Alien: Isolation guide: Mission 10 Walkthrough

Mission 10: The Trap

After regaining control of Amanda from the previous mission’s ending your objective should update to Collect the Flamethrower. Head inside the room that just opened to your right and grab it from the counter, also making sure to grab the other supplies tucked away on the shelves. With your newly acquired weapon head back to the main area in order to update your objective to Go to Lorenz Systech Spire.

Before you head back out into the station take a moment and enter the side areas to gather up any needed supplies. Once you’re ready exit the main room and take the short hallway just to the right of the save game feature.

Backtrack through this area, turning left when you spot the Towerlink Transit system sign. Pass under the sign on the right and continue down the stairs to Towerlink 02. Look for a sign that reads Destination Lorenz Systech Spire and call this transit, boarding it once it arrives.

Upon arrival at your destination head to the left and up the stairs with the Lorenz Systech Lobby sign above it. Your objective will update to Get to Server Hub and you’ll need to go through the door with the Lorenz Systech Lobby and Security signs posted above. Turn left to return to the large room where you first encountered the humans back in Mission 3.

Approach the center of the room and follow the two people here up the stairs to the right, taking another right and moving forward until you reach the Tech Support door on your left. Head through the door and down the three flights of stairs, passing under the Tech Support sign before moving forward and taking the small set of stairs on your right. Head into the Tech Support HQ booth and access the Sevastolink Terminal; browse to the Utility folder and use the Door Control option.

Now your objective should update to Seal Off the Stairwell, and you’ll see a synthetic wander through the area. Toss a flare to distract him and sneak inside Server Hub Reception once he goes to investigate. Once you’re inside head up two flights of stairs and take a right, passing through the door marked Seegson Security and Tech Support. Inside this room you’ll find plenty of supplies as well as access to the Seegson Security area. Feel free to use the terminal nearby and browse down to the Utility > Open Cells option to grab some more loot.

Backtrack out of this area and turn right before you head up the small set of stairs. Approach the device with cables leading to it and interact with it to initiate the lockdown with your Maintenance Jack. This will lock down the area and place shutters over the entrance to Seegson Security as well as the Lorenz Systech Lobby.

Now you’re going to want to pull out your flamethrower and keep it ready as the Alien will start to patrol the area you’re in. Use the flames sparingly to drive the Xenomorph away, making sure to confirm his movements with your motion tracker when he dives back into the ceiling vents. Be cautious as you move throughout the next area, and keep an eye on your flamethrower fuel. We highly suggest hiding when you can, as you’re going to need this fuel later on in the level.

Once the area is clear enough to move head back through the only open door into the stairwell. This time you’ll need to climb to the top floor and through the door up top. Turn left and approach the nearby lockdown device to lock off part of the stairwell and update your objective to Lock Down Server Hub Reception Corridor.

Return to the stairwell one more time, heading down one flight and choose the Override Door Mechanism option on the device next to the door here. This will open the door and allow you to move inside and access the terminal behind the reception desk, which will also update your objective to Activate Ricardo’s Override Command.

Browse down to the Shared folder and choose the Folder Code option, this will reveal the Audio folder’s code, 7789. Use this to listen to the audio log then browse back to the Shared folder and select the Bypass Program option. This should now allow you to access the previously locked Utility folder and choose to Initiate Lockdown.

Keep an ear out for the Alien and head left from the desk once your objective updates to Lock Down the Server Farm. Head through the door to the Server Farm and either kill or sneak around the hostile Android in the area. Grab the Noisemaker V.2 from the table in the room and turn around, heading through the door ahead to save your game using the save game terminal. Turn right when you’re finished and head through the unmarked door, up the stairs, and then down another stairwell. Move to the left wall and pass into the small corridor with the Sevastopol Servers sign above it.

The next room will most likely be patrolled by both the Alien and a Walking Joe, so keep your weapons ready as you sneak through the area. Once the coast is clear head to the Sever Control Door and use your Security Access tuner to grant yourself administrator rights. This will trigger all the doors around you to open and update your objective to Escape the Server Hub.

Now it’s time to backtrack exactly the way you came, passing the save gamer terminal and heading back up the stairs you came down just moments before. Now that you’re back in the Server Farm you should see a door to your right that leads to the Server Hub Reception area. If it isn’t accessible you’ll need to use an alternate route. Head for the door at the bottom of the tiny set of stairs with the Server Farm sign above it. Pass into this room and through the door on the right, making sure to use the Access Rewire on the wall. Remove Door Access and activate Air Purification before continuing through another door just ahead. Turn right here and use your jack to remove the lock on the door and enter Server Hub Reception.

Pass through the reception area and back out into the stairwell, heading down two flights of stairs and back into the Tech Support area. Move forward from here and up the next three flights of stairs to head into Lorenz Systech Lobby, which should trigger your objective to update to Take Elevator to Gemini Exoplanet Solutions

Head up the small set of stairs right outside the door, and then up the next flight just to the left. Pass through the door to find the elevator on your left and take it to your destination. Once you arrive step off and save your game with the handy mechanism nearby. You’ll also receive another objective update, Restore Access to Distribution. To do this you’ll need to head left and up the stairs on your right and through the door. Follow this corridor until you see the door on your left and then continue in until you spot the Synthetic at the terminal behind the glass. Avoid the motion scanners in the area and if the Alien shows up you’ll need to scare him away or hide until he leaves.

Keep an eye out for the dead body at the side of the room and search it to find an upgrade for your Cutting Torch. Approach the door next to the glass, being careful not to give your position away to the motion scanners around you. Once the area is clear use your Cutting Torch  to remove the plate in the center of the door and interact with the level to gain access to the room.

Deal with the Synthetic inside and then use the terminal here. Scroll down to the Utility folder and select the option to Reinstate Distribution Systems. This will update your objective to Find the Breaks to Bring Gemini Facility Online. Backtrack out the entrance of the room and turn left, passing through the unmarked door and toward the objective which is indicated on your Motion Tracker. Turn left at the corridor’s end and follow the next hallway until you see the Depot sign. Use the Emergency Override to open the door and head inside, hugging the left wall and climbing the ladder once you reach it. At the top you’ll need to head down the corridor and turn to the left into the room and through the next room as well.

The room you’re in now should have several work stations and a door that can only be opened using your Maintenance Jack. Look for the several circuit breakers along the fall wall and approach them to be given the option to Reset Breaker. This will update your objective to Trigger the Analysis Lab Break Switch. From here head back down the corridor or use your jack on the nearby door. Either way you’ll end up back at the ladder you climbed up to get to this level. Climb back down and hub the right wall, exiting out the Enrichment Laboratory door and turning left. Follow to the end of the corridor and choose the option to Climb, turning left to follow the crawl space until you can exit into a room on the right side near the end. Head through the door along the left wall and wait for the camera to move from the nearby door before going through it. Loot this room before exiting through the unmarked door and following the left wall until you find another breaker. Reset the break to update your objective to Initialize Distribution Conduit. Backtrack out of this room and into the hallway with the camera before crossing through the unmarked door and looting the room beyond. Head through on of the Maintenance Shaft Access hatches and into the crawl space within. Turn left and follow the crawl space until you can climb out of the hatch and into another corridor. Follow to the end, where the Depot sign hangs, and into the door on your right. Head through the door before you and to the middle of the room where you can access the terminal. Scroll to the Utility folder at the bottom and choose to Initialize the Distribution Conduit. Next select the Service Request option before exiting. Stay near the center of the room, moving just a few feet forward from the terminal to pull the level to Stabilize Energy Flow. Now move counter-clockwise around the center tower to find another level, pulling it to Stabilize Energy Flow once more. Once complete your objective will update to Take Freight Lift to Project KG348.

Exit the room from the opposite side you enter, and head through the Distribution door. Turn right through the next Distribution door on your left. Descend two flights of stairs and grab the map halfway down, heading through the Quality Control door at the bottom. Walk around the desk with the dead human and choose to Call Freight along the right wall. This will open up a hatch to the crawl space on your left, head inside and follow it left, exiting into the second room on your left.

This should deliver you to a room with a set of stairs and a wailing alarm. Walk past the stairs and through the Lobby door and then board the elevator to Project KG348.

After exiting the elevator your objective will update to Access the Project KG348 Research Labs. Move forward and through the closed Reception door on your right, passing all the way through the next area and through the unmarked door. This will lead you to an area full of signs with directions to Project KG348. Follow the signs and use your Cutting Torch on the far door.

Once inside the room with the ladder grab the map and receive an updated objective asking you to Restore Power to the Lab. Climb down the ladder and exit the area using the door on your left, following the corridor as it curves right and leads you through another door. Passing through this door will reveal a severely battered Android, turn right and move counter-clockwise around the area, passing the Analysis Lab corridor until you get to a very brightly lit room. Head up the stairs on your left labeled Synthesis Lab and enter the next room. Look for and choose the option to Reset Breaker before turning around and saving your game.

Your objective should now update to Activate Primary Alarm System. Backtrack down the stairs, turning to your right at the bottom. Now travel clockwise around the corridor and enter through the open door on the right side of the hallway. Use your Security Access Tuner on the console and fend off the Alien if it makes an appearance.

Once your objective updates to Escape the Lab head out of the central room and turn right, moving clockwise around the corridor. When you reach the door you’ll endure a short scripted scene before once more having your objective update to Get to the Airlock.

This is why we told you to save your flamethrower fuel. The Alien is a massive pain in the neck during this part of the mission and you’ll need to head back around the area to the airlock. Once you reach the airlock you’ll need to Pressurize the Airlock, which will update in your objectives. Use the button nearby and then hide until the airlock is ready. Once the objective changes to Get to the Airlock make your way into through the now open door as quickly as possible to trigger a cut scene. Once the scene ends run into the next room and choose the option to Change, which will bring this mission to an end with a nifty little cut scene of Ripley soaring through space.
