Guide: Exterminator

Phew finally it is done: A guide for all of you, who still have problems unlocking the Exterminator Achievement. A few things beforehand:

 

-I have written the guide while playing through the campaign with a second account, so you can expect the information given below to be confirmed and correct. If I still should have made a mistake counting the enemies, please let me know.

 

-Enemies not listed in the guide cannot or do not have to be killed. This includes all ghosts aswell. Yes, that is right: it does not matter if you shoot the ghosts or let them touch you. During my run I have not killed a single ghost and the achievement unlocked just fine (to put an end to rumors and speculations regarding that topic)

 

-Guide contains minor spoilers. The achievement will most likely unlock when finishing off Alma.

 

Now enough talk... enjoy

 

 

A complete guide to "Exterminator"

 

INTERVAL 01 - INCEPTION

 

POINT OF ORIGIN

 

no enemies

 

 

INTERVAL 02 - INITIATION

 

FIRST ENCOUNTER

 

[ ] After the cutscene of Alma killing your teammates you enter a building. In the room after the dying employee there are 2 Replica

[ ] In the area after the next checkpoint there are 6 Replica in total (inside the building & outside area)

[ ] Enter the next building. In the room next to the one with the paranormal activity and the health booster there are 3 Replica

[ ] 2 more Replica in the next (bigger) room

[ ] 1 Replica upstairs

[ ] When you operate the crane 2 Replica spawn on the other side

[ ] After the next checkpoint 3 Replica will enter the room on ground level

[ ] Finally 6 more Replica in the outside areal

 

Total kills: 25

 

 

INTERVAL 03 - ESCALATION

 

INFILTRATION

 

[ ] Once you reach the first checkpoint and get out of the sewers, enter the building to find 2 Replica

[ ] 2 More in the next room

[ ] Climb up and go through the vent to get behind the fence. In the next room you will encounter 4 Replica

[ ] In the room after the previous one (where you have to climb the ladder) there are 3 Replica to be found

[ ] After the next checkpoint you get back outside and face another 6 Replica

 

Total kills: 17

 

HEAVY RESISTANCE

 

[ ] 1 Replica in the small room to the left once you have climbed out of the hole in the floor

[ ] When they way splits up take the left path. After the checkpoint 2 Replica will run along the catwalk above, 2 will be in the back of the room and another 2 will enter the room shortly after

[ ] You will pass another checkpoint and get back outside where you find 6 Replica

[ ] Still outside go around the corner into the next area to find 6 more Replica

[ ] Once you raised the water level and passed the checkpoint, there will be 4 Replica on the catwalk above (1 patrolling, 2 rush in as soon as you enter the room and 1 after you have passed underneath the catwalk)

[ ] Go into the next room and figh off another 5 Replica

[ ] The next room will have 1 Replica on the catwalk above plus 2 Replica and 1 Heavy busting through the door

[ ] Now comes a tricky part: Go through the door, past the flickering yellow light, around the corner to the left and with activated SlowMo around the corner to the right and shoot the 2 running Replica

[ ] In the next room (the one with the water on the floor) there will be 1 Replica running along the catwalk above

 

Total kills: 35

 

BAD WATER

 

[ ] After all the paranormal activities you will end up in thw room with the victim on the chair and get a checkpoint. After the lights go on 7 Replica will enter the room (5 on the upper level and 2 through the door on ground level)

[ ] Go through the door on ground level and find 1 Replica

[ ] In the next room there are another 6 Replica

[ ] Now the way splits up several times so it's hard to keep track of the exact positions of the enemies. Just make sure that before you leave the large turbine room you have killed a total of 5 Replica

[ ] You will pass a checkpoint and find yourself back in the room with the victim (but now on the upper level) where there are now 4 more Replica

 

Total kills: 23

[ ] In the next room you face another 7 Replica and 1 Heavy

[ ] You will come back outside and have to clear the landing zone for the chopper. In the area there are 8 Relica and 1 Heavy

 

Total Kills: 31

 

INTERVAL 04 - INFILTRATION

 

LZ IS HOT

[ ] Continue forward and you will get outside again. Before you reenter the building you should have killed 7 Replica along the way (their positions depend a little bit on whether they have been alerted or not)

[ ] Inside the building again you will meet 3 Replica in the room with the reflex booster...

[ ] ...and 2 more in the room after the previous one

[ ] Go past the checkpoint and outside again to find the last 4 Replica of this section

 

Total kills: 27

 

WATCHERS

 

[ ] After lots of paranormal activity you will pass a checkpoint and enter a big room. There are 3 assassins on the upper level

[ ] Continue through the building and once you break through the ceiling you will find 2 more assassins

[ ] Once you meet up with Norton Mapes follow the way until you reach a big hall with 4 Replica

[ ] Continue through the door to find 3 more

[ ] Open the security doors and continue on to the server room. On the way there you should come across 6 Replica

[ ] Once you have rebooted the network 4 Replica will enter the room

[ ] Jump down to the lower level. In the next room there will be 4 Replica (1 on the upper level)

[ ] Once you step down the small staircase another 9 ATC guards can be found in the building in front of you (some will come onto the roof and some will stay inside)

[ ] Jump to the roof below to find 2 more ATC guards

[ ] Inside the building again you will come to a vent that you will have to use to pass a gap. On the other side there are the last 2 ATC guards. Important: Kill them before you jump down onto the vent as the vent will break when you try to cross it.

INTERVAL 06 - INTERCEPTION

SAYONARA, SUCKER

 

[ ] Step out of the elevator and kill the 4 Replica

[ ] After you meet Norton Mapes again you will go through a series of smaller labs until you encounter a group of 8 Replica in a big lab

UNAUTHORIZED PERSONNEL

 

[ ] Once you encounter Norton Mapes destroy the turret which he will activate

[ ] As you continue to chase Norton Mapes you come across 6 other turrets

[ ] Continue past the checkpoint and you will meet 4 Replica (2 will jump through the window in the ceiling)

[ ] Go past another checkpoint and kill the 4 Replica

[ ] Now call the elevator and destroy the Mech that comes down with it

[ ] After you passed the room filled with the toxic gas you come to the first turret section. Now this part is a little awkward:

When I ignored the turret and meleed everyone there were exactly 9 enemies in the room and the wooden door remained closed (and Exterminator still unlocked at the end of the game). However when I chose to operate the turret I was able to kill 10 enemies with it and an additional 5 Replica were spawned in the office with the wooden door now being open (those were not the ones from the room ahead!).

(thanks to Dombine for pointing that one out)

[ ] In the next room a body falls down and 5 Replica can be found on the upper level

Great effort. I'll use it if i dont unlock the achievement this time, playing extreme diff.

I'm pretty sure it wont unlock tho, i skiped a turret. Guess they count since a few people mentioned them and you included them in your guide.

 

Following this guide will unlock the achievement, since it's confirmed and counted by you. But on another hand, it has occured to me that it might be a minimum kill limit to get it. Some games are known for giving tricky achievement description. This is just a theory, because of all the rumours of claiming what to kill and what not.

 

EDIT: I can pretty much confirm my theory about a minimum amount of kills to get the achievement. I skiped 1 turret and my achievement unlocked after killing the last pack of monsters before you reach the burning door in Ground Zero. Weird stuff. Anyhow, im pretty happy that i have one less playthrough to worry about.

I also want to thank you for the heads up on the enemies closing gates at Lapdog.

Funny thing is, i didt go for the achievement at all until lapdog.

Wait, the ATC closing the gates in Lapdog do count? Dammit, have to kill them after my Ammo Hog/Explorer/Intel run...

 

Good guide though, I'll definitely use it on my Exterminator quest. =P

Adding without the need of a 2nd post.

Still there might be one or two runners that might not need to be killed (and I'm beginning to support sadfez' theory here) but going through the whole campaign to find out seemed to be... a little bit too in depth ;)

 

It's just that if you follow the guide you will get Exterminator at the end and for the sake of those hard to earn 35 points it sure doesn't hurt to kill one or two enemies more ;)

P.S. I would be very grateful if this could be stickied

P.P.S. It would possibly a good idea to change the links in the achievement guide aswell as in the roadmap. Thank you

 

Agreed. Followed this guide and it worked perfectly during my second walkthrough. Unlocked it along with Real Time, No Juice and Survivalist.

 

I personally wonder why this isn't on the guide, it should.

I'll have to agree with you on this one.. I did not follow any guide, did not care for how many enemies I killed or the ones that supposedly respawn, I simply played through the game normally while taking my time and I got the achievement after killing the last pack of demons in Interval 11.

 

Either it is a minimum limit, or I just got lucky on my first playthrough lol. But if it's a limit, who knows how many enemies you need to kill for it.

Thanks for the guide. It definitely helped me find a few that I wouldn't have using only this walkthrough I'm following.

 

I'm certain I missed at least one enemy, and probably more like 5, but I still got the achievement after killing some spirits in Interval 11 (After you drop down one of the three holes in the floor, a few bust through the wall. Then another pack spawns -- it was that group). I did use the turret that spawns extra enemies and killed most spirits as I was able.

 

So glad it popped or this playthrough might have been almost a total bust. I didn't get Real Time... the one time I used it I reset the game, but I should have just turned off my 360 instead of quitting through the start menu...

Awesome guide! I noticed a few things I thought I'd mention.

 

In Interval 3 - Exeunt Omnes, There's an assassin that runs from you when you drop into the sewers from the grate by the proxy mines.

 

There's another one early in Interval 4 - Watchers, but I can't seem to kill him. Just after you pass through the conference room with the laptop, a body and an assassin come crashing through the windows from the room on the left. He runs into the room to the right and climbs up.

 

Also, 2 of the drones you mentioned during Interval 7 - Flight didn't spawn for me at the part where you "Jump out onto the roof and kill another 2 Drones." I got the achievement though.

Thank you so much for this guide. I just got it and at the last of the ghosts. I let them all run into me without shooting one in the entire game. Anyone who attempts this achievement with this guide, do not do it with the update, I went through twice with the update and it never worked.

INTERVAL 05 - EXTRACTION

 

BLINDSIDE

[ ] Inside the building again you will come to a vent that you will have to use to pass a gap. On the other side there are the last 2 ATC guards. Important: Kill them before you jump down onto the vent as the vent will break when you try to cross it.

 

that's the worst description ever. you don't use the vent, and it doesn't break, you just fall right through it. there's no "trying to cross it" process. have to start this whole achievement over now. thought it was farther on and got like three checkpoints.

The vent breaks after you have crossed it ~1/3. Excuse me if my English has some grammatical errors from time to time but it is not my native language.. I just assumed that the reader knows at least the level layout since this is the only place in the whole game where you fall through a vent.
