Half-Life: Alex | Chapter 8: Captivity
As soon as you start the level, you'll find a hole in the wall. Go through it and find a toilet paper stash.
Continue to the next area, where you can pick up some ammo and a couple of Resins. You'll also find a weapon upgrade station and a battery compartment. Find the empty battery hanging in the cabinet with the xen coral, then insert it into the compartment.
Here's how to unlock the Weapon Upgrade Station:
When you're ready, pull the handle next to the glowing button on the gate and go through. You can find some resin and a pistol magazine in the next room as you move through the broken wall toward the zoo's main entrance. Explore the various exhibits around you to find more ammo and a couple of resins.
When you're ready, return and head deeper into the zoo. Jump off the railing and fight your first swarm of ants. The ants are easy to kill, but don't let them get close to you. When you shoot an ant in the abdomen, it flies into the air and explodes, dealing collateral damage to nearby enemies.
Drop down and pick up two Resin units lying in the rocks above you on your way to the next section of the zoo. Nearby, you'll find a pre-loaded health station and a garage door that needs to be opened by lifting it with both hands. Crabs and zombies await you on the other side. Kill them, then head into the pavilion. The display cases contain ammo, health syringes, and one Resin unit, so check them out. One of them has a passageway leading to the next area.
Once you're through, turn left and go through the door, climb over the boxes, and enter a small room with resin. Turn back and then climb over the feeder with the suction cups hiding behind it on the other side.
Fight your way past the suckers, then climb onto the mannequin on the left to find some resin. Return to the opposite corridor and emerge into a wooded area filled with zombies. Climb the nearby rocks and clear out the zombies as efficiently as possible, then go get some xen grenades on the nearby bridge.
Proceed to where the zombies are waiting in the adjacent buildings. Use grenades to destroy them. Note that there are more grenades near both buildings with windows. There's also some Resin in the nearby feeder. Head under the bridge when you're ready, but be sure to clear out the bubbles before heading out.
In the next room, grab the pistol magazine and head up the ramp to the "Exit" sign. Turn around and you'll find a Resin inside the bird cage. Follow the hallway until you see a sign in Russian. Climb the stairs and you'll find two more Resins at the top. Go back down the stairs and turn back toward the sign. Turn left to find another Resin.
Now turn around and collect the ammo from the windows on the right, next to the trapped head crab. In the next room, next to some boxes, there's a medical syringe and some resin. Continue down the next corridor and you'll hear gunfire to your left. Turn right to grab the resin before continuing.
In the next area, climb inside the wrecked van and hit the Combine soldier with your pistol. Aim for the explosive barrel to quickly kill them, then aim and shoot the ants. Jump down when you're ready to move. Directly ahead, on the cliff, is another Resin.
Next, climb up to the side of the wooden railing and turn left through the hole in the wall. Jump over the wall to the other side and continue on your way. The next area is in a giant metal grate that has fallen to the ground. You can spot it by the foggy floor and the large outlet pipe inside. The outlet pipe contains some Resin. You'll notice it if you walk up one of the ramps.
The first ramp you need to climb is the one on your left. As you enter, you'll come face to face with a zombie. Kill it, then use your multi-tool to fix the chain in the next room, opening the door. On your way back, two mines on the wall will activate. You'll need to disarm them to escape.
The opposite ramp will lead you to a medical station and another hole in the wall. Go through the hole in the wall to be ambushed by ants. Kill them, then enter the storage room ahead to grab the Resin from the dead soldier. This will activate a grenade, so get out of here quickly.
Return to the main path and go through the next door. Kill the bloated man blocking your entrance to the next room. As soon as you enter, you'll see a giant blue shield to your left with a sensor next to it. Pull out your multi-tool and connect the conduit connections until they're fully connected.
Next, find the part of the room that's infested with Xen. Shoot the bubbles until they explode, climb up to where the next sensor is, and activate it with the multi-tool. Complete this chain by also activating the third sensor in the room next to the closed garage door. The third sensor is the trickiest:
When the garage door opens, you'll see two mines. Let the headcrabs activate them as they approach you. Go into the hallway and shoot the remaining zombies and crabs. The resin is on a shelf nearby.
Head to the kitchen, where you'll find some Resins in the pantry cabinets, along with some shotgun shells and a healing syringe. You'll need to power up this room to complete this section. It's a bit tricky, so we've included a walkthrough in screenshots:
Shoot the head crab that climbs up the pipes and solve the next puzzle in the room:
Once the switch is flipped, the shield will deactivate, allowing you to proceed to the next area. But first, return to the hole in the kitchen wall and open the gate again, like this:
On your way back, you'll encounter a squad of soldiers. Quickly dispatch them, and you'll find yourself in a room full of tanks.
There's a medical station in this room, so heal up if you need to. Continue down the hallway and jump off the ramp, which will end the chapter and begin the next one, "Revelations . "
