When the Colonel comes by, grab him. Drag him
over to the retinal scanner near the other gate. Knock him out and hide his
body under the steps.

Head through the door and put your back to the wall. Follow it to the left to
see a camera above the door. When it turns, lean out and shoot it. If you
failed to hide the bodies well enough, here is where you will find out.
Anyway, equip the laser mic and head out the door. Run to the right side of
the bushes and stop at the first corner. Crouch down and laser mic the
conversation. When it ends, immediately run towards the building opposite the
one you exited. Climb up the grating on the building and into the open window

but when I go treu the door an alarm goes of what should I to do??
