Big Walk: How to Solve the Green Flare Puzzle

On the east side of the map in Big Walk, you'll come across a green slide structure that faces south. If you climb up the structure, there is a red button on each side. The one on the left is below a black tube that fires a green flare, while the other is by itself and doesn't have a visible effect. To solve this puzzle, you or a friend is going to have to go on a little adventure while the other one of you is left behind.

How to Solve the Green Flare Puzzle in Big Walk

You can find the start of the green flare puzzle at map coordinates 3660, 2040. It's on the beach below the green platform headphone puzzle, near the Blue Tower. So, if you're trying to complete puzzles to unlock the Blue Tower's control panel key, this could be one of the ones you solve to gain another red control panel piece.

What Equipment to Use

You're going to want to grab some walkie-talkies for this puzzle. Unless you want to stand there and occasionally pop off the green flare while constantly holding down the activation button on the right, walkie-talkies are neccessary.

Thankfully, there are two by the Red Tower that aren't hard to spot. One is on a yellow stand that's sitting on the cliff below the Red Tower; it's overlooking near the top of the orange railway tunnel. The second is in the ravine below the Red Tower, on a blue stand that you have to walk across a fallen log to get to.

When you have a pair of walkie-talkies, head to the slide at the coordinates above.

Where to Go to Complete the Puzzle

Waiting on top of the slide set off the flare while a second player races towards the area to the south. The flare will shoot into the sky and plummet back down to the location of the puzzle's reward. While it'd be nice to get a control panel piece for just following a brightly colored flare, that's not it for this puzzle.

As the player travelling player follows the flare, they will need you to periodically set the flare off again. You can send up a new flare every 40 seconds or so. The black tube will reset its position on the top of the slide, so you'll know when it's available. By the time you can shoot another flare, the last one will be completely gone and leave no trail to follow.

The travelling player needs to head up the incline from the beach, and they'll find themselves near a lantern. From the lantern, they should walk north, down towards the tiny section of beach at location 2 on the map above. Location 1 is the start of the puzzle.

Direct them to head out to the shore and turn around to face the rocks. They'll see a camoflagued chest hiding under a slab there. This box can only be opened using the second button on the top of the slide. They should radio you via the walkie-talkie to tell you to press and hold the button.

Inside, they will find one of the red gourd-shaped control panel pieces. You can then communicate with each other for the best meet-up point.

If you decide to complete the green flare puzzle without walkie-talkies, whichever player stays behind will need to keep holding down the button that opens the box, setting off the flare whenever it resets.
