After going down the elevator to the desired part of the building, go down the stairs. In the first part of the corridor you will be attacked by Necromorphs.
Go through a few more empty corridors until you are attacked again. In the same corridor you will find a ladder – go up it. In the next room, next to the gate, a Necromorph will jump on you.
Text Logs 4/4 – On a table in one of the corridors.
While crossing the bridge, you will be attacked by a small horde of Necromorphs – it is best to stand in the middle of the bridge and watch each end so you can kill creatures from both sides. Also watch out for monsters crawling along the ceiling – these enemies are especially persistent and hardy.
Cross the workbench room and empty all the lockers here. Now go to the freight elevator, which will take you down. Get ready for a little fight with a few monsters.
Audio Logs 4/6 – In the workbench room, near the wall.
Move on until you reach a corridor with several blocked doors (near them there is a slot for powering the cores). Clear the area of the monsters, and then one of you should take the kinesis core and put it in the slot next to the door next to the stairs.
Chains Upgrade 7/10 – In the hallway upstairs – you have to use the power core to unlock the passage.
In the next corridor you will find lockers. Move forward, crossing the new part of the tunnel, where you will find more lockers worth searching.
Audio Logs 5/6 – On the floor in most of the corridor with lockers.
Go to the next part of the tunnel where you will be met by some Necromorphs. Go to the door on the left. Finally, you will reach an elevator that will take you up.
Weapon Parts 6/9 – On a crate, in the tunnel, in front of the hallway leading to the elevator.
After leaving the elevator, fight off the attack of the Necromorphs and go up the stairs.
Audio Logs 6/6 – On a crate, in the tunnel, after exiting the elevator.
The next corridor will lead you to a fork – the door on the left is inactive, so move forward where you will find another elevator and a raised bridge.
Weapon Parts 7/9 – Under the table, near the inactive door to the left of the fork.
Go down the stairs – you will notice a strange creature kneeling. Get rid of him and get ready to fight the horde of Necromorphs that will appear here. After clearing the place, go up the second ladder – you won’t be able to lower the bridge.
Now go to the next corridor where you will find an elevator. After that, you will find yourself in a room with a work table and a locked door that can be opened with a torque rod.
Blueprints 2/2 – Near the hull, inside the supply room, which can be opened with the moment bar.
After restocking, continue walking. You will find yourself in a warehouse with a freight elevator in the middle. Approach the panels and activate the elevator at the same time.
Of course, the elevator gets stuck halfway through and you will be attacked by several waves of Necromorphs. It is best to be next to each other in the corner of the room and keep an eye on your companion. After a long fight, when the elevator goes down, open it with your companion and take the supplies.
Weapon Parts 8/9 – Inside the supply crate.
Upgrade Chains 8/10 – Inside the power crate.
Weapon Parts 9/9 – Inside the supply crate.
9/10 Upgrade Chains – Inside the power crate.
After looting this place, proceed to the next door, which will lead you to a corridor with several displays. Turn right behind the shelves and go to the elevator that will take you to the beginning of this stage.
EarthGov Artifacts 1/1 – On a shelf in the corridor with a workbench and displays, next to the elevator.
Upgrade Circuits 10/10 – On the wall in the corridor with a workbench and displays.
