Big Walk Black Tower: Late-Game Guide
Quick Answer: the Black Tower is the late-game fifth Tower Key stage, reached after the first four Tower Key gates. Gameplay evidence associates its sequence with the Black Sphere. Exact puzzle steps, a separate Black Key, and the player term "prophecy" still need verification.
When It Unlocks
The Black Tower stage is the fifth key gate in the gameplay-verified route, after Red Bridge / Map Room, Green / Lift, Blue / Train, and Yellow / Tunnels. Verified (gameplay)

Puzzle Structure
Available evidence does not support a stable, exact puzzle solution or reusable input list. Puzzle layouts, required actions, and any random elements remain held pending verification. Needs verification
Black Key
No independent Black Key entity is verified. The supported term is Black Tower Key, the fifth Tower Key associated with the Black Sphere gate. Do not substitute a community shorthand for a confirmed separate item; see the dedicated Black Key page for the evidence boundary and White Key comparison. Needs verification
What Is the Big Walk Prophecy?
Players sometimes call the Black Tower sequence a prophecy or vision. Neither term is verified as official terminology, and this guide does not assign it a confirmed meaning, trigger, or reward. Needs verification
Where to Go Next
Use Black Sphere for the fifth gate and cautious after-wall guidance. Use How to Go Beyond the Wall if your goal is the official Big Wall achievement rather than the main gate path.
Big Wall
Big Wall — go beyond the wall is an official achievement. Exact crossing instructions are community-reported and separate from the verified Black Tower prerequisites. Verified (official)
