Agent A: A puzzle in disguise

Missable

You can do this in Chapter 4 and must be done before you turn the electric fence off. When you've gained Security Clearance Level 1 access, go through the first door with the panel that's blinking green (has a "1" on it). Once inside, you'll notice there are 5 miscolored bricks on the left wall. You need to press these bricks in the correct order to reveal a hidden staircase.

The order is as follows:

Top right
Middle right
Top left
Bottom left
Bottom right

Once the staircase is revealed, interact with it. You'll be met with a splitting path - a forward path and a right path. Take the path forward. You'll come to a communications tower surrounded by an electrical fence. Head over to the right side (you'll see a red box). Get close enough to the fence so you can touch it. When you're close, hold on to the fence by holding down and after about 10 seconds, Agent A will fry and get her new hairdo, unlocking the trophy.
