Big Walk: solving the 4166, 1899 coordinates puzzle

This puzzle shows up early in your Big Walk run, and it has a way of tripping up groups in a hurry: without the right prerequisite, it's flat-out impossible to solve. You come across a locked box containing a MacGuffin, and next to it, a simple plank engraved with the numbers 4166, 1899. No other clue. No wonder it stumps everyone.

Good news, it's not a riddle. These are coordinates. Bad news: you have no way to read them until you've completed a very specific step elsewhere on the island.

Step 1: finish the red tower

Before you even think about the coordinates, take care of the red tower. Place the five required MacGuffins in its console. This action unlocks a key you need to craft, then use to open a room located right next to your session's spawn point.

This room, a kind of gym with a peculiar vibe, hides the tool that will unlock everything.

Step 2: use the paper map, not the 3D map

In this room, you'll find a huge 3D map laid out on the floor, showing the entire island with the location of all the MacGuffins and notable landmarks. It's impressive, but completely useless for your problem: it doesn't display any coordinates.

The real key is the paper map sitting on the table in this same room. Open it and you'll see latitude and longitude marked along its edges. Locate 4166, 1899 on these axes to roughly pinpoint the area you're looking for.

Step 3: find the right spot on the island

Once you've identified the area on the map, head toward the south-center of the island. The landmark is located between the spot where the railway begins its curve and the spot where the chairlift dives into a tunnel.

Be careful though: the journey is long and the island is full of distractions. It's easy to get sidetracked farming something else along the way and forget your original objective.

Step 4: coordinate with your group

This puzzle is designed for co-op, not solo play. Before heading to the coordinates, leave at least one group member stationed near the locked box, right where you found the numbers in the first place.

• One player stays near the locked box containing the MacGuffin.
• Another heads to the area indicated by the paper map (south-center, between the railway and the chairlift tunnel).

Step 5: find the hidden button

Once there, look for a button hidden on the side of the rocks. It's deliberately camouflaged, so don't expect to spot it at first glance. You really need to scan the rock face carefully. Once you've found it, hold the button down. The player stationed near the locked box will then see it open and can grab the MacGuffin inside. Puzzle solved.

Note

The difficulty here isn't in the execution, but in discovering the mechanic itself. Once you know you need the red tower and the paper map, the rest becomes a simple coordinated stroll between teammates.
