Part 7

After defeating the initial Guardians, use the engine and steel bundle for cover and to conserve ammo. Health up and head for the elevator. Wait for Steve and Alyx to arrive and for Steve to complete his monologue before he powers up the generator.

Climb the ladder to the top of the elevator car and enter. Clear the pickaxe from the lever, ride the car down, wait for everyone to get in, then push the button and ride back up to the EP.

Follow the linear path, collecting supplies. Once Alyx lowers the SS, head out to retrieve the car from the bridge. The path is linear and slightly hidden.

You will hear rapid breathing before a drop. Your only path leads to a PST; clear the 2 crates from the busted wall and toss them to your right.

Pull the 2 crates blocking LOS on the XP and move them aside. GGP the chair away from the door, then move straight back to the wall and strafe right to the column. Allow the PST to bust the wall, exit the dark room, and turn toward you.

Strafe left as the PST prepares to toss a PS at you and continue through the dark room to the elevator in the room the PST busted out of. GGP the boards blocking access, then drop down to the floor below.

Locate and GGP the trapdoor of the next lift. Stand up as you drop into the elevator, then run out and hook left to and through the XP. Run around the door, drop off the platform to the stairs below, and pass through the next XP.

GGP the SCs for goodies as you drop off the ledge. If you miss one, hang close and GGP when the barnacle drops it. At the XP, crouch and turn left to face the door jamb. Press forward and tap strafe right to exit and slide along the wall to avoid barnacle tongues.

GGP the SC from the ceiling for ammo if needed. Approach the boarded-up XP square, turn to your 10:00, and GGP the boards. Run forward to the wall and along the ledge, bypassing barnacles.

In the next room with gas fire, kill the gas, run through the XP, and down the stairs. Halfway down, crouch and drop off right to the lower flight of stairs. Stand and sprint.

Do not rush the gate prematurely after popping the lock, as it can jam halfway open. Back away from it to allow it to open fully. Avoid contact with the gate when a speeder or ZB is near it.

Sprint around the end of the wall and head for the gate. Press and hold GGP+ to pop the lock when in range. Press action when 4 feet from the gate, turn 180 degrees, and close the gate before the speeder or ZB can reach you.

In the current room, deal with Zs and a ZB. Use QS to SG and move toward the gate but maintain LOS on the ZB. Alyx will usually eliminate them. If the ZB gets by, strafe right and sprint to the end of the Pswy, ducking into the low Pswy to continue.

Run to the left side of the stairs. Alyx will shoot the EB and kill the 2 Zs in the caged area. Run at the cage EP, drop to the floor below, and enter the cage. Turn the valve to open the tank's gas, then shoot a pistol round into the gas stream outside the cage EP.

Run to the back corner of the room, set the pistol to QS, and QS to GG. More BGs will follow and begin cooking at the EP. Keep an eye on the stairs for PSTs, as PSs will drop off and move to the ends of the divider fence.

Keep an eye on the XP below, where an EB is ready for igniting when a group clogs at it. If a ZB moves toward the stairs, shoot it rapidly with the pistol, which may encourage it to light a G. Take cover in the corner with the GCs and wait for the explosion.

Be prepared to GGP PSs away and to shoot ZBs, using the fence for distance.
