Boot Camp:
After you complete the task of looking at the lights, walk right and go
through the door. On the shelf you will find a lock pick. You can use this to
pick the lock for the door just next to the entrance for covert ops. You will
find a keypad code, which can be used for the left hand door at the start
of the level. 

If you're lazy, the keypad code is 5656. Use the code on the left door.
Through this door are two rooms, Grimsdottir is in the second room. You
can talk to her, but of course, hitting her will get you fired.


Hiding
You cannot be seen when hiding in dark places. Shoot the lights to make it
dark, but make sure that there are no guards around. Do not stay in the
light too long. 


Escaping a room full of soldiers
Take a sticky camera or smoke grenades and throw it near where the 
most guards are located. For the sticky camera, a control bar that tells 
you how to make a noise or use smoke will appear at the bottom of the 
screen. Throw the smoke grenade and the smoke should knock out some 
guards. When the smoke appears from the grenade(s), it is your chance 
to run for it . 


Knock out an enemy
To knock out an enemy without killing him, equip the sticky camera and 
shoot it at his head. Aim slightly above the head to compensate for 
gravity. After he is down, pick up the sticky camera and use it again. 


Defense Ministry: Getting to the South Hall/Wing
After interrogating the driver and heading back upstairs, save at the 
checkpoint and view the intermission sequence of the window in the 
courtyard opening. Walk out on the balcony and turn left. Jump on the rain 
gutter on the wall. Move along the gutter towards the open window. If an 
alarm goes off, you have not properly hidden your dead bodies. Move 
back through the level and throw all your dead bodies into dark corners. 


Defense Ministry: Nikoladze's Office
Once you rappel through the glass window and kill the guard, access the 
computer in the far right corner of the level first. Then, access the main 
(Nikoladze's) computer closest to the window. Immediately run back to 
the window and drop out, but stay near to the ledge so that you will grab 
hold of it and hang out with the window. Guards will enter and search the 
office. They will not see you if you remain hanging out the window. They 
will clear the room, then leave. You can now access the computer again 
(as instructed by HQ). Then, proceed with caution when reaching your 
extraction point. 


Luring your enemy
To do this, find a can or glass bottle to pick up. Once obtained, move to a 
location, preferably dark. While hidden, throw the can or bottle to an open 
area with an enemy nearby. When thrown, the enemy will wonder what 
happened and walk towards that location. After you have drawn him out, 
you can take him out for an easy kill.


Extra Equipment Cia Level
Right after you have knocked out Mitchell turn around. Go to the last door 
in the hall. It will be marked UFO Sightings Office. Use your lock pick and 
unlock it. Go to the computer and get the data stick. It will be encrypted 
but, you can see the numbers 020781. Go to the keypad, type it in. Inside 
on the table to the right there is 2 sticky shockers and on the table to the 
left there is 5 reusable cameras. Take them and get the body. You may 
now proceed with the new equipment.

Gas Equipment Tips
Distraction Camera 
Whenever you see some enemies gathered, throw a Distraction Camera so that 
they will not notice it. After you have control over controlling the camera, 
continuously press the distracting whistle noise. The guards will come over, but if 
not all the guards are there that are in fairly close distance with the camera, then 
keep making the distracting noise. Once some of the guards are over there, 
release the gas. Sometimes the guards may just cough a few times, but not get 
knocked on conscious. 

Gas Grenade 
This is an equivalent of the gas that is in the Distraction Camera. However, this 
has a taller and wider gas range. Also, instead of spraying in one direction, this is 
like a gas cloud. Whenever you see a group of enemies, you will want to ricochet 
these off of a wall and get it so that it's positioned near the enemies. It will burst 
open and gas will fly out. Again, the enemies may not be knocked on conscious. 
Usually, depending on how close you throw it to the enemies, the enemies will 
immediately be alerted.


Thermal goggle keypad reading
The keypad is based on color it goes from Deep Blue, Blue, Light Green, Green, 
yellow, and orange-ISH for example if you looked on a keypad after someone and 
put in a code and see a dark blue at 5, light blue at 4, light green at 3, and orange-
ISH 2 than the code is 5-4-3-2.

Annoy Lambert:
When you begin the first level (Dili, Timor) you will start off in the water. Now just 
sit there, or run around in the water, but don’t progress through the level. After 15 
seconds after Lambert stops briefing you, he will ask you what you are doing. 15 
more seconds after you reply, he makes another comment. And another 15 
seconds left, he tells you to get moving because lives are at stake. Now you are 
free to continue your game.

All items and infinite ammo:
At the main menu press Up, Down, Left, Right, Right, Left, Down, Up.

Passenger Car:
On the train stage after you climb up from under the train you usually have to go 
around the outside of the train by way of the side door. But that can be very 
difficult since if people in the train see you the mission is over. An easier way is to 
turn off the lights by using the switch outside of the room where you climbed into 
the train from. Once th elights are off one passenger will come to investigate but if 
you hide behind the last row of seats you can knock him out easily. After that you 
can just walk through the car past the terrorists and all. (If you want to once you 
get to the other end of car you can lure the terrorists to you by whistling and then 
knocking them out. Just make sure they don't trip an alarm.

Stealth:
To move quieter, crouch down and walk slower. This will make your steps softer, 
and keep you undetected to a limit. To decrease your chances of being seen, 
shoot out the lights with your gun. Be careful, as if there is an enemy is under that 
light they may see you shooting it out.

Whistling:
To whistle, press Black. This will usually make a guard approach the sound. Note: 
Hide in a dark area and whistle, then jump the guard when he stops.

Defeating Norman Soth:
After you have climbed up the elevator cables and have gotten on top of the other 
elevator, crawl through the hole in the wall. Norman Soth and two other 
mercenaries are on the top pathways. While in the hole, there will be one guard on 
the top path, slightly to the right. You should be able to shoot him in the head. 
Then, a timer will start and you will have one minute to kill Norman Soth and his 
other mercenary. When you shoot the first mercenary, drop out of the hole onto 
the first pathway. The second mercenary will go to exactly where the you shot the 
first mercenary. Shoot the second mercenary in the head. Note: The second guard 
will be aiming at the hole, so he will not see you if you drop out of the hole. The 
last person to kill is Normon Soth. Start running down the pathway and turn left on 
the second to last walkway on the left. Look up and turn on your thermal vision. 
You will see Normon Soth. Get a clear shot and shoot him in the head. After that 
you must retrieve the smallpox box from the top pathway. If you are on the 
second to last pathway on the left, go up the ladder. There will be another ladder; 
use it to climb up. Drop off the ledge onto the pathway. Run down the middle 
pathway to find the smallpox box.

Prince Of Persia References:
On the mission when you are on the train, look in the second car where the guard 
is located. Knock him out then go behind the fenced door. Look down you will see 
a magazine featuring Prince Of Persia. Also, on the third level when you are in 
Paris on the train, at the beginning there will be a room with an engineer. Knock 
him out. On the floor of the room is a Prince Of Persia strategy guide.

Airport Alternate Route:
On the last stage (Los Angeles Airport) after you get through the parking garage 
you come to a room with a guard in a booth to your left and a female janitor right 
in front of you. In this room you have two options to advance. #1) The first option 
is to go through the guards booth by either luring him out and then running in 
before the door closes, or use the door code(its either 1387 or 1687). #2) The 
second and eaiser option is to go into the bathroom opposite the guard booth and 
climb through the vent in the wall this will take you to the same place as the other 
way and you won't have to deal with the guard.

Costume Change:
Beat the game on Hard difficulty mode and at the select game screen hold L + R, 
press black (2), white (2), Y, X, Y, X to unlock 2 different costumes for Sam.

Change Rate Of Fire In Multiplayer (Merc):
When playing as a merc, press and hold X to change your rate of fire (ROF) to 
Burst. To change it back to Auto, hold X again.

LAX - Room keycode:
If you want to get into the security room after the car park on the LAX level 
instead of using the vents in the toilet or distracting the guard to get him out and 
then finding out you have locked yourself in the room, just type 1387 on the 
keypad and your in!

Easier Aiming With Pistol:
To aim better with the pistol, press X to pull it out. The crosshair should appear 
normal. Then, press Up on the D-pad and the crosshair should become a laser 
sight. This makes it very easy to aim, since the laser sight is smaller and thinner 
than the normal crosshair. This allows fast kills and head shots. If you are in dark 
corners and have the laser sight on, the enemies will notice and attack you.
