Puzzle elements


When you enter the puzzle, you find yourself in a large open room.

  • There are two pillars in front of your with a horizontal purple barrier spanning them as a bridge. The progress wheel is on top of the right pillar.
  • There is a connector available right in front of you.
  • On the left wall is a red emitter.
  • Near the left pillar is a pressure plate next to a fan.
  • On the left side is a room blocked off by standard height grates. Inside is a hexahedron and a swapper with another hexahedron in it.
  • On the right side is a room blocked off by a blue door with a red receiver outside. Inside is an active, detachable fan, angled at the left room.


A basic hint:

[ hint ]
The name of the puzzle refers to the very obvious horizontal purple barrier. Remember that players can pass through purple barriers, but equipment cannot.

If you're struggling to get started:

[ hint ]
The first objective is to get both hexahedrons out in the open.

If you're unable to operate the swapper from outside:

[ hint ]
You can't operate the swapper from outside unless you have enough elevation to reach across the barrier.

If you're getting stuck inside or outside the left room:

[ hint ]
Remember that hexahedrons can be placed close to the fence to reach across. This is true both inside and outside.

If you're running out of items to feed the swapper:

[ hint ]
If you position some active equipment close to the fence, you may be able to reach across if you need to. This will make the equipment inactive, though. Be sure to look carefully at the fan in the right room for more stuff.

If you're not sure what the ultimate objective is:

[ hint ]
You have to get two hexahedrons to the top of the pillar to start your journey.
