Description: Activate the Treehouse laser. (Secret)
You need to solve all puzzles in the Treehouses Area. To do it watch the video below:
All Credits go to PS4Trophies Channel on Youtube.com
In order to unlock this trophy, you must complete the Treehouse area, located to the far top right of the island (refer to map if needed - named "Treehouse"). The Treehouse area is only accessible via the fast travel boat. There are 56 puzzles to solve in this area in order to reach the laser.
If you are in need of assistance, you can refer to the video below:
The Treehouse area is located between the Keep and the Swamp. It is initially only accessible by activating one of the many boat locations around the perimeter of the island and then sailing to the back entrance of the Treehouse area. Once you work your way through the Treehouse puzzles, you'll be able to drop a bridge leading to the Keep, allowing you to access the Treehouse area from land.
The Treehouse is the first area to introduce you to Suns in the puzzles, so this is where you'll find your Sun tutorial. In addition to Suns, the Treehouse puzzles also use black/white squares, tetris shapes, and multi-colored squares and sun. So you'll want to make sure you've done those tutorials first.
For a walkthrough of the Treehouse area, use THIS LINK for the puzzle solutions.
Once you've solved all the puzzles and created the walkways, you'll now need to activate a panel on the center tree, which opens a nearby door for a short amount of time. The only way to make it to the door in time is to solve the two orange walkways such that they overlap, making a shortcut between the two trees.
Once you get inside the treehouse, activate the laser panel and the achievement will unlock.
