Tom Clancy's Splinter Cell Chaos Theory

You will reach a hallway after you fall out of a vent. There are three rooms in this hallway that require the lockpick to enter. In the third room will be a closet, just like the other ones; however this closet cannot be opened yet. Proceed to the bar, then go on stage and use the microphone. Sam will say something dumb. After he is done, turn around and look behind. A keycard should be somewhere. This keycard opens the previously inaccessible closet. Make your way back to this room and use the keycard to open the closet; the costume is inside the closet.

When you must steal millions of dollars using lockpick, go to the small vault left of the computer. Do the lockpick, and the costume will fall out.

First, find the wrench in the bathroom. The costume is in the room that is shaped like a "U", and has two cameras and four lasers. There is a keycard room in there. Once you enter the keycard room, in the right corner is a guard standing in the dark. Take him out and climb on the crate. Then, turn towards the next crate and select the option "Bash Door". The costume will be in there.

If you are on a mission where you cannot kill someone (for example, Manhattan Streets) take out your rifle from your back and equip it with a camera. Then, zoom in on a person's head. Shoot them with the camera. Make sure that it is the head or it will not knock the person out.

Finish sniping the man on the roof, then before you rappel down off the platform, stay on the platform. In the high right corner is the costume.

Successfully complete the game to unlock infinite ammunition, infinite items, and additional character skins.

Note: To equip an extra costume, go to the options screen, select "Extra", then tap "Enable Outfit.

On the Displace level where you can kill two men, one resets all alarms, but the other man sets them back to whatever number they were. The first is in the room with the computer and books on the desk. It is near the boiler room. Knock him out first and shoot him with the 5-7 pistol. The next man is in the room after you get out of the vent shaft. You can kill any enemy on a no killing mission if you do it this way. The third person that does something on this level is the one guarding Milan's office. He leaves blood stains resembling a gun. Note: These only work if you wear the National Guard costume, found on the ledge in Manhattan. The ones featuring alarms (the first and second men) only work on a random basis.

Go to floor 3. To learn what door has the costume, look through the optic cable. Once you see the green package, enter the room; the keypad lock code to the door is "5800".

The Displace suit is in the room next to the room where you have your last chance to save; the code is "5800". There are a total of nine suits.
