Press the button and enter the door to the right. Some pit drones emerge and attempt to hack you to pieces. Kill these pit drones (there are several of them) and explore the garage. A crate in the back of the truck contains a trip mine. Grab the armor pickup on the left side of the room and break the crates on the right side for a satchel charge and rocket launcher. Locate the steps here and follow them.

Climb down to the elevator below and into the passage on the right to locate the electric switch box.

Follow the tunnel to the lift and kill more pit drones. Break the crates here if you wish. You can speak with the scientist at the end, but he won't be much help. Approach the door overlooking the elevator shaft. Your goal is to find a way onto that electric wire, but you'll never survive the shock while the electricity remains on. Leap onto the ledges on the left and make your way down to the ground via the ladders. Once on the ground floor, enter the broken elevator and climb through the top vent (use the grate that's open as a ladder).

Locate the path into the hall; simply jump to it from the top of the elevator. Once inside the hall, take a left. Attempt to avoid the live wire hanging over the water. It'll be tough since the water is quite slippery. Break the crates so you have more maneuvering room. Once through, continue over the green crates and through a chain-link fence into a room marked Unit 2 Power. Press the "use" key at the power control to switch off the electricity. Return to the elevator shaft.

Climb up two ladders and face the wire, which is no longer conducting electricity. Leap to the wire and recall your rope training from boot camp. Ascend the wire by pressing the up directional key while looking upward. Get near the top and face the elevator positioned high up here. Swing on the rope; use the up and down directional keys while facing the elevator. At the height of your swing toward the elevator, press the jump key to let go and fall on top of the elevator. Fall into the dark elevator for some armor power-ups. Go back out by using the open grate. Enter the corridor and turn left (a locked door is to the right).
