Proceed through the darkness to the bank of analytical equipment. Gil instructs you to flip the two circuit breakers—located somewhere in the darkness—then he’ll give you further instructions.
Move to the right, past the Circus of Values machine, and down the stairs. The first circuit breaker is straight ahead, just a few steps in front of you. Circle around to the left, past the large metallic structure in the middle of the lab, and through the steamy darkness to the sound of the short-circuiting circuit breaker on the north side of the room. Flip this second switch and pick up the Audio Diary below it before returning to the central platform where Gil spoke to you moments earlier.
Press the Power Mains Switch on the master control panel. The lights come on, though faintly, and you’ll see a brief glimpse of Gil Alexander in the enormous tank in the center of the room.
Collect four Adam-infused Plants
The mutated, spliced-up Gil, known as Alex the Great, is hiding within a massive Sea Life Tank in the middle of the Plasmid Research Laboratory. You need to bring him out in the open to deal with him, but this can only be done by placing ADAM-infused plantlife into his holding tank. Collect enough of the plants to lure Gil out of hiding.
