Early on in Big Walk, as you and your pals are scurrying around the world solving puzzles, you might come across a curious sight: a structure near the beach with an oblong prize (here at PC Gamer we call it a nubbin) inside a frosted glass container. Hanging on a hook above it: a sign with some numbers on it. Curious!
You've probably already seen a nubbin in a similar container, which could only be accessed when one of your companions held down a button in a nearby location. But what do these two four-digit numbers mean? And where's the button?
