Half-Life 2: Episode One Hints

Third Control Room

  • 1 of 10: Ride the small lift up, then proceed down the corridor cautiously, letting soldiers come to you for easy zapping.
  • 2 of 10: Past the dangerous explosive wall panel, use the Combine recharger on the left wall and then move on to a small platform with a railing.
  • 3 of 10: Immediately turn around and zap the soldiers that run up behind you, then figure out where to go from there.
  • 4 of 10: Once you get across to the other platform, you'll have more soldiers to fight in the corridor ahead.
  • 5 of 10: After they're dealt with, turn right to find another removable panel cover under a bright red light.
  • 6 of 10: Remove it, then go through the hole and on to where you can jump into a large wall hole near a flaming dead end.
  • 7 of 10: This will bring you to another shaft with energy orbs being constantly shot down it.
  • 8 of 10: Just past that is a panel you can blast out and some soldiers you can zap before going through the wall hole and entering the third control room.
  • 9 of 10: Unfortunately, this machine will screw up, and you'll have to fix it before you can leave.
  • 10 of 10: After you get back to the control room, fire another orb into the machine's wall-mounted power generator just like before to get it going and to open the door in the corner.
