Polygon has published a guide explaining where to find megaphones in the multiplayer exploration game Big Walk, a useful item that lets players communicate with allies from a distance, given the game's proximity-based voice chat. Megaphones are not guaranteed to appear on every playthrough, but when they do, they always spawn in one of three fixed locations atop distinctive yellow cube structures.

The structures appear as yellow squares on the 2D map and stacked yellow cubes on the 3D map, and are located north of the yellow tower on a northern cliff, in a forest east of the green tower, and along the southern shoreline (best reached via the green tower's ski lift or by swimming round the southwest corner). Reaching a megaphone requires a friend to boost the player up the oversized blocks, reflecting the game's emphasis on co-operative problem-solving, and once collected, megaphones can only be carried in hand or on a backpack, not in side satchels.
