Navigate the treacherous paths and intense combat of Part 3 in Half-Life: Alyx. This guide details enemy encounters, environmental hazards, and strategic approaches to overcome challenges.

Walkthrough
  1. 1
    Proceed through the narrow path, using the Gravity Gun (GGP) to clear debris with your Combine scanner (ET). Send the ET to the blockage and then use the one you've been dragging. Take cover from Assault Squads (ASAs) on your right. Clear remaining debris and sprint through the passage, then turn left.
  2. 2
    Expect up to three ASAs from the open area ahead and to the left. One may attack while you clear the blockage. Stay to the left while working. Use a combination of running, crouch-walking (BH), and sprinting into the open area and then right towards the beginning of the ledge. Sprint along the ledge, using the GGP to clear webbing in advance. Continue sprinting at and over the ledge into the low wet area.
  3. 3
    Note on ASA Combat: ASAs are easier to kill from their bellies with 1-2 pistol rounds. For close quarters (CQ) combat with ASAs, use the Shotgun (SG) at 12-15 feet to minimize collateral damage from its burst.
  4. 4
    Healing Larvae: Be aware of the healing properties of small larva nodes excreted by squished larvae.
  5. 5
    Continue to the next area, dropping off the ledge, running through items, and climbing the ridge. Enter the next area and move right to cover. You will be in a larger area before ASAs can react. If spotted shortly after climbing out, ASAs may enter the small low wet room and attack.
  6. 6
    In the next cave section, there are barnacles above the water, Antlions (ALs) in the distance, and an unseen distant ASA. Position yourself on the dry spot with the water and barnacles between you and the ALs. Wait for barnacles to drop their prey before moving. Advance along the left perimeter to lure distant ALs, then retreat to your position. Use barnacle tongues to your advantage against approaching ALs. Allow barnacles to feed before proceeding. Use the left perimeter again to maneuver and activate the next two ALs and the ASA. Retreat to the edge of the water and hold your position.
  7. 7
    When the two ALs appear, sprint along the left side of the cavern as they approach. If barnacles didn't get them, they likely will as they pursue you towards the ASA. If the ASA appears between the wet area and a stalagmite, strafe to avoid its spit while advancing for CQ. Use the GGP to push it aside or clear your path. As you pass the ASA, approach a stalagmite with barnacles to its left and in the middle of the path. Slow down, hug the stalagmite, then sprint into the next area.
  8. 8
    The next area contains one ASA and several ALs. Sprint into the water for protection until you exit. Keep an eye on the ASA's bright body to either evade or kill it as you exit the water. Run left into the next tunnel and sprint. An ASA at the far bend will attempt to lure you deeper into the narrow tunnel. Two more ASAs are hidden in a pocket cave past a small side tunnel.
  9. 9
    Slow to a run, then sprint to recover. Look for the small tunnel on your left and begin sprinting. Sprint past and to the right of the pocket cave, continuing into the small tunnel until your sprint runs out. Continue running to a hole in the floor, from which an alarm can be heard. Drop down to begin Chapter 2, "This Vortal Coil".

Chapter 2: This Vortal Coil

3.2a Shielding the Vort and Alyx

  1. On the ground, run past the two rebels to the ammo crates to restock. Grab one mine and place it about 15 feet inside each of two tunnels. Head down the ramp to Alyx, the Vort, and the Supercharged Combine (SCs). Open the SCs for items like the SMG and HEG. Return to the rebels for dialogue. There are four tunnels: three man-made and numbered (#36, #12, #24) and one unmarked breach tunnel on the far left.
  2. My 4-Step Strategy (MO):
    • 1. While only one tunnel floods with Antlions (ALs) at a time, grab a Mounted Gun Turret (MGT) from a tunnel and carry it to the tunnel you are defending. The MGT, combined with the two rebels, should handle the ALs without using your own ammo.
    • 2. When two tunnels are under siege, drop the MGT at the first tunnel, sprint to the second MGT, pick it up, and take it to the second tunnel. The rebels will position themselves as they see fit.
    • 3. When three tunnels are under attack, place MGTs at tunnels not defended by rebels, still without firing a shot.
    • 4. When four tunnels are about to be attacked, quickly position MGTs at undefended tunnels. Try to position near tunnel #24 or the breach to be close to the SMG or SG crate. Hold your position until the Vort begins screaming about being attacked. Ensure your SMG/SG is full, then head down the ramp with an MGT from the closest tunnel. Position yourself to the Vort's right and hold your position with the MGT held high over Gordon's head. Fire at anything flying over the railing or coming down the ramp. When the MGT burns up, switch to the SMG or SG, continue firing, and begin moving around the ramp.
