Portal Part 34 walkthrough: Learn how to complete Part 34 with specific portal placements and step counts for the Least Steps Test Chamber 16.

Walkthrough
  1. 1
    Shoot one portal at the ground around the corner and the other at your feet. Once you are going up through the one around the corner, shoot a portal elsewhere to land without taking a step.
  2. 2
    Shoot a portal into the larger room, near the middle. Shoot the other at your feet. When going up through the one in the larger room, shoot the portal under you elsewhere to land without taking a step.
  3. 3
    Turn and aim a portal towards the base of the right energy grid. Shoot the other at your feet. Do the portal cancel again to land without taking a step.
  4. 4
    Turn and face the wall opposite the energy grids. Shoot the first portal directly in front of the grid you are standing in front of. Shoot the other where the energy ball is hitting the wall.
  5. 5
    When the energy ball goes through, take three steps to go through the energy grid behind you and shoot one portal where the ball will hit the wall. Shoot the other at the orange light above the receptacle. Take another three steps back out of the energy grid. You should have 10 steps now.
  6. 6
    Shoot one portal at the white wall above the newly lowered piston and shoot the other at your feet. Turn down the hall and shoot a portal at the far white portion near the far barrier. Shoot the other at your feet. Perform a portal cancel as described above to land without taking a step.
  7. 7
    Turn and face the small window above the door to the side of the room. Shoot a portal through here and shoot the other at your feet. From here, you can aim back out the window to shoot at the pushed out concrete slab with one portal. Turn and face the wall behind you and take 3 steps to overlook a pit. Shoot the portal opposite the one on the slab down into the pit. Take one step and fall in. You should have 19 steps.
  8. 8
    As you are flying through the air, shoot a portal where you would land to fling over the barrier. Place one portal near the door here and the other at your feet. While going up through the one near the door, shoot that portal elsewhere to land without taking a step.
  9. 9
    Shoot a portal at the far wall, then shoot the other at the wall near you. Take three steps to go into the portal. If did it right, you can shoot a portal further down the hallway from here. While the portal is traveling, take one step out of the portal and one step back in. Shoot a portal into the room ahead. While the portal is traveling, take one step out of the portal and one step back in. You should now have between 27 and 35 steps.
  10. 10
    Shoot one portal near the base of the only piston in the up position. Shoot the other at your feet. Perform a portal cancel as described above. Now shoot a portal at the ceiling near your current location and shoot the other at your feet. As you are falling, shoot the portal that was on the ceiling where you would land. If you did it right, you should end up flying straight up next to the piston. Move the analog stick in the direction of the piston. On top, carefully aim yourself and run into the chamber lock. You should have between 40 and 50 steps.

Least Steps Test Chamber 16 (LS16)

Goal: 70 Steps

Gold: 40 Steps

  1. Place one portal in the far right corner from where you are standing, then shoot one as close to the elevator as you can. Take one step and jump into it. You should have 2 steps. As you are coming up from the one in the corner shoot a portal anywhere to portal cancel. It will be referred to as portal canceling for the remainder of this test chamber.
  2. Wait for the door to open. Shoot one portal to the far right corner of the next room, and then another at your feet. Portal cancel.
  3. Shoot one portal (the one out in the hall) at the base of the turret here. Then shoot a portal as far near the left of the doorway that the turret was at as you can, then shoot the other at your feet. Portal cancel.
  4. If you are in the right location, you can see diagonally through the hallway. Shoot a portal as far to the ground as you can. Shoot a portal at your feet. Portal cancel in here, then shoot a portal near the corner (not directly in it though) to the other side of the door you just "came from". Shoot a portal at your feet, then portal cancel.
  5. Aim as far down the hall as you can, and as far to the right as you can, then shoot a portal at the ground there. Shoot another at your feet. Portal cancel.
  6. Aim down the hallway, at the floor and shoot a portal there. Shoot the other at your feet, and portal cancel.
  7. Shoot a portal in between the glass wall and the black wall. Shoot the other at your feet and portal cancel.
  8. Shoot one portal at the "X" above the turret to your left, and then shoot a portal under the two boxes behind you. Before they actually fall through, shoot the other portal elsewhere to spread them up. Shoot a portal under one of them to cause it to knock over the turret.
  9. Aim the other way down the hallway and shoot a portal at the other "X" above the other turret. Shoot the other portal under the other box to knock over the turret.
  10. Shoot a portal in the direction of the last turret as far as you can and to the right of the hall. Shoot the other at your feet and portal cancel.
  11. Aim to your left to be able to shoot into a small room across from the two turrets. Shoot a portal there and shoot the other at your feet. Portal cancel.
  12. Shoot a portal into the corner between the two glass walls and shoot the other at your feet, followed by a portal cancel.
  13. Shoot a portal directly above the doorway, then shoot the other portal under all of the boxes to use them to block the doorway partially.
  14. Shoot a portal behind them, across from the doorway and another at your feet. Portal cancel. Immediately duck down to avoid being shot.
Tips
  • Portal canceling involves shooting a portal and then immediately shooting another portal elsewhere while you are still in the air from the first portal's momentum, allowing you to land without taking a step.
  • Pay close attention to the step count as you progress through the Least Steps Test Chamber 16 to stay within the Gold target of 40 steps.
  • Use the environment to your advantage, such as knocking over turrets with boxes.
