Secret Area
During the training mission, after Lambert tells you to look for the lights, run to the left wall and wall jump to it. There will be a door. To open the door, enter 5656 on the key pad.
Nikoladze The Zombie
During the Presidental Palace level, after you snipe Nikoladze, go back to the library. Use the mini lift to go up and into the previous room. You will see Nikoladze standing there well and alive. He doesn't even notice you even if you stand in front of him.
CIA HQ
During the CIA level, you come to a point where you need to have three people walking away. To make this a WHOLE lot easier sneak up behind the patrolling guard AFTER the guys finish talking and knock him out. Then when you have to go through the door, the code is 7687.
Sticky Camera Tips
Once you acquire the SC-20, you can fire sticky cameras at the heads of enemies and knock them out without using your other weapons. You can retrive the camera after you fire it for a infinite ammo knock out weapon. If your camera is fire into a spot where you can not retrieve it, try firing on it to bounce it to a spot where you can pick it up.
