat, and stir in mushrooms with their liquid, butter, chives, and parmesan. Season with salt and pepper to taste.

Not much to tell. These turrets are identical in every way to their land-dwelling cousins, except that they appear to have a lower rate of fire (which may imply a higher penetrative power by typical videogame convention, be careful if you're taking cover behind anything that isn't made of brick, thick concrete or metal), their main cable doesn't actually connect to anything (but the turret will still go down if you sever it), and you're more likely to hear one of those heart-stopping beeps if you enter a room with tall ceilings and you didn't slice the pie properly.

The main components are still highlighted, save for the gun, which is still the impenetrable big green bullet trap behind the barrel. Cross compare them with those of the ground turrets.


Another thing that you should be prepared for is that the game has room to spawn a ground turret below a ceiling turret. Watch out for this kind of trickery in cramped construction-type modules, as you might think you're only hearing one turret rotate, only to promptly get your face or legs pumped full of lead once you try to peek from your cover in order to investigate the source of the noise.











Oh. Oooh. Oh no.
Now this is just plain nasty. Just one of these in combination with a security camera or an armored turret is enough reason to leave the room and go tape hunting somewhere else without getting mocked by your fellow Receivers. It's got the same thick sheets of metal as the armored turret, only it won't expose its vulnerable backside quite as often. It doesn't have legs to knock over. It often spawns in a tight corner, on a high ceiling. Frontally, its only exploitable weakness is its motion sensor. Most of the time, your only option here will be to blindside it and go for its more juicier sides.





And even then, just look at that. Even the camera is completely concealed. Again, don't try to shoot through its armor, it won't work.
Remember that this big, mean piece of ceiling junk also takes advantage of the increased ammo all turrets get when you go up a rank. Combined with the armor, the increased enemy density and the nastier enemy types appearing alongside the armored ceiling turrets, trying to waste their ammo is incredibly inefficient at this point in the game.



Bending its barrel and hacking it while you're in full view will likely be your greatest triumph in the game.

Savor it.
Make it last.
Remind it who the prey is.

Many of these drones were bullied in the process of making this guide. Thank you for reading. Have fun and remember that Glock rhymes with "slide the lock".
