Complete Half-Life 2 Part 40 walkthrough. Learn how to use the Gravity Gun with Dog to defeat Combine soldiers and Ant Lions.

Walkthrough
  1. 1
    Access building #3 then return to building #2.
  2. 2
    Grab Dog (DB) through the energy pulse (EP) but do not take it out. Launch or drop DB into the toppled shelving to the right of the EP, then quickly pull it out via the window.
  3. 3
    Place DB in building #3 and trap it in the corner with supply crates (SCs) and debris.
  4. 4
    Move the planks, start the thumper, grab any available goodies, then head out for the island boulders.
  5. 5
    From the edge of the building #3 outcropping and the planks below, use the Gravity Gun (GGP) with DB past the outcropping blocking your view of the base of the XP ramp.
  6. 6
    Continue crossing and placing your planks and sheet steel.
  7. 7
    If DB comes back before you reach the ridge, launch it back over the big boulder between you and the ridge ramp so that the boulder traps it there.
  8. 8
    When you close in on said boulder, DB may roll around it to you.
  9. 9
    Take DB over the ridge to the lowest boulder on the guardian side of the ridge.
  10. 10
    SAVE your game.
  11. 11
    Launch DB as far as you can toward the rebel Man-Gun Turret (MGT).
  12. 12
    Sprint to the 3 energy barriers (EBs) and launch them at the guardian.
  13. 13
    If possible, grab DB on your way and GGP+ it to the safety of the rock niche past the rebel EP.
  14. 14
    If not, use GGP-/+ EB #3 at the guardian and sprint to the niche.
  15. 15
    If the rebel MGT is unable to attain Line of Fire (LOF) on the guardian, you'll have to either bait it out into the open or expend tons of ammo venting it yourself.
  16. 16
    When complete, follow the Vortigaunt (Vort) and its instructions.
  17. 17
    DB has no ill effect on the guardian.
  18. 18
    Ant Lions (ALs) hate DB and will ignore pods and Barnacle Grapples (BGs) when it's close by.
  19. 19
    You must launch DB at BGs then throw pods for extra measure or deal death for yourself.
  20. 20
    ALs will attack you while you're holding DB but cause no damage.
  21. 21
    Drop DB to climb and deactivate thumpers and to operate MGTs.
  22. 22
    GGP+ DB ahead of you when safe to, then sprint to it to save some drawn-out bouncing (BHing).
  23. 23
    Drop DB to deactivate thumpers #1 and #2.
  24. 24
    BH from thumper #2, upslope toward outpost #1.
  25. 25
    When you have LOS on BGs, GGP+ DB at them then switch to the Shotgun (SG).
  26. 26
    Sprint at the BGs and rapid-fire/SG everyone the ALs don't get first.
  27. 27
    Retrieve DB (RA DB) and continue to outpost #2 and launch DB into the circular concrete walls behind outpost #2.
  28. 28
    Quick-Switch (QS) to the SG and sprint in for close-quarters (CQ) rapid-fire/SG fun.
  29. 29
    Clear the area of BGs then pick through the SCs in the circle for supplies.
  30. 30
    RA DB and enter outpost #2.
  31. 31
    Drop DB and move in tight to the MGT to minimize AL jostling and shoulder it.
  32. 32
    Expect to be pushed away from the MGT before all 4 Overwatch soldiers (OBGs) storming from the beach have been retired.
  33. 33
    You may be required to CQ RT/SG the remaining.
  34. 34
    Return and GGP- DB, return to the beach and disable thumper #3.
  35. 35
    Now you must deal with outpost #3 and at least 6 OBGs between it and thumper #3.
  36. 36
    Move to the right of the rock wall and locate the outcropping at your 12:00.
  37. 37
    GGP+ DB to the outcropping then sprint to it.
  38. 38
    RA DB then swing counter-clockwise (CCw) to the lee side of outpost #3 then crouch and recoup suit power.
  39. 39
    While you recoup suit power, look along the beach for a much smaller outcropping of stone; 2 OBGs are using it to send lead and for cover (press the cover button to crouch behind walls or objects).
  40. 40
    When ready, stand, GGP+ DB to the left edge of the outcropping then sprint to it, SG ready.
  41. 41
    If you're lucky, you may have clocked a BG with DB; RT/SG one or both.
  42. 42
    Crouch and recoup, stand and BH to the next outcropping to your 10:00; there's a BG behind it.
  43. 43
    Swing around it and DB him, RA DB then GGP+ it upslope past the crates then sprint upslope SG ready.
  44. 44
    3 OBGs appear from the left; RT/SG all 3 then RA DB.
  45. 45
    Take cover to your left from outpost #3, use the rock for cover and creep toward #3 till you have LOS on #3s EP.
  46. 46
    GGP+ DB at the EP then sprint SG ready to RT/SG the contents of the outpost.
  47. 47
    Do not enter outpost #3 till all BGs are dead.
  48. 48
    Be prepared to empty the tube with RT/SG and strafe out of LOF to reload or to switch weapons or to RA DB and use it if you run out of SG rounds.
  49. 49
    Luck out with good SCs then head to the caves.
  50. 50
    Grab DB from the ALs, ensure the SG is in QS then run into the caves; the ALs will follow.
  51. 51
    Don't get hung up on the Manhacks (MHs); GGP+ DB forward then GGP-/+ the MHs into walls.
  52. 52
    QS to the SG and continue into small room #1; you may need to RT/SG cave BG #1.
  53. 53
    RA DB and exit the small room and go left.
  54. 54
    Sprint along the narrow tunnel, GGP+ 1-2 BGs in your way to and through to the end room.
  55. 55
    There may be 3-4 BGs in it; turn right in the room and DB anyone between you and the XP in the next room.
  56. 56
    Once you're outside, you should have only 1 BG to deal with.
  57. 57
    Most often, the ALs will clear the caves by the time you reenter and head for the Lambda cache.
  58. 58
    You may take some damage, sometimes severe, but to date, nothing the SCs in the cave won't cure.
  59. 59
    Outside the caves, BH to outpost #4 and quickly DB the BG in it.
  60. 60
    Shoulder the MGT, crouch and end the BG firing on you and the ALs from outpost #5.
  61. 61
    RA DB and exit #4, DB the nearest BG then sprint to DB to RA; the ALs retire BG #2.
  62. 62
    Enter outpost #5, locate outpost #6 down slope.
  63. 63
    SAVE.
  64. 64
    Exit #5 and GGP+ DB at and to the left of #6.
  65. 65
    OBGs will pour out from the dark sector (DS) to the right and head for outposts #5 and #6.
  66. 66
    Sprint back into the stone guard post and use the MGT on the BGs running to and advancing from outpost #6.
  67. 67
    When complete, RA DB.
  68. 68
    Continue up slope to the dormant Zombies (Zs) and wake them up.
  69. 69
    From the dormant Zs, BH to the tower ladder; you'll take damage but you don't want to let go of DB.
  70. 70
    On the platform, quickly turn and DB OBG #1 low, recover and do the same to #2 then jump over the railing.
  71. 71
    Drop DB between the 2 SCs then GGP one for the MK.
  72. 72
    Continue to the zigzag path up the hill to the sewer pipe; the ALs will harass and block your movement.
Tips
  • The ALs will ignore the tossed or squeezed pod in favor of attacking DB in or out of your Gravity Gun (GG) grip, so you must plan accordingly.
  • When you are about to go into dangerous close-quarters maneuvering, do not expect the ALs to be advancing on and attacking BGs or covering your rear; they'll just as likely swarm on a stationary you (while holding DB) and/or a launched DB and begin swatting at it.
  • On the way to Nova Prospekt, you will DB far more BGs than the ALs take down.
