== J. HEPHAESTUS [c03s10] =====================================================

Hephaestus is the Greek god of the forge and blacksmiths - should give you a
hint what type of level this will be. Note that by this point in the game the
splicers are becoming significantly more difficult to kill - they do more
damage and have a LOT more hitpoints, especially the leadhead guys. Be careful.

Head up the stairs from the bathysphere - stop at the vending machine if you 
need anything. Go through the door and head down the tunnel. It doesn't matter 
which way you go, they both lead to the same place. When the two tunnels rejoin
each other you'll see a couple of splicers doing... something to a corpse. Kill
them and loot them.

Head through the door and down the stairs. You'll come to a larger room with 
some broken pipes. Directly ahead is a corpse with a chemical launcher, and
some splicers. Head up the stairs - there's a turret immediately behind the
wall you're facing as you enter the room. Zap it and hack it, and go over to
the vending machine by the broken pipe. The crate by the vending machine has an
audio-diary (Ryan Takes F Futuristics) and some other loot. Hit up the gene
bank in the SE corner of the room if you need to, and then head through the
door leading to the "Office of Andrew Ryan". 

As you enter the next room, turn left immediately - you'll see a vending
machine and a Vita-Chamber. On the ground between them is an audio-diary
(Scoping the Gate). Pick it up, and then grab the grenade launcher on the table
in the middle of the room. Continue southward, around the corner, and zap and
hack the security camera. There's a U-Invent machine here if you've got any
spare junk.

Head through the door underneath the security camera and down the hall. You'll
enter the antechamber to Ryan's office, where he keeps the corpses of people
who have crossed him in the past. Charming. Check out the door to Ryan's
office - it's sealed shut by some kind of electrical contraption. Search the 
corpses hanging on the walls. There are audio-diaries on the first corpse
hanging on the right (Stopping Ryan) and the third corpse hanging on the right
(Going to Heat Loss). The second diary contains a hint on how to get into the
office. It triggers an audio transmission from Ryan and updates your goals.
Ryan then sends in a bunch of splicers to attack you. Kill the splicers.

OPTIONAL: Head into the small side room on the south side of the trophy room.
On the desks ahead of you you'll see an audio-diary (A Man or a Parasite) and
a new gene tonic (Frozen Field 2). There's also a safe underneath the desk, and
some loot scattered around the room.

So now we need to go to Heat Loss Monitoring to try to find a way to break into
Ryan's office. Head through the other door on the south wall of the trophy room
(the one you didn't enter through) and continue down the hall. You'll come to
a flooded room with some splicers standing around a corpse of a big daddy. Use
your electrobolt plasmid on the water to electrocute them all. Loot the bodies
and head through the door to the Hephaestus Core at the end of the room. Go
down the tunnel and through the door taking you to the core.

You'll walk onto a balcony with a nice view of the entire core. Basically this
area has a bunch of walkways circling around the core, with a TON of splicers
wandering around. Be careful. You may also find a big daddy/little sister
patrolling around in this area.

Head through the doorway to your left, and kill the splicers. At the end of
this hall, near the Vita-Chamber, is an audio-diary (Fontaine's Legacy) and
some loot. (Is it just me, or does McDonagh sound EXACTLY like the GEICO
gecko?) Anyways, turn around and head down the stairs behind you. Turn around
at the bottom of the stairs, kill the splicers. In the alcove ahead of you is
a security camera and desk with an audio-diary (Running Short on R-34s) on it.
Zap and hack the camera and grab the diary. Continue on down the walkway,
you'll come to an area with a safe and some other loot. Turn back and head down
the stairs nearby. You'll come to the entrance to Heat Loss Monitoring. 

OPTIONAL: Turn around at the bottom of the stairs and follow the other
staircase (behind the big column thing) down. You'll come to an area with a 
spider splicer, a vending machine, and an audio-diary (Impossible Anywhere
Else). Kill the splicer, grab the diary, stock up, and head back up to the
Heat Loss Monitoring entrance.

In the alcove across from the entrance is a houdini splicer and a broken 
vending machine. You can still use the machine, but it will just spit out a 
live grenade, so make sure you jump back.

OPTIONAL: Head up the stairs directly ahead, past the alcove. There you'll find
a Power to the People machine, a Gatherer's Garden, and an audio-diary
(Assassin). If you continue down the next set of stairs it takes you to the
Geothermal Control area. Head back to Heat Loss Monitoring when you're ready.

Head through the Heat Loss Monitoring door, down the tunnel, and into the
entrance. Walk forward. The lights will go out and whoops, the corpses weren't
corpses (seems to be a recurring theme in this game). Keep moving towards the
door at the end of the hall - three of the bodies will jump up and attack you.
Kill them, and you'll get a taunting message from Ryan. Head on into Heat Loss
Monitoring.

Down the hall to your left is a vending machine. Down the hall to the right is
an audio-diary (Kyburz Door Code) and some loot. The diary tells you that the
code to get into Kyburz's office is Australia Day (which, in case you're
wondering, is January 26 - so the code is 0-1-2-6). Both halls meet up again
at a staircase heading down to lower Heat Loss Monitoring. There's also a big
daddy/little sister patrol route in this area.

Head down the stairs to the lower area - watch out for the corpse ahead of you,
he'll jump up and attack. Once you get down, head to the balcony over the
flooded area and watch the ghost cutscene. Head to the lower area on the west
side of the room. On the desk is an audio-diary (Getting a Break) and a free
gene tonic (Security Evasion 2). Grab the diary and your objectives will
update.

OPTIONAL: Head up to the Gene Bank in the raised area and slot in your Electric
Flesh tonic (if you have it). This will increase your electricity resistance
enough to let you hop across the electrified flooded area to the desk in the
far left corner. There's some ammo and an audio-diary (Genetic Arms Race) on
the desk.

Follow your quest arrow back up to the main core area, and then up the stairs
to the Workshops area. Go through the Workshops door, down the tunnel, and into
the main Workshops area. Kill any splicers you find. There may also be a big
daddy/little sister in this area.

OPTIONAL: Go down the hall to your right as you enter the Workshops. There'll
be a splicer and a turret. Kill the splicer, zap and hack the turret, and loot
the room. There's a bunch of stuff in here, including a U-Invent machine, some
ammo, and a safe. There's also a gigantic banner advertising Australia Day and
giving the date (another hint as to the code for Kyburz's office). Head back
out.

Hit up the bandito and the vending machine in the corner if you need anything,
and then head down the stairs next to them. When you turn the corner you'll be
at the entrance area to Kyburz's office - there'll be two turrets shooting at
you. Zap and hack them both. We'll skip Kyburz's office for now since we need
to head back there later anyway. 

OPTIONAL: Head into the little room by the foot of the stairs. There's a Gene
Bank machine, some loot, and an audio-diary (Device Almost Enabled). There's
also a crawlspace behind the desk with some loot in it.

OPTIONAL: If you look on the wall beneath the left turret you'll find a darkly
lit crawlspace door. Opening it will take you underneath the stairs, where
you can find some loot and an audio-diary (Market Maintenance Code). This gives
you the code for the area locked with a combination lock WAY back in the
Farmer's Market (it's 0-5-1-2).

Follow the quest arrow down the hall. You'll encounter a relatively undamaged
corpse - on it is an audio-dairy (The Dream). Way in the back of the room 
you'll find a bloodstained crawlspace door - open it and head on in. Inside 
you'll find some loot, a gene tonic (Damage Research), and an audio-diary 
(Assembling the Bomb). Great, another collection mission. The audio-diary gives
you a list of stuff we need to get to put together the EMP bomb. These items 
are scattered around the Hephaestus core area.

Nitroglycerine charge: Found in Kyburz's office (see below).
2 cans of ionic gel: scattered throughout the level. They look like tanks of
 chemicals for the chemical launcher, but will be glowing gold.
4 R-34 wire clusters: these are found on the corpses of big daddies. You can
 check the bodies of big daddies you've already killed to find them - they
 should be glowing gold.

Let's get the nitroglycerine charge first. Head back out down the hall, back to
Kyburz's office. You can get your first R-34 from the dead big daddy right 
outside the entrance to the crawlspace. Once you get to the office, input the 
code into the combination lock (0-1-2-6) and the door will open. Unfortunately,
the room is heavily booby-trapped with electric trapwires. Use your telekinesis
plasmid to pull the trapwires out of the wall and disarm them (thanks to
Nitramuse for this tip).

Head down to the desk in the lower area, and press the button on its side. The
door covering the nitroglycerine charge (on the south side of the room) will
open up. Unfortunately this also activates a turret back near the entrance. Zap
it and hack it, and then grab the nitroglycerine. There's also a weapon upgrade
machine right across from the nitroglycerine charge and an audio-diary (Great
Chain Moves Slowly) on the desk.

Head back out of the workshops - time to get your ionic gel. There's a lot of
the stuff scattered all over the Hephaestus core, but you can get the two you
need conveniently located right outside the Workshops. Head back through the
tunnel taking you back to the main Hephaestus core area. Turn left and head
down the stairs - there's an ionic gel behind the crates right at the foot of
the stairs. Head past Heat Loss Monitoring, up the stairs, past the Gatherer's
Garden, past the door to Geothermal Control and up the stairs, and you'll see
your second ionic gel sitting on a console on the left wall.

The last item you need is the R-34 wirings, which can only be found on the
corpses of big daddies. You're own your own here - retrace your steps and find
the corpses of the daddies you've already killed. They should be glowing gold
and each have an R-34 wiring on them. If you don't have enough, hunt big 
daddies until you do - they patrol through the main core area, the Heat Loss
Monitoring area, and the Workshops area.

Once you've got everything you need, follow your quest arrow back into the
workshops and down into the secret EMP bomb room. Use the EMP bomb three times
to install everything into it, and it will start humming and whirring. Pick it
up - you'll get a transmission from Atlas telling you that you need to attach
it to the core to destroy the power supply to the locks barring you from Ryan's
offices. Follow your quest arrow back out to the main Hephaestus core (watch
out for respawned splicers). Turn right once you get to the core, head down the
stairs, and keep going straight (following the walkway) until you get to the
entrance to Geothermal Control.

The room's entrance splits into two paths, both of which lead to doors to the
next room. Pick one, it doesn't matter (though there's a Gene Bank on the left
walkway if you need to use one), and head through. There are two turrets in
this room, one diretly down the hallway from each entrance. DON'T DESTROY THEM
- zap them and hack them. You're going to have to withstand an attack in this
room, and they will help you out a ton. Atlas explains what you have to do -
set up a defensive perimeter to beat off Ryan's goons, and then turn the valve
on the center ramp area to reroute the flow of magma. Here's your chance to
make use of some of the more specialized ammo and plasmids you've picked up
through the game. Use trapwires, proximity mines, and your cyclone trap plasmid
to block off the entrances. Note that you can find some extra mines in the
container right behind the valve, near the elevators. The turrets you hacked
will also help you out a ton.

When you're ready, start the event by turning the valve highlighted in gold.
Note that you have to hold down the A button to keep the valve turning, so
your security perimeter will be doing most of the fighting for you. Splicers
will start coming in through the entrances - let your security system kill
them, keep turning that valve. Eventually you'll turn it all the way and magma
will start pouring down. Atlas will tell you to head down the elevator to 
attach the bomb to the core - kill any splicers that got through your 
perimeter, get into the elevator, and press the button. When it gets to the
bottom, head forward down the walkway and through the door. On the floor in
front of you will be a corpse with an automatic hack tool and a gene tonic
(Shorten Alarms 2). Grab them and head through.

This will take you up to the core. Use the core lift control on the right side
of the walkway, and when you get to the top use the table thing to place the
bomb on the core. It'll activate, shutting down the core, and you'll get a
message from Atlas telling you to head back up to Ryan's office to shut down
his security. Unfortunately it will also trigger an alarm, so watch out for
bots on your way up. Follow the quest arrow out of the core area and back to
the entrance to Ryan's office. Watch out for stray splicers. When you get back
to the trophy room there'll be some splicers and security bots buzzing around.
Try to hack some of the bots for assistance, and kill the splicers. When the
room is clear, hit the switch by the security system blocking Ryan's door. The
door will open for you - head on in, and go through the bulkhead to Rapture
Control.
