Half-Life 2 Hints

Section 1: Help from Alyx (d2_prison_06)

  • 1 of 18: Bust open the supply crate that's near where you fall, then head out through the doorway and drop down to a rubble passageway.
  • 2 of 18: Move forward until you see Alyx ahead of you briefly, then drop down and run along under her until you reach a large Combine door.
  • 3 of 18: She'll drop down and open the door, after which you need to follow her into an elevator.
  • 4 of 18: When you exit the elevator, be ready for your first partner combat with Alyx.
  • 5 of 18: When that's over, go into the side room with the large Combine computer console and wait around while Alyx locates Dr. Vance.
  • 6 of 18: There'll be another fight with Combine soldiers right past the force field that Alyx deactivates.
  • 7 of 18: When Alyx opens another room and goes inside, check a nearby side room for a supply crate before following her.
  • 8 of 18: After she talks with Dr. Vance and sends him on ahead, she'll open a door for you to go through and then lock it behind you.
  • 9 of 18: You can optionally look for supplies past the side door that's ajar (shoot the fast headcrabs through the opening first), then bash your way through the debris and go out the other door to find a closed barred gate.
  • 10 of 18: Past that gate is a small office and another closed gate.
  • 11 of 18: Be ready for three headcrabs who assault you in the vent shaft, plus a cleverly placed laser tripmine and several fast headcrabs in the room past the other end of the shaft.
  • 12 of 18: TIP: Right after you exit the vent shaft, check out the two sentry guns set up past the unopenable doors on the right. You can blast them with the gravity gun now if you use a barrel to hop up to where you can aim at the sentry guns through the broken glass above and to the right of the doors.
  • 13 of 18: Past the next Alyx-opened gate is a small room with an infinite frag grenade crate. Fill up on those, since several soldiers are about to open a nearby gate and come in after you.
  • 14 of 18: There are two sentry guns near the other end of the large room the soldiers came out of, so bounce some frag grenades back there to knock the sentries over.
  • 15 of 18: Also bounce grenades around the next couple of corners to help you finish off the soldiers in the next little hallway and in the large room with the force field. (Remember to return to the infinite grenade crate frequently to refill.)
  • 16 of 18: Past the plug-in room is a spot where a sentry gun is trying to hide in a corner on the right, but you can easily pick it up with the gravity gun and toss it away before it can shoot you.
  • 17 of 18: However, the two sentry guns down further will be able to shoot you easily if you didn't knock them over using an earlier tip. (If you didn't, use frag grenades to knock them over now.)
  • 18 of 18: Get the supply crate that's near those last two sentries, then head down the nearby checkered-floor corridor to reach Section 2: Using Friendly Sentry Guns.
