Get the car started.After the opening scene, interact with your car three times as you step out of the café to get it running. Note that doing so affects the ending, thus it may be better to leave it alone until the very end if you are going for all the endings in one go. See the 'Endings' and 'Optimal Path' sections for details.
Reveal the trail.In Site C (GZ), look for the deranged man sitting by the fireplace in the decrepit building overlooking the lake and interact with him four times.
Get the modified loudspeaker device.In Site C (GZ), find the echo (#11) within the solitary tent by the lake. After going through it, make your way to the other end of the area past the crater and pick up the modified loudspeaker laying on the ground next the fencing.
With the loudspeaker at hand, you have a chance of getting rid of the ghosts wandering the sites. You have only ten shots for it though, so better be steady on the trigger. Note that the loudspeaker is also required for two other achievements: see below, as well as Foreshadow in the 'Endings' section.
Make a new friend.In site B (Hearth), once you get hold of the hotel room keys, check out all the rooms on the second floor of the Pelican Inn until you come across a man that waves at you for a second before vanishing. Note that he may not be there at all if you come into contact with any of the three ghosts wandering the sites, so take care.
Trigger the final radio conversation.With all three sites contained, return to the comms room in the Orchard and answer the call from Helen before moving on to the Echo-Garden Facility. Note that the first and the second containments also trigger additional dialogues if you return to the comms room in between. However, listening to those are not required to for the achievement.
Access the haunted terminal.Gain access to the 'haunted' terminal found on the second floor of the Echo-Garden Facility: in the room adjacent to the one where you find the access card. To be able to do so, you first need to collect the modified loudspeaker from Site B (Hearth) -see above- and get rid of the three ghosts wandering the sites.
The one in Site C (GZ) can be seen wandering around the tents in the middle, the one in Site B (Hearth) can be found on the road blocked by police barricades on both sides (echoes #14-16 below), while the third one in Site A (Last Stop) can be triggered by finding the echo next to the crashed van on the main road (#17).
Containing a site does not affect the ghosts at all, you can even return to a site later and find them around their usual spot - although it may need some time to show itself. Take care not to come into contact with any of them though; as doing so makes the ghost in question vanish, never to be seen again, thus lacking you out of terminal and the respective achievement, as well as the Foreshadow ending.
Likewise, know that you are locked to the Foreshadow ending once you get rid of the three ghosts and are not able to get the Salvation or the Survivor endings in the same run, unless you have a previous save in which at least a single ghost is still wandering around.

If you want to get all the endings in a single run, see the 'Optimal Path' section below.
Seal your fate.This is not a fully-fledged ending at all, but rather an alternate cut with a slight nod to the Resident Evil series. While on the lower floor of the Echo-Garden Facility, instead of getting connected to the neural link interface, turn around and pull the two levers found on the sides of the door to get this ending. Make sure to save your game beforehand to not lose progress.
Get the ending.Reach the Echo-Garden Facility with your car crashed somewhere in between but neither dealing with the ghosts nor finding all the collectibles to get this ending.
Get the ending.Reach the Echo-Garden Facility without starting your car and neither dealing with the ghosts nor finding all the collectibles to get this ending.
