Use the fuse box to start up the lights and open the door.
Go ahead and pick up the flare to activate it and give Alyx a bit of light while she covers the door. Go to the end of the tunnel and into the little supply closet. One drops a fast headcrab when it dies, so be careful. Keep your light on the 2 barnacles so that Alyx can kill them. Once the attack subsides, go forward into the tunnel. She even has a special close combat attack for one-hit kills. Other than that, Alyx should be able to take them out. If one of them pulls out a grenade, use the gravity gun to grab it and throw it away. Your main mission is to watch the zombines. Just hold your ground and let Alyx do the heavy lifting. Just use 2 rounds to set them on fire for some light. Pull out your pistol and shoot a few of the red barrels. There are a bunch of zombine fighting some antlions at the end of the tunnel. Grab the pistol ammo from the end and then head out into the tunnel. It will blow up the glass and clear your path. Another zombine will rush up with a grenade for a suicide attack. Remember to turn off your flashlight and hold your fire. Go to the end to see your first dead zombine. With the coast clear, push forward and grab some more ammo from the dead body. Alyx can easily kill them while they’re on their back. Use the gas can on the zombie and use the gravity gun on any surviving antlions. When it’s ready, push forward to the dead antlions. Once they’re dead or you feel safe, turn off the flashlight and let it recharge. Help Alyx kill the 3 other zombies wandering around by the truck. Grab the extra 6 shells and start pushing forward. There’s a dead civilian back here with a shotgun. This will set it on fire and light up a good portion of the tunnel. Go through and use the gravity gun to hit one of the zombies with the gas can. You need to use the gravity gun and the flashlight to get through these tunnels. Alyx can accurately fire at anything though, as long as she has enough light. If you try to kill all the zombies yourself, you’ll always be out of ammo. Now, there are 2 things you’ll be short on for awhile. Use the gravity gun to knock away the cars blocking your next door. Open it and then use it again to restart the power and open the door for Alyx. Go through and use the flashlight to find the fuse box on the wall. When you’re ready to go, pull out the pistol and shoot the lock on the fence door. Go ahead and get more health and suit energy from the open lockers in the corner. Break the supply box and get the extra ammo that should be inside. Use the gravity gun to pull the shotgun and pistol up and over the bent part of the fence. Go ahead and turn off your flashlight to recharge the energy. This will activate it and give you a nice light source for the next minute.
Use the gravity gun to grab the red flare. All of the zombies are dead, so don’t worry about them. Use the gravity gun to kill the headcrab below. Enter the next section and look down through the broken vent. Turn to the left and climb up the ladder. You don’t need the flare so just leave it or drop it down the vent. Knock the vent off and go inside for a little more vent crawling.Ĭrawl along and grab the health vial with the gravity gun. Look to the side to find the air duct behind a barrel. Get to the end of the room and enter the dark hallway. Use the gravity gun and some boxes to help out.
You can use the gravity gun to throw some boxes around if you really want to help. It doesn’t seem like the turret is functioning, so you just have to focus on the zombies.
The room ahead is full of zombies, so hang back and let Alyx kill them. Wait a moment for Alyx to recover and kill the forcefield. Your escape has gotten a lot more complicated.
