Blue Tower
CommunityCommunity-sourced: based on player reports and not yet verified by this site.
The Blue Tower is one of Big Walk's four main colored towers. Completing its five puzzles rewards the key that unlocks the monorail train, tied to the Big Ride achievement.
The Blue Tower follows the standard tower structure: five puzzles around the area, each rewarding a collectible, with the final key waiting on the roof. After the key is shaped at the tower's key cutters, it unlocks the main train station and its monorail, the fast-travel ride tied to the Big Ride achievement. Most community walkthroughs recommend leaving the Blue Tower for the later part of the run, after the Red, Green, and Yellow Towers. Specific puzzle solutions for the Blue Tower are still being documented by this site.
