Intro

Start the Generator

The Vita Chamber

Proceed up the pink staircase ahead to find some coral blocking a pathway. Through the game recommends drilling through, it's better to melee through it instead to conserve fuel. Once past, crouch under the fallen pillar and continue into the Adonis Baths.

Adonis Baths

Cross to the other side of the room and enter Plasmid Therapies (you'll find some food and fuel just right of the entrance). As you clamber down the stairs inside the Plasma Therapies entrance, hang a left and get ready to drill a Splicer that emerges just after the corpse he throws.

Continue down the hall that the Splicer came from and interact with the Eve Dispenser behind the counter on the left. It's free, so go ahead and stock-up--you can hold up to 5. Now that you've loaded up on Eve, continue onward to the glowing vending machine in Plasmid Therapies just ahead.

Plasmid Therapies

Interact with the vending machine to acquire the Electro Bolt Plasmid. This power can be used to stun enemies with a shock. And since it's electricity, it's particularly potent for any enemies standing in water--simply aim anywhere at the pool and fire to give them a shock. Now before chasing after the little girl who got snatched up, you may want to explore the two adjacent rooms first for some goods. Now head back down the hall from the direction you cam and try out your Electro Bolt plasmid on the control panel next to the closed door--this will power it up, opening the way. Climb the stairs beyond back into Adonis Baths.

Adonis Baths

As you step foot into Adonis Baths, you'll notice a splicer just ahead, though there's another just out of sight on the right. Electro Bolt the one ahead at a distance and run up and melee him while he's stunned for a quick kill, then immediately turn right and shock and melee another. With both Splicers down, Electro Bolt the yellow panel along the right wall to power-on the generator.

Find Tenenbaum

With the generator enabled, a Quest Arrow will now appear at the top--this handy tool pops up every now and then to point you in the right direction. Follow it into the Luxury Resort on the other side of the room. Upon entering, hang a right into the bathroom to find some goodies and a locked stall that you can open for $5--it's well worth the cost as you'll find more money inside. Just beware a Splicer who'll be waiting for you in the hall on the right as you exit if you do choose to open it. Now follow the hall past the giant glass windows to a door that'll open on approach.

When the door opens, you'll eye two Splicers arguing in the pool of water ahead. Fire an electro bolt into the pool to shock both at once, then run up and melee them--just try to avoid standing in the water as you electro bolt it to avoid shocking yourself!

Enter the hall in the rear of the room and collect the Rivet Gun that's wedged between the floor and a door that can't quite shut. Once you have, the door will open, exposing a Splicer on the other side (there's another out of sight to his left). You may want to try out your new toy on him, then the girl that will follow. Once clear, there's a few things you should grab: the Eve from the chair on the left, the health pack in the hall just behind that chair, and some Rivets on the right. We also suggest climbing down the stairs on the right into Bathysphere Docking to find some goods, including Rivet Gun ammo! Just beware that a Splicer will be waiting for you back around the corner if you collect the goods there.

After loading up, climb the stairs leading into the Grand Foyer

Grand Foyer

Upon entering the Grand Foyer, a Big Sister will attack to keep you away from the girl. Now Big Sisters are tough, but luckily, you won't have to kill her completely--you just want to rough her up a bit so she goes crying home to mommy. Your basic plan of attack should be to use the Electro Bolt to stun her, allowing you to easily pop-off a few Rivet Gun shots while she's incapacitated. While doing so, we recommend circling the spherical statue near the room's entrance to shield yourself from her projectiles. Should you run out of Eve, forgo stunning her and just stick to shooting her (or if you run out of ammo, melee attacks will work as well). Before long, she'll let out a shriek and run out of the room, leaving you be.

After the Big Sister has departed, there are some good items to collect. Look for two First Aid Kits, one on a bar left of the staircase and the other on a table in the back, then grab the nearby Rivet Gun, among various other goods. After loading up, continue into the Banquet Hall to the left of the stairs.

Demeter's Banquet Hall

Grab the First Aid Kit from the chair ahead then follow the hall and drop into the next room. There a Big Sister will bust open the window, causing the current to sweep you into the ocean. The Quest Arrow will guide you through the murky depths--just keep an eye out for a corpse inside a small structure on the left that yields both a diary (noted below) and a First Aid Kit.

Continue into the airlock at the end and interact with the control panel to drain the room of water, completing the chapter.
