Mission 10: Cordis Die
Intel Item 1
After you take out the drones with the missiles, you will be given the option to snipe or rappel with the President. Whichever you choose, you will end up rappelling down anyways, so once you do reach the level below and make your way up the left side. You will see a burned out car with flames still going there and the intel will be on the other side of it.
Intel Item 2
Right after you finish driving the truck and destroy the first CLAW that approaches, enter the lobby on the left side and you can find the intel on the counter in the center of the room.
Intel Item 3
Just up the street a little ways from the previous intel item--after you destroy the third CLAW-- you will enter the Downtown Plaza. Go through the door on the left side to enter it and then follow the stairs up to the second floor. When you reach the second floor, look to the right side and there will be a shirt vendor where the intel is sitting.
