[8.3]. Mission 3 - Chicago: Stealth (2)

Retrieve drop point equipment: Walk to the end of the ally and take down the first guard with your fists. Peek around the corner and use a headshot (a shot that lands on the enemy's head, usually an instant kill) to eliminate the next guard. Go down the stairs and through the doorway. Quietly take out the guard next to the taxi, then the guard to the 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; 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.

Create vehicular diversion: Return to where the limo was, and continue to an opening in the fence leading to a sewer. Clear the sewer of guards. Exit the sewer the way you came in and go right to the taxi. Use the Reprogrammer on the taxi. Wait for the taxi to crash, creating a diversion.

Prepare escape route: Go to the right of the exploded taxi and eliminate the guards. Proceed to the top of the stairs and place a Remote Mine on the concrete door, but do not detonate it yet.

Gain entry to G5 building: Enter the red hallway across from the taxi. In the next room, knock out the two civilians. Push a trash bin next to the barrels in the corner, then shoot the barrels to cause an explosion and retrieve the BombSpy from the ground. Backtrack to the hallway and use the Bombspy to look into the next hallway. Activate the Bombspy in the area with the guards to eliminate them. Walk to where you activated the Bombspy. Exit this area and go straight ahead into the room across from the storm drain. Enter the giant elevator to complete the mission.
