== F. ARCADIA [c03s06] ========================================================

In this level you'll start picking up a lot of random junk for use in U-Invent
machines. There's not much to do with it, just pick up everything you find and
wait to get to a U-Invent, where you can see what you've made with everything
you've collected so far.

Head down the hallway, past the Vita-Chamber, and up the stairs to the door,
jumping over/crawling under debris as needed. Bash the lock off the door, and
head on through. Wow, trees! Been a while since you've seen those. Turn left
and head across the bridge - on the north wall you'll find several doors. Near
the leftmost door is a park bench with an audio-diary (Seeing Ghosts) next to
it. You'll hear someone shouting for help in the background - ignore him for 
now, it's just another splicer.

OPTIONAL: Thanks to everyone who e-mailed me with this info - directly across 
from the entrance is a door with two torches on either side, one lit and one 
not. Use your incinerate plasmid on the torch that's not lit to open the door. 
Inside you'll find a TON of ammo and other loot.

OPTIONAL: The two leftmost doors are marked Arcadia Glens, head through one of
them. This leads to an antechamber area before the entrance to Arcadia Glens,
which is unfortunately completely blocked off by debris. There is, however, a
ghost cutscene and two audio-diaries - next to the park bench on the left side
of the room (Big Night Out), and next to a chair and knocked over table on the
right side of the room (Mass Producing ADAM). Head back out when you've got
them.

Head through the rightmost door, marked Rapture Metro/Arcadia Glens. This is
where the shouting you heard earlier is coming from, from a Houdini splicer.
This is the first time you will have encountered these guys - they are fairly
nasty, since they can teleport, turn invisible, and shoot fire. Grab some
photos when he's visible, and then just follow the blurry area around and shoot
him when you can.

OPTIONAL: Going straight ahead from the entrance will take you to a small
flooded area with some loot. Head back like you're going towards the entrance,
but turn left instead, following the sign to the Metro. Go past the stairs and
you'll find another room with some more loot (make sure you check out the table
with the mask on it).

The splicer will lead you up the stairs to the right of the entrance, up to a
gardening supplies storage area. Finish him off, and then check out the table
to the right - there's an audio-diary (Arcadia Closed) with a Gene Bank next to
it. 

OPTIONAL: Check the crawlspace directly across from the audio-diary for loot.
You should see "Who is Atlas?" posters inside (Storyline hint? Maybe? MAYBE???)

OPTIONAL: Head into the other crawlspace on the south side of the room for
some more loot. Going in here will trigger a splicer spawn in the storage room
behind you, so be careful when you come out.

Head through the door marked "Rapture Metro". This will take you to a balcony
above the Arcadia Glens antechamber area where you found the audio-diaries
earlier. There'll be a splicer on a balcony across the open space shooting at
you, and another one on the balcony you're on. Kill them both. You can use your
telekinesis plasmid to grab some spare ammo from the balcony across the open
space, or to loot the corpses over there.

Continue through the door at the end of the balcony. You'll enter a room with
several splicers and a turret. Move forward into the room so you're out of the
line of sight of the turret, kill the splicers, and then zap and hack the
turret. Stock up at the vending machine if you need anything.

OPTIONAL: To the left of the door where you entered is a shorted-out door. Hit
the switch with electrobolt and head in to grab some loot. Head back out.

OPTIONAL: Go through the door marked "Employees Only", in the SW corner of the
room down a little hall by the stairs. You'll see a splicer walk around the
corner and get pwned by one of the electric crossbow trapwires (you'll get to
use these yourself later on). Take note of what happens to him - make sure it
doesn't happen to you. Jump over or crawl under the wires to grab the loot in
this room. You can also use your telekinesis power to throw objects through the
wire, which will set them off. Way in the back is another crawlspace protected
by a trapwire - head in to find a bunch of ammo and a safe. Another crawlspace
door in the back takes you out to the main room.

Head down the stairs down the hallway in the SW corner of the room, kill the 
splicer, and keep moving forwards, following the signs towards the Rapture 
Metro. Turning the corner, you'll find you are at the entrance to Arcadia 
Glens, only on the right side of the barricade this time. Head through the door
and enter the Glens.

OPTIONAL: Turn right as you enter. Ahead of you will be your first U-Invent
machine. Walk up and use your junk to make some nice loot for yourself.

OPTIONAL: Head down the stairs by the U-Invent machine, into the flooded lower
concourse. Turning left you'll find a corpse and a small alcove protected by a
trapwire that both have some crafting junk on them. Head back up. You can
continue on down the concourse now if you want, but we'll be heading back later
anyway. 

Head left from the entrance to Arcadia Glens. You'll come to a small area with
a Gatherer's Garden machine and, conveniently, a big daddy/little sister. Take
out the big daddy (you're literally right next to a Vita-Chamber, so it 
shouldn't be too difficult) and harvest/rescue the little sister.

OPTIONAL: Head in to the Waterfall Grotto through the doors by the 
Vita-Chamber. We'll be coming back here later, but no harm in clearing it out
now. In the left corner is a U-Invent machine and a corpse with some nice loot.
In the other corner, by the sign, is a staircase down. There's a park bench by
the stairs with an audio-diary (The Market is Patient) sitting on it. Head down
the stairs. This room unfortunately has a rather difficult security system
arrangement, so we're going to take it out now to make things easier when we
come back. You should see a splicer in the flooded area at the bottom of the
room. Kill her, and then jump down and run across to the stairs at the other
side of the room (you'll have two turrets shooting at you). Turn left at the
top of the stairs - you'll see a security camera. Zap and hack it, then turn
left and zap and hack the first turret. It will start shooting at the second
turret down in the flooded area, which should buy you some time to get down
there and zap and hack it. There's an audio-diary (Offer a Better Product) on
a brick near the second turret - pick it up. In the SE corner of the flooded
area is a passageway to another room. Head in, and zap and hack the 
flamethrower turret you'll find there. There's also a Gene Bank machine and
some loot. Head back out, and pick up an audio-diary (Early Tests Promising) on
a crate next to the water wheel. Finally, head back up the stairs near where
the security camera was. Zap the sparking door switch to reveal another room
with some loot and another audio-diary (Heroes and Criminals). Follow the quest
arrow back out to the hallway.

OPTIONAL: Head down the stairs in the SW corner by the Vita-Chamber. This takes
you back down to the lower concourse, where we were earlier. There's a Houdini
splicer down here you need to kill. At the corner up ahead is another staircase
where you can get back up to the main hallway, close to the Tree Farm/Rolling 
Hills entrances. Watch out for the camera. For now continue on down the lower 
concourse. You'll come to an open area with a vending machine - stock up on 
film and whatever else you need. In the SW corner is a flooded storage room 
with a Houdini splicer, some loot, and U-Invent and Gene Bank machines. In the 
NE corner is a crawlspace door which leads to a small room with some loot and a
safe. Next to the crawlspace door is a door which leads back to the main 
hallway, near the Tree Farm/Rolling Hills entrances. Again, watch out for the 
camera.

Head through the door into the Rolling Hills. There'll be a splicer and an RPG
turret waiting for you - zap and hack the turret and let it kill the splicer.
You can hop up the waterfall to a ledge with some extra loot. If you look at
the map, you'll see that there should be a passageway to another area - it's
blocked now, but don't worry, it will open up soon. There should also be a big
daddy/little sister patrolling through this area - drag it back to where you
hacked the turret and take it out. Near the stairs heading out of the area
there's a park bench with an audio-diary (Shouldn't Have Come) next to it.

Head down the stairs and keep following the quest arrow towards the Rapture
Metro. Whoops, this triggers an event - Ryan's trying to kill the forest. Atlas
asks you to find Julie Langford, the lady who grew the forest, and ask for her
help to repair it. Thankfully you're right next to her office. Head through the
Research Laboratories archway and zap/hack the camera (it'll come in handy
later on). If you turn left and go down the hall there's an Ammo Bandito if you
need to stock. Head through into the offices - you'll get a video transmission
from Langford at the entrance. She wants you to head back to Waterfall Grotto
to grab a sample of Rosa Gallica. Follow the quest arrow back out to the hills,
but watch out for the splicer who will charge you. Try to drag them back to
where you hacked the security camera to trigger an alarm. Keep following the
quest arrow back to Waterfall Grotto.

OPTIONAL: When you get to the stairs heading up in the lower hills you'll see a
Houdini splicer standing by the entrance to a cave which was previously
blocked. Follow him in and take him out. Right by the entrance is an
audio-diary (The Saturnine). Search the room for other loot.

OPTIONAL: Once you go up the stairs, the other area that was blocked off
earlier has opened up as well. It's another Saturnine cave with a Houdini
inside. Kill it and search the room to find some crafting junk.

Once you get to the Waterfall Grotto for the second time you'll see a bunch of
splicers standing over the corpse of a Houdini. Kill them all - there's a free
gene tonic (Security Evasion) by the body. Head down to the lower part of the
grotto, by the water wheel - the roses are growing on a bush right by the
wheel. Picking one up will trigger a spawn of splicers coming down the stairs
behind you. If you hacked this room's security system earlier they'll take care
of them no sweat.

Follow your quest arrow back all the way back down to Julie Langford's office.
She'll ask you to send the rose through the pneumo, and then opens up the door
for you, letting you into her office. Immediately inside you'll find a free 
gene tonic (Hacking Expert) on the desk and an audio-diary (What Won't They
Steal) on the floor. Turn right and head on up to Langford's office. She'll
turn off her security system so it doesn't attack you. Grab an audio-diary
(Teaching an Old Hound) off a desk in the next room. There's a vending machine,
a U-Invent, and a Gene Bank in the room after that. Follow the quest arrow to
the tunnel, which takes you up to Langford's office. She unfortunately meets a
gruesome end as soon as you get there - note the code she paints for you on the
window as she dies (9-4-5-7). Wait for the gas to clear and then head into the
room through the side door. Grab the chemical launcher (new weapon) off her
desk, and search her body for an audio-diary (The Lazarus Vector).

Use the code on the safe in the back wall, behind the painting - it contains
another audio-diary (Lazarus Vector Formula) and the key to get into the
Farmer's Market area, which is where we're headed next. The diary gives you a
shopping list of stuff you need to get to create the Lazarus vector, which will
bring all the trees back to life. Once you've collected it all, you need to go
to a U-Invent machine to craft the vector, and then bring it back to Langford's
office to release it into Arcadia. That's still a long way down the road, 
however. 

First for the chlorophyll - usually whenever I played through this part I had
already collected the chlorophyll I needed by the time I got the formula. One 
of the audio-diaries in Langford's office suggests that the Saturnine have been
stealing it, however, so if you still need more try killing splicers
(especially the Houdinis with the weird masks) and searching their caves in the
Rolling Hills.

The other two items (distilled water and bee enzymes) will take a little more
effort to get - we need to go to the market area of town to get them. Head back
out of Langford's office, but watch out, since there will be splicers and the
security system is also now active. Try to hack all of the security elements
you can instead of destroying them - you'll need them later on. Once you get 
back to the Rolling Hills you'll get a transmission from Atlas telling you to 
head to the market to look for the other ingredients. Exit the Rolling Hills 
where you entered and then immediately turn left to enter the Tree Farm (watch 
out for the security camera). There's an audio-diary (Arcadia and Oxygen) 
leaning against a crate just inside the entrance.

Head south down the wide hall and turn left at the end - there'll be
a weapon upgrade machine on the wall to your left as you turn the corner. Keep
following the quest arrow east. At the entrance to the Farmer's Market area
you'll find another Saturnine (Houdini) splicer with chlorophyll. Head through
the archways and pick up the audio-diary (Maternal Instinct) on the stairs.
Head on through past the sign, and you'll reach the bulkhead door leading to
the Farmer's Market. We're leaving the Arcadia level for now, but we'll be back
soon.
