Alien: Isolation guide: Mission 4 Walkthrough

Mission 4: Seegson Communications

Once you arrive head off the elevator and speak with the Synthetic behind the glass ahead of you. He’ll tell you to take a seat, but ignore him, and instead head down the stairs and all the way down the hallway to the room at the far end. Here you’ll have a brief encounter with an Android, but again, ignore him and pick up the Motion Track on the desk inside the room. Now interact with the terminal in the corner and browse to the Utility Folder to override the nearby door and open up the staircase.

Head out the room and into the door you just opened on your left. Make sure the androids don’t see you and head up the stairs to the top and into the hallway. Explore the area and then head down the end of the hall and make your way through the open room in this area to pull the lever to open the door. Now turn left and move up the stairs, using your Access Tuner on the door marked Maintenance to get through.

Loot the room and then climb into the vent, following it until you witness a brief scripted moment and continue until you exit the vent. Now you’ll need to gain access to the elevator all while avoiding detection from the nearby camera and android.

Head past the murdered human and use the Access Rewire to shut off the camera and then backtrack to the elevator to head up to Comms Control.

Once you reach Comms Control you’ll need to Contact Verlaine and the Torrens. Save your game if you want and then head through the door right next to the save station and up the stairs. Turn right at the top for extra supplies, and left for the mission objective. Once you reach External Communications you’ll receive an update to Find an Alternate Communications Terminal.

Return to the ground level and move into the open area ahead, veering right to drop into a floor vent to avoid the attention of the room’s patrolling androids. Exit the vent through the forward opening and move along the right wall into the Internal Communications and Monitoring Hall areas. Once you pass through the doorway you should hang a sharp right and head into the Monitoring Hall. Sneak through here and through the Human Employee Recreation wing past the vending machines and counter, and into the next hallway.

Watch the android deactivate Samuel’s transmission and once he leaves head into the large room and interact with the console to play a three part mini-game that will end in a short cut scene.

With the cut scene out of the way it’s time to make your way back through the level to complete your mission and escape. But don’t get your hopes up quite yet. Your time is now going to be spent dodging curiously angry androids and one heartless alien creature. Glance behind you to the right to spot a small room with a save station. Grab the EMP V.1 off the table and move into the next room to climb into a vent to the left of the door. Follow the shaft until it ends and then look for another just to the right of the room’s exit. Head through it until you find yourself just outside of Internal Communications.

Move up the stairs to your right to head through the Human Employee Recreations area and move carefully to avoid the patrolling androids. We highly suggest checking your Motion Tracker often to keep track of movement.

Pass direction through the Monitoring Hall and out the door you originally entered through. Beeline straight for the vent and back out the floor vent you climbed into on your way in. Save your game if you want and use the elevator to return to Comms Security Surveillance.

This should place you in the hallway where you disabled the camera after watching the android brutally beat the human to pulp. Make your way back through the vent and wait for the android to move away from the control booth before exiting and sneaking forward through the Human Employee Recreation room on the right. Follow this hallway all the way around to the opposite door and across the hall to move into the Reception Area.

Head down the stairs and turn left once you’re at the bottom. Be careful of the androids near you and tread carefully until you reach the elevator back to the Lorenz Systech Lobby.

Once you exit the elevator you’ll be in the area where you watched the Xenomorph kill the four angry humans. Make sure to crouch as you move through the area, and avoid the androids laying on the ground, as any loud sounds or combat will bring the alien to your position. Head all the way across the room back to the Transit Station and take a right to pass through another door into the Towerlink Transit System. Head over to Towerlink 01 to call the car and take it to Solomon’s Habitation Tower. Once you arrive at your destination you’ll need to immediately hop on Towerlink 03 and ride it over to the Scimed tower to finish up this mission.
