Find the source of the signal | Walkthrough Alien: Isolation Guide

Last update: 11 May 2016

In this mission you'll play as Marlow (he's telling you what happened). Before you start the mission, press (by default - space) to use the sensor. It shows you where to go.

The right dial should move right when you get closer to the source. There is no alternative route so you shouldn't get lost.

Walk up to the rocks and your objective will be updated. To go further, turn left and approach the ledge. One of your companions will pick you up.

There is only one way up so you won't get lost. If you have problems, use the sensor (space) and follow the signal. You'll reach rocks that block your way. Plant a bomb, get back and wait until your companions join you.

Turn around and approach another ledge. Wait until someone picks you up and head straight towards the alien ship.

Go to the higher rocks and enter the alien ship. Follow your comrades and you'll reach the source of the signal.

Cross the room. You can see a ledge, your crewmate will help you get there.

Go to the end of the corridor and you'll reach a device that emits the signal. Turn it off and go back to your crew.

You'll see a light in the middle, go towards it.

Walk up to the platform and go down. Approach the end of the platform to start a cutscene.
