How To Reach The Sleeping Quarters

When gameplay resumes, poke around the mess hall as much as you like, thentake the elevator directly in front of youto meet up with Sarah and Ryan. When the three of you enter the crew quarters, speak with Ryan and Sarah individually, thenexamine the body behind the counternear where Ryan is standing.

After checking out the entrance area,move deeper into the quarters, crouching and vaulting as needed. Follow the ASE unit across the bridge to the next room, and approach the robot in the far corner by the window. When you climb over the debris, a cutscene will trigger.

When the cutscene ends,decrypt the hologramnext to Claire. After it finishes, you’ll be in a stairwell - climb up to reach the sleeping quarters.

Continue straight through the sleeping quarters and you’ll find a door that AYLA can unlock. Do so, and view the hologram inside. Have AYLA open the next lock, and ACE will escape through a door in front of you.

How To Follow ACE Through The Locked Door

Cut open the floor panel in the hologram room to activate an MPT emitter, andaim it at the splitter across the gap.The beam will be sent to the door that ACE fled through, but you need to reduce the power output considerably.

Go across to the room with the splitter andsend AYLA in through the aperture.Have her move the splitterslightly back from the emitterso that its side beam goes past the resistor in the adjoining room. If positioned correctly, it willopen the side door, allowing Kat to retrieve the resistor.

Place the resistordirectly in front of the emitterand fire it at the panel on the second floor. It will pass through a second resistor there;send AYLA upto move the second resistor, opening the door and allowing her to bring the equipment back to Kat.

Finally,place both resistorsalong the beam leading to the door lock, then fire the MPT back at the splitter. This should provide enough power reduction to open the door.

How To Align The Labos MPT Dish

Once you’re inside,decrypt the hologramin front of the door to Rosa’s quarters. Watch the cutscene that follows, and you’ll be returned to the Habitas bridge. Use the terminal next to Sarah to start aligning the Labos MPT dish.
