Completing the four colored towers in Big Walk is essential for progression, as each provides a distinct form of transportation or crucial map information that aids in navigating the island and collecting items. While players can technically tackle these towers in any order, a strategic sequence can significantly enhance the early game experience.
The red tower, typically encountered first after the tutorial, is arguably the most important. Its completion grants access to a comprehensive 3D map of the island. This map is invaluable for locating major landmarks, the red collectibles themselves, blue backpack structures, and other towers. Crucially, it also tracks which red gourds have already been found, making subsequent collection efforts much more efficient.
Following the red tower, the optimal order for the remaining towers—green, yellow, and blue—can be a matter of player preference, depending on the desired modes of transport. However, a commonly recommended approach prioritizes the green tower next. This tower unlocks a ski lift, which is particularly useful for quickly ascending hills and reaching other towers, such as the yellow one, more rapidly. Additionally, players may find a useful holster near the green tower, located under a glowing balloon in the forest. This item allows for carrying two red items, either personally or by placing them in a backpack, providing a convenient early-game benefit.
The yellow tower is recommended for completion third. It unlocks a tunnel system that connects various areas of the island. While the tunnels offer a flat and easy-to-navigate path, distinct from challenging terrain like cliffs and rocks, their travel speed is not exceptionally high.
The blue tower is considered the least critical for early traversal. It unlocks the island's train system. However, the trains operate slowly and exclusively in a single direction, limiting their practical application for many players. While some may find enjoyment in the circular train routes, its utility is generally less impactful compared to the other unlocked transportation methods.
Ultimately, the choice between prioritizing green, yellow, or blue for the second and third spots depends on individual playstyle and preferred methods of exploration. The availability of the ski lift, the convenience of the tunnels, or the specific appeal of the train system can influence a player's decision on which navigational tool to acquire first.
