Manhunt/Key Personnel

After entering the Starkweather Estate through one of the basements, Cerberus shuts off power to the elevator, and has the key held by the leader. There are three steps in this scene:


 * 1) Turn on the elevator. The power switch is located on the other side of the mansion, across the foyer and down the spiral staircase.
 * 2) Retrieve the key from Cerberus leader.
 * 3) Reach the elevator on the second floor.

East wing
Before entering the corridor, you may want to head down stairs to retrieve a sickle on the shelf. This allows you to make executions without alerting the patrolling guards, although it is not essential to complete the level.

When you exit to the corridor, you see a camera to the right. This camera will attract a Cerberus guard if it spots you, or if it is shot from the wall.

Avoiding the camera requires heading to the left, where you should reach the room with one Cerberus agent on the lower floor looking away from you, who can be killed silently. Ascend the stairs, and head right, where you see a second Cerberus guard on the balcony, also facing away. Head down the stairs on the right.

When you reach the main corridor, you can silently kill the patrolling guard by attracting him to the stairs. The corridor ahead has a second camera, which may be evaded by going through the rooms on the left. The first room is empty, but there are two Cerberus guards in the next room. You can climb one of the stairs to the left or right, and lure one of them for an easier kill. The other should fall just as easily.

In the corridor, there is one more Cerberus agent, who hides behind cover on the right, and will most likely spot you upon leaving the corridor.

There is a break room, and if you didn't cause an alert, the Cerberus Leader with his key will be in the side room. It may be better to intercept him when he heads to the second floor.

The corridor leads to the main foyer, but is covered by an unavoidable security camera. The first save point is in the foyer in the middle.

Elevator power
To reach the elevator power switch, head to the other side of the foyer, and down the spiral staircase.

The basement has a total of four enemies in patrol, who tend to double back in their patrol routes. Enter the room on the opposite side of the stairs, and flip the switch to turn the elevator on. You can also find painkillers in one of the side rooms.

Elevator key
If you didn't alert the Cerberus Leader, he will be found in the break room near the foyer. It's dangerous to attack him here, but is possible to attack him when he makes the dash to the second floor.

If he was alerted and you didn't intercept him, he will head to the second floor, in the room for the Head of Security.

When you have the key and restored the power, you can head to the elevator on the second floor.
