Before starting I recommend taking a look of this achieve

Problem Child
Kill everyone in every level.


Make sure to kill everyone before finishing a level , progress can be checked at any moment at stats > achievements > problem child. every level adds 10% and the achieve should unlock after finishing level 9 (tutorial level also counts)


The boy has toys
Find 1 bobblehead.


Just after exiting the first room you'll see your first collectible , it's a demon statue (there's an achievement for picking up 60 but you can do it with the same over and over again)




Sacrilege

Disable a religious item.

Like in the first Lucius , these will deny your powers/ability to pickup items. throw any item to them to disable.



Electric power!
Kill a person with electricity.


This is easily done at any point of the game , no explanation needed.



Murderer
Kill a person.


She's just looking for attention
Call Marla.


After killing your first victim (cams dude) you'll come across a phone, call to this number 555-0134
Note: you can get a reply of Marla or Ted , keep calling for both achieves.






Is Ted really your friend?
Call Ted.




Back in black
Get Lucius's suit.


Part of the story/unmissable




Bengt!
Pick Up a beachball.

It's located over this shelf behind reception/above Lucius's suit.



Fiery furnace
Kill a person with fire.


Throw a flammable can over this vent. (this room must be open from reception)




Light up the blunt!
Kill a person with a blunt object.


Double Homicide
Make a double kill.


Ronaldo
Kick dead enemy head around.


Go over a body head , easy as pie.




Escape the ward
Complete first level.

I want to ride my tricycle!
Find a tricycle and ride it.


Tricycle is found inside this room , part of the story/unmissable





Smooth elevator
Kill a person by getting them to drop down to the elevator shaft.


I highly recommend attempting this with mindcontrol skill.There's a pair of elevators you can open on this floor (pliers are required) , mindcontrol someone and throw yourself into the elevator hole.



Your lips are venomous
Kill a person with Poison.


For this achievement you need to kill someone with poisoned food , this spot if perfect for this since it has a sandwich machine , pills in next room (combine them) and a dude hanging around.



Nun of that
Complete second level.

Melting pot
Kill a person with Acid.


Your goal at this level will be entering a lab and stealing some info ,go there and pick a bottle of acid over the table



Then go here , use pliers in the sprinkler system at your right and bottle of acid on it



Now back to the lab ,drop your lighter in the room and enjoy the show

A lighter can be found here



Note: It can be also done by just throwing a bottle of acid to any enemy but this way is more fun and cheap if you're going for "problem child"


Acidtrip done
Complete third level.

Like a surgeon
Poison A heart transplant in two ways.


Achievement description isn't actually correct ,however In-game description "Poison a heart transplant" it is

All you have to do is using the nearest bottle of poison on the bloody bag by the heart







Splitting headache
Split a persons head with a circular saw..

Easy as it sounds. use pliers in the circular saw table , wait until he's in position and shot.




Nailed it!
Kill a person with a nailgun


Just by the place where you killed the builder there is a nailgun + 2 nail boxes , pick them up and look for any enemy then kill him.


I'm just a lonely boy
Make someone else shoot you with a nailgun.


Note:Controlpickup passive skill is required for this one

Firstly you will need a charged nailgun or at least with 1 shot left, if you do , drop it and mindcontrol someone. Now that you're controlling him pick the weapon up and shoot Lucius once.




MJ
Touch four kids.


Story related/Unmissable



I just called, to say, I will kill you
Make a succesfull Call.

Story related/Unmissable



Under construction
Complete fourth level.

Butthurt
You need to figure this one out yourself.


This one is fairly easy ,in order to get it you must kill the guy who is taking a shower with a d-ildo.
To gain access the showers you will need the key #5451 (a nurse has it). after getting inside pick the d-ildo up which is here



and go where our objetive is



Put it inside the pressure valve at the right (as shown on the screen) and launch it.


Patience is a virtue
Kill 3 people at once with pressure chamber.


Achievement description is wrong again , you don't have to kill them at once.

Pressure chamber and its control room are on the east wing , you can open it with the help of a flammable bottle , throwing it through the vent.





Mindcontrol is a must have for this. take the control of someone and make your way to the chamber , then fast close the door from outside ( you must be really fast) and turn on the chamber from control room. do this 3 times and the achieve is yours.





Hospitals are for pu-ssies
Finish chapter 1.

Unabomber
Create a homemade bomb from fertilizer.


Don't make the bomb here , just get the ingredients and combine them in the next level.

The combo is fertilizer+gasoline canister , you can find a gasoline canister in Floormart (first store to the right side) and fertilizer at HW shop (second to last at left side)






Rob Bery
Steal money from Ludlow.


Steal money from any cash register.




Cannon fodder
Kill 3 people with firehydrant.


And here we go again , mindcontrol can be very helpful in some achieves and this is one of those. mindcontrol your objetive , stand in front to any firehydrant and break it ( you can use any item to do it , personally beachball is my favorite)




Smoking kills
Kill 3 people with the help of cigarettes.


Thanks Twisted-Spectre for discovering it

In the bar at the left side of the road, there's a guy with a description eluding to him being a smoker, give him some cigarettes and wait till he ends talking with the barman.



He will go into the alley next to the bar and stand under a ladder (you can also find cigarettes here) throw something at the ladder lock and it will come down crushing him. reload your save and repeat this 2 more times to unlock the achievement.





Out of gas
Explode a gas pump.


There are two ways to do this FlameOn skill or a lighter , regardless of your choose you'll need a pliers , cut the mecanism and make it bom.



Sleepy hollow
Kill everyone at Ludlow.


This will come naturally if you're going for "Problem Child"


Ludlow is too small for me
Complete sixth level.

Roadkill
Witness a person getting ran over by a car.


Mindcontrol is the easiest way to do this. take over someone and go to the high road near the start , wait in the mid until a car comes and throw yourself to the road (must be very close or it stops)




Hit, run and beat it!
Get run over by MJ.


Not sure what MJ means but it's a blue van that ocasionally comes from any side, just kill yourself with it.




Hit & run!
Get run over by a car.


Trumpets filled with water
Complete seventh level.

Grinder
Use a woodchipper to make minced meat.


This can be annoying as it requires Push skill (tier 4 object control)

Easy to do though, turn on the woodchipper and wait until anyone stands in front of it then push him





Sledge-hammer-time!
Hit a person with sledgehammer.


Sledgehammer is at the roof of power plant near the woodchipper. (Thanks LFox)
Pull is your best bet for this achieve ,just stand in front of this guy like in the screen below and pull the hammer.(might take a few tries)



Put your lights off
Complete eight level.

Sting
Use bees to kill an enemy.


Near the end when you enter Locust Farm , you'll come across to some kind of tents with a sign ,in of those there's a text like this "Pheromones connection to bee aggression" enter here.

Inside there's a scientist and 2 levers , use them both and bees will be liberated killing him.






Corn king killed
Complete ninth level.


Problem Child
Kill everyone in every level.


I got this achievement here , even though it says every level (there are 10)

I remember when I lost my mind
Use chainsaw to kill an enemy.


Pretty straightforward , chainsaw location is here (as any heavy weapon you can't pick it up with Lucius , mindcontrol is your only way)



Ludlow Chainsaw Massacre
Use chainsaw to kill an enemy in the final episode.


Don't fear the reaper
Kill 3 persons with a scythe.


Same as chainsaw, use mindcontrol



Finally it's done
Complete the game.

Ted Bundy
Kill more than three persons in a row.


If you haven't gotten this , here's a nice spot to do it
