Chapter 2: This Vortal Coil - Part One
After a short trek through Antlion caves, Freeman reunites with the Vort at a outpost deep in the mine, defended by Resistance fighters Griggs and Sheckley. After a fierce battle with attacking Antlions, Freeman joins the Vort in a quest to retrieve to Larval Extract, a substance found deep in the nest that is capable of healing the dying Alyx Vance. However, to get to the Larval clusters, they must first worm their way through tunnels and abandoned shafts that the Antlions have made their home.

Notes:
Griggs is the only medic in the Half-Life games who can toss medkits to Freeman from afar
It is impossible for Griggs or Sheckley to die during the Antlion defense sequence
In-game strategy: one turret can easily hold off an entire wave of Antlions
Similar to Alyx, the Vort that accompanies Gordon has rapidly regenerating health, but can still die if overwhelmed by enemies
Trivia:
The title of the chapter is a reference to the phrase "shuffle[d] off this mortal coil" from Shakespeare's Hamlet
The duo of Griggs and Sheckley was inspired by the real life comedy duo of Abbott and Costello, who gained enormous popularity during World War II
According to Portal writer Erik Wolpaw, Sheckley was named after science-fiction author Robert Sheckley
The conversation at 1:32 was meant to be for comedic purposes, but Valve discovered that some playtesters actually became worried that stepping on Grubs triggered Antlions to attack and proceed through the rest of the level avoiding them. However, in-universe it does explain why a bunch of Antlions attacked after Freeman enters the caves
The track that plays at 11:12 is called "Vortal Combat", an obvious reference to the video game series "Mortal Kombat"
"GET DOWN MR. PRESIDENT" moment at 15:08
Seems like some bored Resistance members were having fun with the Grubs as shown at 18:20
First instance of Fast zombies playing dead in a Half-Life game at 18:23
The Vort's line "What next in the parade of constant obstacles" at 22:43 is very similar to a line Dr. Magnusson utters later in the game ("What next in the parade of constant interruptions!"). Mark Laidlaw attributed this to the Vort's hive-minded nature and exposure to Magnusson
While the Vort seems to struggle with the concept of climbing a ladder, the noises at 23:03 indicate that he is familiar with them (though the animation is never shown)
The wrecked Combine transport pod at 26:01 seems to suggest that the Combine tried to infiltrate the Resistance outpost in the mines, but fell victim to the headcrabs instead
The Vort has special melee attacks for zombies, as shown at 27:18
The Vort makes several meta comments about the Half-Life series to Gordon:
At 18:52, he comments on Gordon's knack for physics (or barrel)-based puzzle-solving
At 24:03, he comments on Gordon's tendency to fall down deep pits only to have to climb back up (Blast Pit from HL1 comes to mind)
