Once your elevator ride comes to a quick stop you’ll need to head forward towards the fire and climb into the vent on the left side of the corridor. This should update your objective to Find an Alternate Elevator.
There is only one way you can move through the vent, so follow it until you drop to the floor below, receiving an even newer objective of Find Compression Cylinder to Repair the Elevator. You might also want to make use of the save area here, but that’s completely optional.
Now make your way along the corridor and hop into a vent on the right side of the wall, following it until the only exit. Emerge to find three humans just a few feet to your left. Walk towards them until you spot a vent cover on the floor and drop inside.
Once you enter the vent turn all the way around and crawl forward, turning right when you can’t go any further. Follow the path until you hit another right turn, then take a left when you reach the open area. Continue forward until you are forced to turn right and climb out of the vent next to a ladder.
Walk through the corridor until your objective updates to Find a Way to Open the Door to the Warehouse, the continue moving forward until you pass into a large room. This will once again update your objective, this time asking you to Use the Requisition Android to Access the Components Warehouse.
Approach the idle Synthetic inside the glass case, updating your objective for a third time to Find a Way to Power Up the Requisitions Android. From your position looking at the Android hang a left and travel to the far end of the room, heading through the open door and saving your game using the station on the left wall. Pick up the device on the table to gain access to an upgraded Access Tuner. Just what we needed, maybe now we won’t need keycards.
Exit this room and walk along the wall on the right until you reach the first door you entered through. Exit back into this corridor and climb up the ladder in the center of the hall. Move forward and choose the option to Use Security Access Tuner on the console in the room. This will update your objective to Activate the Requisitions Android at its Booth.
Leave the room, passing the ladder and use the Access Tuner on the door to the right. Head inside and loot up, then use the Sevastolink terminal to view the Shared folder and more specifically the Elevator Out message. Through this you’ll learn that you can find the part using either a keycard to open the door, or the Android. Since we couldn’t find the keycard around anywhere, and were almost ready to wet ourselves due to the noises around us, we went with the logical choice… the Android! If you found the keycard though, and you’re looking for the repair parts, just find Components Storage – Row 1 – Stack B.
Depart from this room and back down the ladder and into the room with the Android. Walk up and press the button on the control panel to activate the android who will then lead you to Components Storage, updating your objective to Retrieve the Compression Cylinder.
Once you’re in the storage room ignore the Android and head to the right side of the room and use the Move Down command four times on the stack here. This will allow you to step across the area, without stepping in a puddle of electrified water.
Once you’re one the far end head to the furthest left stack and choose the option to Move Down. This will allow you to collect the Compression Cylinder thus updating your objective to Replace Component in the Elevator.
Exit Components Storage and turn left, following the corridor until you pass through a door. Turn right now and head into the area just beyond the Technician Training sign. From here it’s a straight shot to the elevator. Once you arrive simply choose the option to Replace the Compression Cylinder, then hop on and activate the elevator to head the Synthetic Fluid Plant.
After a short ride you’ll arrive and you’ll get an objective update to Find Exit to Synthetic Fluid Plant. Head through the door in front of you to a room with a hanging assembly line. Move forward onto the left catwalk. It was about this time that we watched the Alien drop across the area in front of us, we didn’t run into any issues as we continued but you might want to be careful at any rate.
Once you pass through this area and into the Facility Administration area you’ll pass through one more door and then turn left and follow the narrow corridor as far as you can, going through this final door where you’ll find two people with guns. Sneak past them and exit the room on the opposite side. Keep moving until you reach the elevator and choose to send it to Scimed Tower Transit. This will update your objective to Get to Sevastopol SCI/MED Tower and bring the mission to a close.
