SECRETS

1. In the building to the North-East of the map, when you enter the corridor to the steps taking you to the landing above, a door opens behind you. Enter the small chamber and shoot the wall to the left to open a door leading to the secret area. [The door texture is slightly misaligned.]

2. In the building to the South-East of the map, when you enter the corridor after the steps shoot the wall to the left to open a door leading to the secret area. [The door texture is slightly different than the surrounding wall.]

3. In the same building, walk on the ledge around to the back of the building. Look for a slightly recessed section of wall with misaligned texturing. Press to open the door leading to the secret area.

4. In the building to the North-West of the map, when you enter the room at the top of the steps you'll see a section of wall in the middle of the room with an arrow-shaped gap. Run through and down the steps, through the arched doorway, and to the room at the right. A door will have opened temporarily, exposing the secret area.
