IV.  BANK OF ZURICH (3 Secrets)
************************************************************************

If I had to pick which level is "Chock full O' gaurds", this is it, so if
you don't like the gaurd fights and creeping around, go ahead and mentally
prepare yourself now.

First thing you're going to do is talk to the gaurd at the main desk and
he'll point you through the door on the right.  Go through the two doors here
and you'll be in the "Atrium".  There is nothing to find on this level and 
the only door you can go through is the one in the center on the left side,
so just head there and go in.

Speaking to the gaurd here is useless unless you just want to hear him say
stuff that only borders on funny, so you can skip him and go to the gate and
use your newly aquired LASER ETCHED KEY to get in.  Once the gate is open, 
there is an open room right in front of you to go in.  Don't bother exploring
the hallway, there is nothing there.

In this new room, you will again use the laser etched key to retrieve your 
box o' goodies, but, to your surprise, it gets there and THEN it decides
to let you know you need a password.  Then you have cutscenes telling you
about the symbol on your box of goodies and what numbers it represents and
the Fibonacci Sequence and 21 and 500 and 521 and blah blah blah, so its 
going to make you do math again, but at least its math you can do in your 
head because you only need a 4 digit number this time so:

     21+500=521 (this you know already), 500+521=1021

How about that.  A 4 digit number.  "1021" is your password, so enter it, and
the box o' goodies is yours.  Inside, you get the Cryptex and no clue how to
open it . . . .SWEEEEEEET!!   not.

Examine the box again and you will find that there is a tiny hole in the 
smaller box that contained the Cryptex, but you need something to poke into
the hole.  Well, of all things, suddenly you can examine the desk on the left
side of this room.  Open the drawer and inside you'll get a paper clip.  Of
course Sophie will tell you how very perfect that is, so go and use it on 
the little hole in the Cryptex case.  You get a lovely little poem that if
you know anything at all about "The Da Vinci Code" (even if you've only seen
commercials, or it could be you are over 30 years old and you are a Monty 
Python fan), you know boils down to one word:  "GRAIL"  Go into your 
inventory and chose the Cryptex and "use" it.  Enter the word "GRAIL" and 
you're on your way.  The bank manager comes in and very kindly tells you to
get the hell out and he's going to help you do it without getting busted.

After the cutscene, head out the way you came in, but when you get back to
the "Atrium", head to the left and around to the elevators.  Use the security
card the bank manager just gave you on the elevator.  A cutscene lets you
know that this is the last friendly gaurd you're gonna see on this level,
because this guy is too stupid to know he's supposed to be pissed at you yet.

When you're in the elevator, you're told that you're screwed and you need to
get out of there before the elevator opens, so lift Sophie through the door
in the top of the elevator and up you both go.  Once there, turn the crank 
you see on the wall to open the doors.

Head to the right out of the elevator.  There are two gaurds patrolling this
floor.  Go into the first set of doors you come to, which should put you in
a storage closet.  Look around in here and you'll find a large bandage, and
you should see the eerie glow of one of the secret items, so, of course, 
search the shelves to find the **MARS SPHERE**.  Exit the closet.

At this point, what you do with the gaurds is up to you.  What you want to do
is continue along this side of the Atrium to the doors further down the hall.
If you can get there and into the Admin Office without messing with the 
gaurds, good for you, if not, try to only have to get rid of one of them.
Enter the Admin Office.

In here, there are two more gaurds.  Sophie will not follow you in here, so
you are on your own for fighting, so just don't fight.  Immediately crouch
and look straight ahead and a gaurd will pass from right to left.  Sneak up
behind him and stealth attack him and knock him cold.  Move up a little 
further and look to your right around the cubicles and you'll see another 
gaurd on patrol.  If you crept up correctly, you should be able to sneak up
on him and do the same thing you did to the first gaurd in here.  If not, 
just fight him and take him out.  You are now free to explore and do your
thing on your own time in here.

First thing will do is take care of one of the two hardest secrets in the
game to find.  If you go to the door you came into this room, and turn 
around and look into the room just as you did when you came in, you need to
go all the way to the back of the room to the furthest cubicle on the RIGHT.
Go in the cubicle and you'll get the "examine" cue.  Examine the shelf here
and you'll get **DA VINCI'S BALLISTA**.  (If you choose to find this cubicle
by looking at the map on the wall to either side of the door, it will be the 
cubicle in the lower right corner.)

Now you have to go to the Administrator's office.  As you came in, its on the
left side near the back, and you have to walk to a smaller office with about
6 cubicles in it to get to the Admin Office.  (Does this mean the
Administrator has 7 secretaries??  This guy can DELEGATE!!)  Once in the 
Admin office, go to the desk and insert the security card after the bank
manager gives you the code.  Enter the code "867530" and it will be wrong,

     (TRIVIA NOTE:  For those of you who might be fan's of 80's music, note
      that this passcode is the first 6 digits of the song "867-5309 (Jenny)"
      that Tommy Tutone topped the charts with in 1981.  I have yet to 
      confirm if this was on purpose, or if its a freaky coincidence.  Is my
      age showing?)
 
so the manager tells you to check out the Office Managers office.  As you 
stand, the Office Managers office is directly across the main cubicle room
from you,so head out and go across and enter the Office Manger's office.

Search the desk first.  There is a large bandage in the bottom left drawer
and a password in the middle right drawer.  When you're done with the desk,
turn around and examine the painting with the UV light.  Examine the 
fingerprints you find.  Now you can lift the painting and reveal the safe
that is hidden behind it.  Use the password you found in the drawer to open
the safe "728559".  Take the FILE CABINET KEY you find inside and leave that
office.

Go to the right and enter the file room at the end.  Go all the way to the 
back of the room to the last set of free standing file cabinets (IE:  Not the
ones against the wall) and find the set that allows you to "examine".  Unlock
the top drawer with the key you just obtained from the safe and get the 
password.  Go back to the Admin Office.

Put the security card back in the computer and enter the code that you found
in the file cabinet "260924".  Head out of here and back towards the door you
came in here from and find the Security Card Reader in that corner.  Use the
security card and move to the stairwell.  When you get to the bottom, you'll
go through another door and end up on the lower floor of the "Atrium".

There are gaurds here, but if you immediately crouch and head to the left,
you'll end up near a door that says it is "Deposits and Servers" or something
to that effect.  Enter that door and go down a long hallway that has nothing 
in it but doors you can't open until the last door on the left.  Go through
that door, down a little hallway past an unmanned security desk and through 
another door.  You end up in a small break room.  Walk through it and you'll
be in a big "privacy cubicle" room.  Walk all the way to the far side of this
room and peek to your left and you'll see the two gaurds in this room.  It's 
up to you how you handle those two because I knocked them both out when I was
searching for secrets, but it is possible to get through the room without the
gaurds even knowing you're there.

As you come in this room, the place you want to be is the other corner of
this room directly to your left (there is a security card reader and another
door in this corner).  There is a privacy room you can enter, closest to the
security card reader, however the secret you want is in the privacy room
directly BEHIND it.  In other words, check the two privacy rooms closest to 
the card reader, you'll see the glowing symbol on the wall when you go in.
Get the **IRON COIN**.

On the same wall as the door by the card reader, there is an air vent.  Go 
there and you will be prompted to shove Sophie through it.  Do so.

You are now in a small server room and a gaurd will walk up between the 
servers and turn his back to you.  Creep up on him and take him out with a 
stealth attack.  Go to the left from here and you'll find a set of doors and 
an office with no door.  Creep into the office because there is a gaurd 
standing there with his back to you.  Take him out with a stealth attack. 
You can now upgrade your security card once again at the computer found in
this office.  Just stick it in . . . no password or puzzle necessary.

Go back out of this office and through the doors right beside it.  Go down
the short hallway outside the card upgrade office and open the door at the
other end with the security card.  Langdon will meet you there and you'll be
back in the "privacy cubicle" room.  Leave here the way you came in and go 
back to the "Atrium".

When you're back in the Atrium, there are two gaurds here, but there is no 
need to even mess with them.  Simply crouch, turn to the right and follow the
wall around to the loading dock door.  You've got time and space here, so 
listen to the gaurds conversation for a giggle if you want.  If not, go ahead
and enter the loading dock area.

You'll be in a sitting room with a security card reader and a caged off door.
Use your upgraded card in the card reader and the cage will raise.  Creep
through the doorway quick enough and there will be a gaurd walking away
from you that you can sneak up on and take out with a stealth attack.  As 
you now stand, you should now see a gaurd just standing there and looking
to your left.  Believe it or not, you can crouch and sneak up beside and then
behind him and take him out with a stealth attack (the guys gotta be BLIND!).
There is a small bandage in the closet behind that gaurd.  Now look down 
where that gaurd was looking and you'll see a gaurd waaaaaaay down on the 
other end.  He does pace back and forth, so I suppose you COULD sneak up on
him, but its quicker just to run up, fight him and knock him out.

The arrow on the floor points you out the door, so follow it.  Go to the end
of that hall, use the Vehicle Key on the doors and the level is over.
