Quicklinks: What Happened to the Colonists? | Follow an Old Friend

What Happened to the Colonists?

After taking the elevator to the top of the ARK, you'll have a simple puzzle where you have to interact with points of interest. Interact with the following:

Interact with Sarah.
Interact with Ryan.
Interact with the corpse behind the counter underneath the fallen cabinet.

Walk further to the back of the room and a door will seemingly open by itself. Another A.S.E. is flying away. Follow it, and you will find a room full of dead people, leading to a cutscene and ending this Objective.

Follow an Old Friend

The beginning parts of the "Follow an Old Friend" Objective involves a little exploration. Follow ACE until you see it floating across the bridge. When you try to catch up to it, it will go into a locked door to the left.

Backtrack across the bridge and turn left. You'll pass underneath a half-open door, and then you'll have to unlock two doors with AYLA. On the other side, you'll find a STREAME transmitter.

Head back across the bridge to the room on the living quarters' first floor that is holding a STREAME splitter.

You're going to need to get into this room, but the door is locked.

Fortunately, there is a vent that AYLA can enter. Send AYLA in, then move the STREAME splitter so that it can no longer reach the door ACE went through.

Cross back over the bridge and aim the STREAME transmitter at the STREAME splitter on the first floor across the way.

Cross back over the bridge again to the room with the STREAME splitter. You can now retrieve a STREAM reducer from the room on the right. Take the reducer back to the STREAME transmitter. Place the STREAME reducer in the white box in front of the STREAME transmitter. Aim the STREAME transmitter at the STREAME receiver one floor up.

Turn to your right and climb up the ladder to the second floor of the living quarters.

Run around to the other side of the second floor and you'll find the room with the STREAME receiver, along with a vent.

Send AYLA into the vent and have it pick up the STREAME reducer in this room. This will cause the door to open.

Take this second STREAME reducer and fly it down to the first floor with AYLA. Deposit it here, in front of the red line connecting to the door you want to open.

Once this is in place, send AYLA across to the other side of the first floor.

Have AYLA go back into the room with the STREAME splitter. Move it back into place so that the beam is once again hitting the door you want to open while passing through the STREAME reducer.

Release control of AYLA.

Travel back down to the first floor and redirect the STREAME transmitter to the STREAME splitter across the way. It will pass through two STREAME reducers, providing the correct amount of power to finally open the door:

Proceed through the newly-opened door and you'll see another hologram. Interact with it and you'll transition to a cutscene.

Deliver Us Mars Chapter 7 Collectible Locations

You can find the Security A.S.E.'s at the top of the elevator you take at the beginning of Chapter 7.
