leads back to the Hall with Broken Windows. (Long Magazine 2)

As you round the corner in the Hall with Broken Windows, an Ooze will drop from a vent. Defeat it. Avoid entering the Laundry Room.

Reenter the Bunk Room previously locked with the Anchor Key. Restock machine gun ammo and equip the machine gun with the Long Magazine 2 upgrade if available.

Proceed to the Bunks and Restroom area.

Upon entering, Rachel will laugh. Move around the lockers and enter the restroom.

As you step down the stalls, an Ooze will emerge from the next bunk room. Stop, back up, and defeat it from a distance.

Further into the next bunk room, Rachel will drop from a ceiling vent behind you. Immediately turn and attack her with the machine gun. If she charges rapidly, she is retreating. Stop firing when she dashes frantically and screams, as she will retreat into a vent.

If you need more ammo, return to the Bunk Room with the anchor marking.

Exit the Bunks and Restroom and return to the Hall with Broken Windows.

As you approach the stairs, an Ooze will crawl from a vent in the alcove. Defeat it quickly as Rachel's boss music triggers.

Run towards the stairs and wait for Rachel to emerge from the left corridor. Attack her as soon as she appears. She should retreat if hit immediately.

Enter the Stairway Area and descend the stairs. Open the door at the bottom.

As you enter the Passage, Rachel will fall from a vent above. Shoot her repeatedly as she recovers. She should retreat before reaching you.

Run left down the hall and enter the Kitchen.

Open the door to the Lounge and enter.

As you approach the vending machines, three Oozes will drop from overhead vents. One will appear in front of you.

Rachel will eventually fall from a vent near the vending machine. Parker will rejoin you as the Oozes attack.

Run towards Parker, then turn and throw a hand grenade at Rachel and the Ooze group.

Engage Rachel with your remaining ammo. Use a hand grenade if she and the Oozes are grouped together. This is her final encounter in this area, so she has more health.

Be prepared to heal as Rachel will likely hit you. She will attack only you, even with Parker present.

Upon her defeat, Rachel will drop the LIFT KEY. Pick it up and exit the room into the Elevator Hallway.
