Water Caverns
Four to five guards will be in your immediate presence, kill
them, and try not to get touched. It's possible. Then just follow
the path the only way you can. You'll pass through two doors
before being able to veer off the beaten path. Go downstairs to
an area with two computers, a scientist or two, and some
ammo boxes. Blow these up the computers, and then the
boxes, for ammo. There is a pathway to another similar area;
you can take it or the stairs, both lead to the same place. There
are two main computer set-ups down there as well. Blow them
up, and objective A will be met. Make sure not to hit any
scientists.
You'll come to an opening. It leads to what seems like the
bottom of the entire cavern. There should be a guard or two,
so kill them off. A winding path leads in a spiral fashion along
the right side. Take this path (there aren't any other choices
anyway). Knock out about three military personnel along the
way. At the top is a guard and a door. From this door, a
handful of soldiers will emerge. Stand back, wait until they
show up, and then blow them the pieces. Make sure to stand
back and off to the side to stay unhit.
A circular cave with a central pillar and about three to four
guards and lots of ammo boxes are next. Nail all of these guys
and grab some ammo. Follow the path until you have a choice
of going down some stairs to your right or continue upstairs.
Go down the stairs and run straight down the hallway killing
everyone until you reach the end. Guards will shoot at you, so
turn back and go back up the stars you descended. Now run
along the top of the bridgeway blowing everyone away.
You'll reach an entrance, but don't go inside yet. Retrace your
steps to the very door that led you into this area in the first
place, and then walk down the stairs and do a 180 degree turn.
Follow this new path around until you get to a cavern with
lockers in it. The lockers will be on your right side. Blow up the
lockers. Behind them is a secret path to another cavern.
Lockers on the other side will block your path, and you'll have
to blast them, and unfortunately draw attention to your arrival.
You should have two ZMGs by now. Use them to blast
through the second set of lockers. Guards on the other side will
take note of all this racket, so be prepared when you arrive to
shoot at anything that moves. There are initially about three.
Two to three more join in from a stone staircase on the left.
Once the area is generally clear (note: if you stay in one place
too long, more soldiers will come), you'll see a big pump on the
left, surrounded by two computer consoles. Blow these
consoles up and the one to the left of the secret entrance, and
objective B will be met.
Walk up the stairs carefully. No one should be in sight. That
should worry you. To your right is an automatic machine gun
and two guards. Move out about a foot quickly to get the
guards' attention and then quickly move back down the stairs.
If done skillfully, the machine gun won't react. The guards will
come to you, and you'll kill them. When the coast is clear,
angle slightly to the right so that you can hit the big gun. Make
note of the locked door to the right for which you'll need a key
for it). Take the door to the left, instead. Now you have to
carefully clear the guards from the paths. Wipe them out and
you should pick up a few security cards along the way.
You will next approach an opening guarded by two soldiers
with sunglasses and berets. These guys have RC-P90s and
carry code cards B and C. You're near the heart now. Kill
them but don't enter the doors behind them.
You're about to enter the radio room. You must not make any
big explosions that could destroy the radio. Take a look
around real quickly and then pull out. There are a few guards
inside, one with a RC-P90 to your right, as well as a piece of
body armor on the crate. Go through the first door, open the
second and peek around. Kill any stray guards and back out.
Do this until you're sure no one is left but the RC-P90 guy on
your right. In the distance are the radio, scientists, and three
soldiers who stand right in front of explosive barrels. They can
easily shoot at you from the right, so shimmy to the far left wall
and turn around from where you came. The RC-P90 guy will
start shooting, and to need to take him down from where you
stand. Now, use the leaning technique to peg each of those
three soldiers near the radio. Use the site on the rifle, too.
Once the area is clear, go to the control room and radio
intelligence. After you've send your signal, put a timed bomb on
the explosive barrels, and another objective is met (Objective
C).
Now get out. Go back to the room with the strange blue door
you couldn't open. You should have picked up a key to open it
by now. Two guards will be waiting for you on the other side.
Kill them. Go through the next door on your left, the exit. Janus
will appear and say something like, "Too slow, eh, James?"
Then an automatic machine gun on the ceiling will start blasting
you. Kill it as fast as possible and enter that area because
visitors will appear behind you. Run through that tunnel, find the
elevator, and you're out.
