If this guide is of any use, please rate it. It means a lot to me.

If you need some help with the walkthrough or read some of the (possible) story, check my other guide:

• Containment unit no. 1 is in the Hazardous Waste Landfill, after the second hive and towards the exit.
  
  
• Get rid of the two guards with automatic rifle in the hallway, enter the door and smash the unit, after devouring the two scientist.
  
  
• This ''DNA'' will unlock the ''Echolocation'' ability that will allow you to ''locate edible corpses''.

• Containment unit no. 2 is in the Frontier region and you can find it towards the entrance of BSL-4 Research Ward.
  
  
• You must have ''Xiphorrhea'' ability that allows you to break through wooden barricades.
  
  
• Smash the wooden barricade next to the entrance by the fan and enter the room.
  
  
• In the room, you will find the containment unit which gives you DNA with the ''Polycheiria'' passive ''grow a second prehensile tentacle''.

• Containment unit no. 3 is in the Uranium Mines after the first hive.
  
  
• You must already have these abilities absorbed: “Xiphorrhea”, “Photokinesis” and “Hydrophilia”.
  
  
• Use ''Xiphorrhea'' to smash the wooden barrier and go down in the room by using ''Hydrophilia''.
  
  
• Once inside drop all your biomass in the red water pool in order to get ''Photokinesis'' - the ability to become invisible.
  
  
• Flip the lever on the left to open the door and activate the lasers.
  
  
• Make sure you are fully charged by pulling the electric switch above and be sure such electric switch is fully charged also, then use “Photokinesis” to avoid the lasers - keep using it - and cast your cobweb to recharge your energy level in order to get past the lasers.
  P.S. This ability does not consume energy, if you stay put - so stop at every grid, take your time and shoot your cobweb at the electric panel, always pressing the ''Photokinesis'' ability button nevertheless.
  
  
• Absorbing this DNA will give you “Electrosis” ability that is ''maximum energy level increased''.

• Containment unit no. 4 is in the Botanical Gardens.
  
  
• You must already have ''Parasitism''.
  
  
• You will find an automated rifle guard patrolling a room behind a door on the left of the hive.
  
  
• Reach the guard using the ''Parasitism'' ability through the water at the bottom left.
  
  
• Use the guard to open the door.
  
  
• Switch back to the amorphous being and enter to the left.
  
  
• Enter the door and flip the lever - right door will open while left door will close.
  
  
• Get the same previous guard to the bottom between the two doors.
  
  
• Enter the doors and flip the lever again - right door will close and left one will open, but the dead guard is inside.
  
  
• Use ''Parasitism'' to get control of the guard once again and climb the stair until the top, switch the lever - now both doors blocking the entrance to the containment unit will open.
  
  
• Absorb the DNA ''Pyrophilia'' passive that gives you ''fire resistance increased''.

• Containment unit no. 5 is in the Leviathan Reef Base - not the Bridge.
  
  
• You must already have the following abilities: ''Hydrophilia'', ''Harpagorrhea'' and ''Keratosis''.
  
  
• Use the ''Harpagorrhea'' to unblock the pipe to the right.
  
  
• Swim through the tube with energy fully charged and resist the first explosive using ''Keratosis''.
  
  
• Recharge your energy using the switch on the top left, then flip the lever on the top right - doing so will close the right door and open the left door close to the electric switch.
  
  
• Now go through the second explosives using ''Keratosis'' again.
  
  
• Fully recharge your energy at the electric switch at the top and go past the third and last explosive.
  
  
• Containment unit no. 5 you will award you with the ''Pyrophilia'' passive that increases fire resistance.

• Containment unit no. 6 is at the exit of the Relith Science HQ to the right.
  
  
• You must already have ''Photokinesis'' and ''Harpagorrhea'' ability - the latter is to pull the blockage in the passage to the containment unit.
  
  
• Deposit your biomass outside, once or twice, you need to use ''Photokinesis'' to become invisible.
  
  
• Enter and go through the door, flip the lever to make the laser appear and open the door below.
  
  
• Go past the laser with ''Photokinesis'' and flip the lever on the left in order to open the gate above the red water pool.
  
  
• Go back from the bottom left where you deposited your biomass and absorb it - then release this very biomass in the red water pool where you opened the gate.
  
  
• Use ''Photokinesis'' to get past the laser, flip the lever below the laser again - the door above the pool will close and the door below the pool will open, so your biomass will slide down to the red pool at the bottom.
  
  
• Absorb your biomass again and smash the wooden barricade.
  
  
• Get the DNA ''Electrosis''.

• Containment unit no. 7 is in the Nuclear Power Plant.
  
  
• You must have ''Harpagorrea'', ''Photokinesis'', ''Keratosis'' and ''Parasitism'' abilities.
  
  
• In the water use ''Harpagorrea'' to pull the plug below and swim down the pipe - also your energy must be full.
  
  
• Use ''Keratosis'' to shield against the first explosive on the right - there is a red pool on the right.
  
  
• Go down below, remove the grid from the electrical switch and fully recharge.
  
  
• Enter the door and flip the lever - this will activate the laser and will open the door on the right.
  
  
• Shred the guard below and use ''Parasitism'', send the very guard towards the door on the bottom left, grab the second explosive, explode and break that door.
  
  
• Slide down using the tunnel on the right, break the unit and absorb the DNA ''Electrosis'', ''maximum energy level increased''.

• Containment unit no. 8 is in the Armored Warfare Facility by the exit.
  
  
• Use the recently (?) acquired ''Keratosis'' to break the door on the right by bringing down the explosive.
  
  
• Squeeze in the door and smash the unit to absorb ''Electrosis''.

• Containment unit no. 9 is in the Bunker - the last level - nearby the first nuclear core you see.
  
  
• Smash and kill and squeeze in the black door.
  
  
• Break the unit to absorb ''Polycheiria'' - ''grow a third prehensile tentacle''.

This is my first guide and it is about on how to solve the in-game puzzles to absorb DNAs from containment units.
I will not update this guide as of now.

I also worked on a story to fit the CARRION in, make sure to check it out:
