Shoot the zombie that wakes up immediately in front of you, then leap off the ledge into the dark abyss below. Lift it up with both hands to reveal the passage to the next area. Once the next shield is lifted, you’ll move into a room with a closed garage door. Move to the next room and do exactly the same thing again, this time following the powerline up from a socket near the ground and up slightly to the right. Follow the powerlines slightly to the left, then hit the “trigger” button to twist the conduit junction and shut off the shield immediately in front of you. Pull out your Multi-Tool and touch it against the sensor on the right-hand wall. Surprise! One of them is still alive, so shoot it and keep moving. You’ll walk up to an enclosure with several shields blocking the way, and a pile of armored headcrab corpses. Throw the oil canister down the hallway and shoot it to blow up the headcrab zombie and armored headcrab zombie. Look to your immediate right for a Resin and a pistol clip. As you move through the next corridor, you’ll find an oil canister. Before you enter the next corridor, at the top of the stairwell, turn to your right and collect a Resin on the opposite ledge. There’s also ammo lined up along the railing to your left, and if you turn all the way around, you’ll find a Resin on the floor in the corner. Turn right once again to find a passage with a Resin and a pistol clip on the ground inside of it.Ĭontinue down the passage until you find some stairs. Head back out to the main corridor and continue on down the hallway.
If you travel up the ladder, you’ll find a couple of headcrabs, some shotgun shells, two pistol clips (one inside of an ammo box, one outside) and a Resin. The weapon upgrading station puzzle should look like this: In one of the nearby grates is the grub that goes to the health station. Find another Resin sitting on a ledge across the room.
Another headcrab will jump out, shoot it, and take the pistol clip sitting on the cardboard box behind it. Open the crate with the latch to get at the loot inside, then take another right to find a weapon upgrading station and a health station. Turn right on your first turn, and you’ll see a ladder and a yellow crate. One of the three openings contains a headcrab guarding a Resin, another one contains barnacles, and the third will take you back onto the critical path.Ĭontinue killing zombies and headcrabs until you find yourself in an open hallway with several side-rooms and corridors. Once you’ve killed everything that stands in your way, explore the openings where walls previously stood. Of course, the other zombies will crash through the walls anyway it’s much harder to kill each of them if you only have your pistol. If the dead zombie with the shotgun falls too far into the hole in the floor, you won’t be able to grab the shotgun, and you’ll have to reel the zombie back in, making this a tightrope act. The tricky part is that headcrab zombies will barrel down on you from all sides, crashing through the walls before you can get the shotgun if you take your sweet time. What you want to do here is get the rotary in the position you want it, then re-insert the white bar to lock the zombie in place once again so you can grab the shotgun. After you pull it out, the zombie will begin to descend. You have to jump down to the rotary that’s keeping the zombie strung up in the air, and you have to pull out a white bar that’s got the rotary locked in place. Before you leap off the stairwell, pick up the two pistol ammo clips hidden to your left and right. Back on the main path, travel up a staircase and find a hanging zombie corpse with a shotgun. Detour off of the bridge to the right, then go underneath it to find a Resin. Use the battery to open the door, then travel into the next area. Shoot the lock on the nearby door, kill the armored headcrabs inside of the fenced enclosure, and pick up a battery laying on the ground next to the hazmat suit corpse. On the far side of the room, pick up two pistol clips on the operating tables. In the next room, you’ll see a whole bunch of armored headcrabs fenced in with a dead Combine in a hazmat suit. Open the latch with either hand and pick up one pistol clip. Move through the hallway and stop at the first yellow crate you see on your right. You'll begin the mission in a hallway filled with sewer pipes.
