The Orange Box: Half-Life 2: Episode Two Hints

Chapter 2, Section 4

  • 1 of 3: See the Alyx Gets Healed hints for more detailed info on this chapter section.
  • 2 of 3: There's only one grub left, and it's near the spot where the antlion guardian head-butts some boards and roars at you.
  • 3 of 3: Look through the gaps near the left end of the boards to see 1 grub on an explosive barrel. Hit him with a gravity gun burst (or whatever) to finish this pesky achievement at last.  [333]
