----------------------------
At the first set of white double doors, stay back and wait for
the guard to pass the pillar in the middle moving to the right. Sneak out to
the right, along the wall, and back to where you started outside the double
doors. Now go along the right wall and then over where the guard is, wait at
the end of his patrol in the darkness, while staying in the hallway. When he
turns his back, sneak behind him and into the doorway to the left of the
cubical room, but crouch in the corner by the doorway so the patrolling guard
can't see you when he passes to the left. When the patrolling guard passes
you, go behind him and down to the metal detectors where the security guard is.
Stand outside his window to the left and jump, he will go investigate, jump
through the window following right behind him. Go out the door and when he
turns to the right, into the metal detectors, you keep crouching along
the wall
of elevators at full speed, keep going and then turn down the hallway. You
should of finished this before the guard comes down the two stairs. Sneak by
the worker when he turns away and go down the hallway. At the end to the left,
go inside the opening down some steps to the armored camera, and a keypad door.
Stay at the bottom edge of the stairs to the right, and you can access the
keypad from there, wait for the armored camera to turn left and go through the
door.
Wait in the dark area right in front of the window, once the man is off the
phone, he moves over to the soda machine, sneak behind him and into the door
where a turret gun is. Then go into the
elevator and go up.
