Audio Diaries: 17
Power to the People stations: 2
New Plasmids: [Telekinesis 3]
New Tonics: [Elemental Sponge], [Elemental Vampire],
01 - Follow Eleanor upstairs.
02 - Approach the window and watch the cutscene. Enemies will rush into the room and you should retreat to the upper floor. You will have to take care of a turret and a Brute, among others. Remember about the possibility to call Eleanor.
03 - Use the Hack Tool to hack the door lock behind the bars.
04 - Press the button in the room by the locked door. Sinclair in a slightly changed form will appear and you'll have to pursue him. Go down the stairs.
05 - Hack the camera at the cafeteria and take the Audio Diary from one of the tables. Go down the stairs.
AUDIO DIARY: [The Definition of Despair] - Thomas
06 - Take care of the Brute and afterwards melt the ice to acquire two mines. There will be some trap spears in the dark corridor. Eliminate three minor enemies and go upstairs. Go pass the showers and you'll reach a cell complex.
07 - It looks like Sinclair's locked. Never mind that for now and pick up the Audio Diary (go through the hole in the wall of one of the cells). Look out for the camera.
AUDIO DIARY: [Last Two Digits] - Connor
It looks like you've found the second part of the code as well. It's time to go upstairs.
08 - Check out the cells one by one, collecting the Audio Diaries. In block D you will find one from which you'll learn the first two numbers.
AUDIO DIARY: [A Trade] - Dodge
AUDIO DIARY: [First Two Digits] - Mattson
Go through block C into block B. Take a Diary from the hanged man and search the rooms to find the [Elemental Sponge] Tonic. Curiously - here the code has been carved onto the wall.
AUDIO DIARY: [No More Hope Left] - Parson
In Block A you will encounter a Brute and find another Diary.
AUDIO DIARY: [A Generous Offer] - Murphy
You've got the code (2673), so theoretically you can get inside the locked room from the front. However let's check out what the other options are. One of them is to hack the lock to the right, in the distance. Once the door opens, use Incinerate to set fire to the floor right under the box you hacked (by the way, opening the door wasn't needed to set the fire). It turns out that Sinclair has locked himself in a room full of oil, so you'll drive him out of the room quickly.
Another way of getting the code is to go to the toilets (the entrance is opposite to the door with the key lock, you'll have to pay 5$). Once inside, search the tank above the last toilet on the left.
While in the toilet, you can also find a hidden tunnel. Melt the ice in the corner of the room and enter the narrow corridor. The tunnel leads to your friend's hideout. Greet him by throwing a mini turret inside or hacking the nearby Security Bot. Of course you can as well set fire to the oil.
As you can see, there's quite a bit of possibilities. Choose one, kill the poor guy and take the key. Notice the Diary on the desk and a Power to the People station. Afterwards use the control panel in the middle of the room. You will have to fight a couple of enemies (two Alphas). Once you deal with the problem, backtrack following the arrow. On your way you will encounter three more Alphas.
AUDIO DIARY: [Magic Sauce] - Warden Nigel Weir
09 - Go down to the dark room and then even lower. Search the holes to find the [Elemental Vampire] Tonic.
10 - Search the safe and take the Audio Diary. A little closer to the main hall (with the boat) you should get attack by an Alpha.
AUDIO DIARY: [Out With the Old...] - Warden Nigel Weir
It looks like Eleanor will need help of the Little Sisters. Head out on a rescue mission. The order in which you do it doesn't matter really, you just have to travel through the whole map. Let's begin from the western part.
11 - Go into the corridor in front of the turret.
12 - Fight with a couple minor enemies and take care of the camera. Search the cells, you'll find a Diary in the last one.
AUDIO DIARY: [Such Freedom] - Wilson
Many of the patients that you will come across here won't be willing to fight. A little further you'll come across a Houdini Splicer and lots of bodies, waiting to be searched.
13 - Press the button to open the bars. Tame the turret, collect the Audio Diary and use the Power to the People station. Afterwards, go upstairs.
AUDIO DIARY: [My Prison] - Warden Nigel Weir
14 - Hack the cameras and search the area to find two Diaries and a safe (under the counter).
AUDIO DIARY: [They Feel Pain] - Dr. Edward Grimes
AUDIO DIARY: [Alleviating Pain] - Dr. Edward Grimes
15 - Once you reach the Pediatric Ward, the fight will begin. Besides normal enemies, you will have to face two Alphas. After the fun's over, find the bell (by the entrance to the room with the Sisters) and ring it. Go back to the Docking Bay, where an Alpha should be waiting for you.
16 - Go into the corridor leading north.
17 - Collect a Diary from the body lying by the window.
AUDIO DIARY: [Legs, Mouths, Arms, and Eyes] - Harold Darby
Take a closer look at the painting hanging from the walls and count the brown legs, red lips, blue hands and green eyes in this exact order. Input the received code (4146) and open the locked door to discover a room with items and a safe inside.
18 - Look out for the camera and collect the Diary hanging from the side of the locker.
AUDIO DIARY: [A Simple Question] - Dr. Edward Grimes
19 - You'll find an Audio Diary in the room at the right end of the corridor.
AUDIO DIARY: [Destructive Learning] - Eleanor Lamb
Before you pay a visit to the next Pediatric Ward, check the left side of the corridor to find another Diary. Nearby there's a door with a code lock which you can hack. The hack itself isn't easy (a Hack Dart can make things easier), but inside you'll find some ammo inside. Take the stairs down.
AUDIO DIARY: [Sacrifices] - Augustus Sinclair
20 - Splicer, Alpha and also a Diary. In fact it's the last Diary you will find in the game.
AUDIO DIARY: [A Stratagem for Sinclair] - Andrew Ryan
21 - Once you get near the turret, an Alpha will attack. Afterwards a group of Splicer will jump down from the balcony upstairs, followed by the appearance of a Brute and another Alpha. After you've dealt with them, go ring the bell. Return to the Docking Bay.
22 - Before you approach the window, place mini turrets, traps and whatever you have in your inventory in the main hall, as in a moment you will have to survive the last fight in the game. Once you approach the window, Eleanor will disappear and you won't be able to call her throughout a certain part of the fight. You'll be attacked from both sides by Alphas, Houdini type and normal Splicers and also by a group of Brutes. Around the moment the last ones appear, you'll be once more able to call Eleanor. Once she gives you the sign - go upstairs.
23 - During the chaotic fight, you'll have to flip a switch. The last thing you'll need to do is destroying two wide pipes on both sides. The enemies won't give up easily, so quickly take care of the glowing parts.
24 - Once the room gets flooded, head to the lift. Now you can sit back and enjoy the ending of this exceptional game... At least one of the possible endings :)
