[8.3]. Mission 3 - Chicago: Stealth

Retrieve drop point equipment: You start with your fists. Proceed to the end of the ally and take down the passing guard. Peek around the corner and use a headshot (a shot that lands on the enemy's head, usually an instant kill) on the next guard. Go left down the stairs and through the doorway. Quietly eliminate the guard by the taxi, then the guard to your right. Avoid the patrolling floating robot as it cannot be killed. Continue down the right side of the street to a hallway on the right and kill the guard inside. Proceed past the limo and turn right. At the end of the ally, drop into the storm drain, turn around, and go under the grates to find the equipment. This completes the first objective.

Create vehicular diversion: Return to where the limo was, continuing until you find an opening in the fence leading to a sewer. Clear the sewer of guards and exit the way you came. Go right to the taxi and use the Reprogrammer on it. After a short wait, the taxi will crash, creating a diversion and completing the second objective.

Gain entry to G5 building: Enter the red hallway across from the taxi. In the next room, knock out the two civilians. Move the trash bin next to the barrels in the corner and shoot the barrels to cause an explosion. Collect the BombSpy from the ground. Return to the hallway and use the Bombspy to scout the next hallway where the trash bin was. Activate the Bombspy in the area with guards to eliminate them. Proceed to where you detonated the Bombspy. To the right, kill the guards, then go to the top of the stairs and place a Remote Mine on the concrete door, but do not detonate it yet. Exit this area, go straight ahead, enter the room across from the storm drain, and use the giant elevator to complete the third and final objective.
