Alien: Isolation guide: Mission 18 Walkthrough

Mission 18: Tomorrow, Together

Your first objective to Escape Sevastopol is quickly overridden by the new objective to Initiate the Docking Procedure. Use your Motion Tracker to locate a terminal that will only work if you Restore Power and then dive into the crawl space by removing the vent cover on your right. Once inside follow the wires to a drop off and interact with the nearby panel to Reboot System. Now backtrack to the console by the vent and use your Access Tuner to update your objective to Activate Guidance systems

Now head directly behind this console to the other side of the room and use your Access Tuner to once more update your objective to Engage the Docking Procedure. Now head to the center of the room and use the terminal here, scrolling to the Utility folder and selecting the Initialize Docking Clamp command. Your next task is to Extend the Personnel Umbilical. To do this you’ll need to head to the area you activated the guidance systems from and pass through the door in the middle of this area. Head up four flights of stairs to an upper control area and this will trigger a short conversation that leaves you with another task change, Extend the Maintenance Rig. Use the terminal right here and head to the Utility folder, executing the Extend Maintenance Rig command to get your final objective for the moment… Get to the Airlock.

Make your way back down the stairs and to the right of the center of the room. Turn right into the changing room and interact with the spacesuit closet to activate a devastating cut scene that ends with you waking up in the Alien nest.

Now it’s time to make your way back through the ship and Get back to the Airlock.  Start by making your way forward through the overgrown tunnel. We suggest having your shotgun or Flamethrower handy to deal with any face-huggers. Continue through the area, you’re only given one possible direction, until you reach an area where transit shuttles are zooming past. This part can be a bit tricky as you will have to run across the tracks and duck into the designated areas in order to avoid being smashed by the shuttles. Once you spot the Maintenance Office run inside and hop in the vent, working your way to the right. There are quite a few face-huggers here, take them out easily with your flamethrower or blast them to pieces with your shotgun. Exit the vent onto an elevator and then climb down and out of the shaft.

This are should look familiar, as it’s the area you made your way through in Mission 17. Make your way back through the flames and destruction until you reach the airlock once more. Change into your spacesuit and once you regain control head out into space. Use the nearby lift to reach the upper level and then follow the catwalk until you make your way to the trolley. Interact with the trolley to continue, climbing out of it at the end.

Follow the stairs to the top and your objective will update to Prime the Release Mechanisms. Hit up the consoles on either side of the area, and then once you’re done with both your objective will now be to Blow the Emergency Release Bolts.

Approach the glowing device on the floor and set each of the bolts to Active. This will trigger a cut scene that ends with your final objectives being to Get to the bridge and Meet Verlaine on the Bridge. Making your way through the Torrens and follow the on screen instructions to complete the game and enjoy the ending.
