|Part of||Episode 3|
Open the door in front of you, then kill everybody in the subsequent hallway. Find the only door in the hallway that has an Adolf Hitler's poster on both sides and open it. You'll come to a fork with enemies: you can take either path, you'll eventually come to a room with the gold key. Go back to the starting hallway and find the gold door. Mow down the final opposition and exit the map.
1. Your first secret is in the starting hallway, across from the starting door.
2. Your final secret is in the wooden room on the northern side of the map, more specifically behind the poster in the middle of the wall at the bottom of the room.
