Proceed through the door at the start and into a square-shaped corridor with an exit corridor to the north. When you start walking down the north corridor, you can hear a lift lower behind you. Run back into the square-shaped hallway and you can see that the door to the left of the opening to the north hall has opened. Behind it is a secret area with a backpack and a rocket launcher.
Immediately after passing through the teleporter in the crate room with six switches, turn around and open the wall with the lightning bolt on it. Inside is a soul sphere.
