Guide to Part 28 of Half-Life: Opposing Force, covering the launch control room, laser traps, and the journey to the 'Apprehension' chapter, including enemy encounters and item locations.

Walkthrough
  1. 1
    From the 'BLAST DANGER' doors, jump-crouch onto the small ledge to the right. Turn left, get onto the higher ledge, and jump-crouch onto the window of the launch control room. Hit the launch button through the window.
  2. 2
    Go through the 'BLAST DANGER' doors and down the hallway to a room with laser alerts and explosive packs guarding stairs.
  3. 3
    Push the smaller metal crate to the back of its side area. Jump-crouch onto it, move to its left edge, and jump-crouch onto the stairs' side rail. Move forward, turn right, and go through the door at the top.
  4. 4
    Past the door, turn left and crouch-walk along the left wall to sneak-shoot two marines with the .357 Magnum.
  5. 5
    Check the first room for a first aid station. In the second room, use the big red button between the windows to launch the lambda satellite rocket.
  6. 6
    After the rocket launches, the door reopens. Go back to the big red doors and use the control panel nearest the closed doors to return to section c2a2g.
  7. 7
    In section c2a2g, turn left at the tracks to find a new area with a ladder. Climb down to a room with supplies and a rail track. Break open wooden crates and check the tops of the two largest green crates.
  8. 8
    Get on the ugly old rail car. Jump-crouch onto its front end and crouch-walk forward and right to drop onto the ledge to the right of the track. Follow this ledge to reach the 'Apprehension' chapter.
  9. 9
    In section c2a3 ('MILITARY AMBUSH AND SILO'), continue along the right-hand ledge to an open area. Sneak-shoot the three marines with the pistol, or lure them back and shoot them from a distance.
  10. 10
    Grab their weapons, go through their door, and start down the ladder. Strafe right near the broken point to fall into the water without hitting the crate. Bash the crate for shotgun shells.
  11. 11
    Push open the underwater door, go down the corridor, and through another door. Run up the stairs on the left to breathe.
  12. 12
    Check the floor past the stairs for an assault rifle clip. Go through the doorway and along the unbroken walkway.
  13. 13
    In the next room, use the assault rifle to kill the zombie under and on the stairs. Check under the stairs for bullet clips. At the top, use the first aid station if needed and bash the crate for an armor battery.
  14. 14
    Past the next doorway, go along the walkway to the right and bash the crate for a bullet clip.
  15. 15
    Crouch-drop onto the large black-and-yellow-striped divider wall. Move back to drop onto a crate, bash it for an assault rifle clip.
  16. 16
    Jump over the railing, dive down, and quickly head for the underwater doorway to the right. Swim through the passages, ignoring leeches, until you reach section c2a3a.
  17. 17
    In section c2a3a ('ICHTHYOSAUR TANK AND CROSSBOW'), continue swimming past a door on the right until you reach rubble. Crouch-swim through the rubble.
  18. 18
    In the next hallway, surface to catch your breath. Dive down and bash the floor grating with the crowbar. Swim down through it.
  19. 19
    Take a right at the path intersection and swim up to bash another grating. Surface in the room beyond.
  20. 20
    Dive and look on the floor for AR grenades and crossbow ammo. Find the door with the computer bank in front of it. Push the computer bank to knock it over.

Tips:

  • The jump to the ledge near the 'BLAST DANGER' doors is difficult; you may slide back down.
  • The text mentions a shortcut to hit the launch button through the window, but the walkthrough assumes you don't use it.
  • When dealing with the laser alerts and explosive packs, push the smaller crate all the way to the back of its side area before jump-crouching onto it.
  • When sneaking past the marines after the launch control room, use the .357 Magnum for quick kills.
  • If you let the marines in section c2a3 see you, retreat far back along the ledge where they cannot fire at you.
  • When falling into the water after the ladder, strafe right to avoid hitting the crate.
  • In the underwater sections, swim as fast as possible and ignore the leeches.
  • When encountering the rubble in section c2a3a, you may need to
