Whistleblower | Walkthrough Homefront: The Revolution Guide

Once you begin the mission, go to the James's apartment. The building has a red door. After a conversation with James, you will have to search Sutherland's apartment.

Once you arrive to the place, you will see the view visible on the screenshot. Your task is to get to the top floor of the building, which has to be reached through fire stairs on the right side. While near them, you have to watch out for a camera, but you don't have to destroy it. All you have to do is to go underneath it and jump on a small bridge on the left. On the top, destroy the glass using the knife and go to the next room. You will find a safe under the desk, which contains Sutherland's documents.

Your next task will be an elimination of the colaborator. Go to the place shown on the map, and you should see a view from the screenshot. The task is to identify Sunderland using the camera in your mobile phone. You have to make a photo, and James will tell you if it's your target.

Instead of photographing every passerby, go to the place visible on the screenshot. Sunderland will be inside the building, you can reach it from the left side. Once you reach the place, make a photo and wait for a positive identification.

After a successful identification, wait until Sunderland comes to the place visible on the screenshot, go behind his back and make a silent execution. After the whole action, leave the yellow zone, and return to James to finish the mission.
