Mission 7: Numbers Intels
Intel Location #16: You will find this Intel right at the beginning of the level after you have interrogated Clarke. It will be on a desk in the back right corner behind you. You will need to grab this Intel fast before you die from the Nova 6 gas, which should not be a problem. Afterwards climb up the ladder that is located on the wall above the desk before the gas gets to you.

Intel Location #17: You will find this Intel lying on the ground in front of a shack garbage lying all around the ground. This will be just after you come to a point where you slide down the metal roofing and the game puts you into slow-motion allowing you to take out the enemies that appear.

Intel Location #18: You will find this Intel lying on the metal roofing with garbage as you continue to descend after Clarke gets shot in the head while you are trying to save him. This will also just be before the ending of the level where you slide down plywood.
