Navigate Half-Life Part 41: use the hornet gun to destroy doors and the osprey, and defeat vortigaunts with your guard's help.

Walkthrough
  1. 1
    Past the guard, find health packs at the base of a slanty beam.
  2. 2
    Return to the alley via a door near the slanty beam.
  3. 3
    Ascend the slanty beam or return to the roof the first way.
  4. 4
    From the roof, jump to a broken wall, then to a floor piece.
  5. 5
    Alternatively, crouch-walk down a broken wall to a floor piece.
  6. 6
    From the floor piece, walk along a metal beam to another floor piece.
  7. 7
    Jump from the second floor piece to the floor piece next to the doorway.
  8. 8
    Proceed down the hall to another doorway.
  9. 9
    Position yourself to see large doors with red STOP signs across the helipad area.
  10. 10
    Quicksave and fire exactly 55 altfire hornets at the large doors.
  11. 11
    If you destroy them, quickrestore and try again; quicksave if successful.
  12. 12
    Keep the hornet gun out and run backward through the doorway.
  13. 13
    Back up toward the helipad center until you hear an explosion behind you.
  14. 14
    Immediately run forward to the doorway you came through.
  15. 15
    Stop just past the doorway, turn around, and use altfire hornets to finish destroying the large doors.
  16. 16
    As soon as they blow up, turn and run down the hall, dropping onto the floor past the doorway.
  17. 17
    Run for the slanty beam and use it to get back on the roof.
  18. 18
    Stay near the top of the slanty beam to avoid marine fire.
  19. 19
    Quicksave each time the osprey stops to drop marines.
  20. 20
    Hit the osprey with altfire hornets until it circles again.
  21. 21
    If you destroy it, quickrestore and hit it with almost enough altfire hornets to destroy it again.
  22. 22
    Wait until the osprey flies directly over your roof, then finish it off with the pistol when it's not directly overhead.
  23. 23
    Alternatively, wait until it flies by without dropping marines, then finish it off with altfire hornets.
  24. 24
    After the osprey is destroyed, return to the helipad area.
  25. 25
    Watch for an alien grunt in the hallway leading to the helipad; use hornets or the pistol.
  26. 26
    Quickly shoot down any surviving marines from the hallway with the hornet gun.
  27. 27
    Find the other big doorway to the right of the one you blasted open.
  28. 28
    Go through it and down the ramp to the locked supply room door.
  29. 29
    Take down the nearby alien grunt with RPG rockets.
  30. 30
    Go past the grunt and locked door to a door returning to the alley.
  31. 31
    Enter the building on the left and go to the supreme supply room.
  32. 32
    Get what you need from the supreme supply room.
  33. 33
    Have the security guard follow you to the other supply room's locked door.
  34. 34
    After the guard opens it, enter and use the first aid and HEV stations if needed.
  35. 35
    Retrieve your other security guard if still alive.
  36. 36
    Return to the second supply room and have that guard follow you.
  37. 37
    Go through the big doors you blasted open earlier.
  38. 38
    Proceed to where section c2a5f loads.
  39. 39
    Go up to the corner where the big hallway turns left.
  40. 40
    Move to where your security guard(s) will see the vortigaunts and start shooting.
  41. 41
    Run back for cover (press the cover button to crouch behind walls or objects) before you get zapped by the vortigaunts.
  42. 42
    After your guard(s) are killed, stay at the corner and shoot hornets.
  43. 43
    Duck for cover when a vortigaunt charges up.
  44. 44
    Switch to the assault rifle or shotgun if any vortigaunts reach your corner.
  45. 45
    Cautiously move past the corner, as some vortigaunts may still be present.
Tips
  • The slanty beam is faster but more dangerous to ascend; quicksave and retry if you fall.
  • Crouch-walking from the beam to the roof can help.
  • A tripmine placed high on the wall to the right of the doorway can be useful; remember to duck under it.
  • The psychic guard may reappear in the alley.
  • Marines might shoot at you if you are too far back on the roof.
  • If the osprey is destroyed, it won't fly over you but will fly by without dropping marines.
  • An alien grunt may be in the hallway to the helipad, even if your tripmine got one.
  • The vortigaunts teleport in a few at a time.
  • It may be better to position your guard(s) further back from the corner for backup fire support before horneting the vorts.
  • Vortigaunts run back to your position faster, making them harder to kill unzapped.
