Display level: Displace Mercenary outfit:
Go to floor 3. To learn what door has the costume, look through the optic cable. Once you see the green package you will have to enter the room. The keypad lock code to this door is "5800".

Hokkaido level: Thermal Suit outfit:
Before you try to find the costume, locate the wrench that is laying on the ground. Then, proceed through the level until you reach the man who is shooting at from the top of the building. Once you kill him, get to where he was. Then, run across the rooftop to the vent. Exit the room you fall into. If done correct in the top left corner of the room the icon "Bash Door" should appear. Bash the door and the costume will be there.

Kokubo Sosho level: Shadownet Agent outfit:
Once you go down to the elevator shaft Sam considers the Descent to Hell. There will be lasers at the bottom. Once you are down there find a ladder to get back up. Once you climb it, you will end up in a small room with lasers. The costume is somewhere in the back corner.

Lighthouse level: Camouflage Sam outfit:
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.

Machi Akko level: Argus Mercenary outfit:
You will reach a hallway after you fall out of a vent. There are three rooms in this hallway that require the lock pick to enter. In the third one will be a closet, just like the other ones. However this closet cannot be opened yet. Keep this room in mind. Once you reach the bar, go on stage and use the microphone. Sam will say something stupid. 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.

Cameras:
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.
