You’ll begin this episode in the Emergency Communication Room. There’s a file in the room, as well as a Grenade and some ammo. Scan next to the files to find more ammo. Leave through the door and Raymond will hand you the Iron Anchor Key. Listen to his directions and follow them, going down to the lower floor and using the key on the large, anchor-imprinted double doors. Go down the stairs, collecting the Green Herb along the way. Keep going and you will come across some slot machines and an escalator. One of the slot machines to the right of the escalator has a Hand Print on it, so scan the area.
Grab the file from the side of the fountain in the center of the room. Then pick up the Handgun Ammo Case next to the locked door to the right of the fountain. Head up the stairs and try to get through the door. Unfortunately, you can only get through this locked door if you place a certain amount of coins on the scale propped against the door. Pull the lever to your right to bring the power back on in the area. Now go down the stairs and press the big red button on the fountain. The water will turn red and B.O.W fish will begin spewing from the fountain and lunging at you. Take out your pistol and kill all of the fish, being sure to scan them afterwards.
A single coin will drop from the fountain. Take it and insert it into one of the lit-up slot machines to play slots. Keep going until you get the Bundle of Coins reward. If you get nothing, the machine will spit your coin back out at you. Take your coins back up to the scale at the top of the stairs. Feed the scale three bronze, two silver, and four gold coins to reach a total of 107, which will open the door. Inside you will find ammo and a box to customize your weapons in. Scanning the area next to the box will reveal some Custom Parts which you can use right now. From here, you will have to climb down two ladders before climbing up a third on the other side of the room. Jump down at the end of the hallway.
Heading through the double doors on the other side of the room will bring you to another circuitry puzzle.
Circuitry Puzzle
The solution to this puzzle is to arrange all of the nodes so that none of the wires are crossing and the nodes are all in the appropriate spots. In this case, the end result should look like a square with its upper left corner chopped off. One node goes in each corner except for the upper left. Then one node goes in the top middle slot, while one goes into the middle left slot. This pattern should open up the door for you.
Climb into the elevator. Turn right upon exiting and follow the hallway instead of the stairs. An enemy will pop out. Kill it or move past it and continue on straight, checking the lockers as you go. You should find a Green Herb hidden in them. Continue on to the left. Scanning to the right in here will reveal some ammo, while heading left and scanning the vending machine will reveal another Hand Print. Leave through the exit and loot the locker for some Handgun ammo. Scanning the boxes outside of the door will reveal still more ammunition. Scan the body on the table, the trunk on the floor, and the sink to get more ammo boosts.
From here, follow the relatively linear path out the door, down the stairs, and to the right. Walk through the blue door and go up the stairs to go through another door. An enemy sits just inside this room. Kill it and keep going to find another staircase. Go up. The right side will have ammo, but you’ll have to scan to find it. Head left once you’ve grabbed the ammo. A B.O.W will fall from the ceiling. Kill it as it’s getting up. The boxes to your left have still more ammo in them if you scan them. Keep moving forward until you reach a sort of bookshelf with binders all over it. Scan these to find ammo again. Leave the area and use the Iron Anchor Key on the locked door that you come to.
You will receive some Machine Gun ammo, a Green Herb, and a Grenade in this room. The next room holds the Machine Gun. There is also a customization area in here, so throw some upgrades onto the Machine Gun while you’re there. A group of boxes will be blocking a door further on in the room. Scanning the boxes will reveal that there is an item hidden just behind the door than you can’t get right now. Instead, head down the hall and use the next door to get into the blocked off room. Search a washing machine to find the item, a Grenade. The crates next to the washing machine hold Machine Gun ammo, but you’ll have to scan for it first. The shelf on the right next to the exit also has Machine Gun ammo on it.
Follow the hallway through the door and walk down two flights of stairs. The locker at the bottom of the stairs contains Handgun ammo. Follow the hallway and scan the floor at the curve to find a Green Herb. Go through the door, scan left for Machine Gun ammo and another Hand Print. Grab the Rifle ammo from the right. There will be a large puddle of blood on the floor. Examine it to begin another boss battle.
Boss Battle: Rachel
When the battle begins you will have to chase after Rachel while shooting her. Eventually she will move into the ducts after you have dealt a significant enough amount of damage. Go back to the area from which you began the battle. There will be enemies there now so watch out. Upon returning to the bunk room, two enemies will drop from the ducts, one of which is Rachel and the other of which is just a normal enemy. Shoot the normal enemy with your shotgun for a one-hit kill, and then focus on Rachel. She will retreat into the ducts again after you deal enough damage. Repeat this process several times and Rachel will seemingly die. However, once you enter the room with the vending machine in it, she will jump out one more time and you’ll have to put her down, along with several basic enemies.
Loot the Lift Key off of Rachel’s body, grab the Custom Parts by the life, and take the lift up.
