Get to San Cristobal Medical FacilityElevator that takes you to San Cristobal Medical Facility is in northwestern Sevastopol Scimed Tower. Before you reach this location make sure not to miss the computer terminal that reveals this part of Sevastopol Scimed Tower.
Get into the San Cristobal Medical FacilityOnce you are inside the Medical Facility and you are properly introduced with a new character find an air vent and go through it. This is a long tunnel. Once you jump down into the new area be sure to activate another map terminal. Enter the room toward west. You can save the game here. New quest objective is given upon completion of dialog with the new character.
Find Morley’s Office
Morley’s Office is to the south. Before you perform Emergency Override above the locked door near the Doctor, go through the nearby air vent. It leads north toward Assessment Room. It hides an ID Tag and map terminal.Head back and go through the locked door. There are no enemies here. Use this time to save the game inside the central room with two square tables. One of the tables holds “Left Out of the Loop” audio log, while inside a small hospital room in southeastern area is ID Tag: C. Burrows.Morley’s Office has Senior Consultant sign above it and you have to use the security Access Tuner in order to breach it. Use the personal computer inside his office and find “Hospital Quarantine” file under shared folders. This file hides pass code: 1702. Once you read it the next quest objective begins. Inside the same personal computer there are other Archive logs like “Low on Meds” and “An Outpost of Progress? #3”.
Find Dr. Morley’s KeycardThis is where the fun starts. As soon as you step over small stairs toward the quest objective the Alien appears. Rush by him as you don’t want to waste time here and head to the doors to the south. This doors requires passcode we have acquired earlier. Type 1702 and enter.
How to avoid the alienAlien always stays close to your current location and patrols the area. Whenever it’s around you are basically playing a game of cat and mouse. Move when he has its back turned to you and is far away. Always crouch. Use hiding spots under tables (you are almost completely invisible there) and when you do not see him use the motion tracker. If he is real close (a few steps away) turn off the motion tracker because that can trigger him. Keep going south until you come across a large San Cristobal Medical Unit Board. You’ll finish your objective here.
Investigate Rooms on Dr. Morley’s RoundsPipe Bomb (V.1) Blueprint
Once you leave Staff Quarters area head east through a small tunnel. Inside the first room to your right, on a table, is the blueprint.Inside the same room is the save terminal. Use it wisely as you have the Alien searching for you (don’t save just when you are about to be killed). Following the tunnel you end up in front of the largest Medical Facility area. There is a map terminal close by. Inside the first room to your right is Personal Terminal with archive logs: “RE: Recovery Rooms” and “Medical Record 1”. Your final quest objective goal can be found inside A-29 Room. Search for the body on the ground for the Keycard.
