  between two vent blocks on the floor.
  Checkpoint C. Swing from the two ropes while being shot at by two guards. Go 
  to the front of the building with "Coronat Opus" on the side. Before going to 
  the top of the water tank next to a locked door, you can get a bag next to two 
  vent fans. Climb the fans' housing, then Wall Run over a camera to reach it.
  Checkpoint C. Enter the plaza, and go through a vent. Drop down, and you will
