Big Walk Black Tower: key and cutscene
Unlock the Big Walk Black Tower, find the yellow key, trigger its cutscene, leave through the opened wall and follow the black sphere route to Big Goodbye.
Quick answer
The Black Tower becomes the next main objective after your group completes the four coloured tower routes. Climb to its upper room, take the yellow key from the black pedestal beneath the hanging red sphere, and let the cutscene finish. The barred opening bends outward; step through it and walk toward the giant black sphere to begin the final cooperative sequence for the first ending, Big Goodbye.

When the Black Tower unlocks
Treat the Black Tower as the fifth progression gate, not another tower that wants five loose rewards. The group should first complete the Red, Green, Blue and Yellow tower routes so the island’s map, chairlift, train and tunnel systems are available.
If the tower appears inactive, return to the Map Room and audit the coloured structures. A solved reward left sideways is not the same as a fully banked tower route, and the model is more reliable than the group’s memory.
Find the yellow key inside the Black Tower
Climb through the tower to the upper room. The route’s important object is a yellow key resting on a black pedestal beneath a suspended red sphere. There is no code to enter at this point; taking the key is the trigger.
Gather the group before somebody picks it up. The room changes immediately, and separated players can miss the visual direction the cutscene gives for the exit.
What to do during the Black Tower cutscene
After the key is taken, the room glows red and the suspended mass moves while the barred opening deforms. Let the sequence finish instead of trying to force the previous entrance or search for a second keyhole.
The moving wall is the instruction. Once the opening has bent outward far enough to pass, leave through it. If nothing changes, confirm that the key was actually lifted from the pedestal and give the scene a few seconds before restarting the host session.
Leave the tower and follow the giant black sphere
Step outside through the opened wall and move toward the giant black sphere. The landscape and sphere provide the route; this is a transition into the finale rather than a hidden item hunt around the tower.
Keep the party together before crossing into the next sequence. The rooms inside return to Big Walk’s core split-information design, so arriving with one player far behind creates more confusion than difficulty.
Complete the sphere for Big Goodbye
Inside the sphere, solve the cooperative rooms in the order they open and follow the final exit. Completing that route triggers Big Goodbye and the credits, which is the normal ending rather than the 100% finish.
Do not create a new world after the credits. Reopen the same host save if the group wants Big Game: the remaining normal puzzles, seven purple challenges and final reward delivery all depend on that completed world state.
If the Black Tower route will not progress
Work forward from the last confirmed state instead of repeating the whole island. First verify all four coloured tower routes, then the yellow key, the completed cutscene, the opened wall and finally the approach to the sphere.
- Tower inactive — audit all four coloured tower states in the Map Room.
- Cutscene not starting — lift the yellow key from the black pedestal.
- No exit visible — wait for the barred opening to finish bending outward.
- Credits reached — reload the same host save for the true-ending cleanup.

Hint: the cutscene creates the exitShow a hint
Do not search the old entrance for another mechanism. Watch the barred side of the upper room after the yellow key moves.
Full Black Tower routeShow the full solution
Complete the four coloured tower routes, climb the Black Tower and take the yellow key from the black pedestal beneath the red sphere. Wait for the cutscene to bend the barred opening outward, step through it, walk toward the giant black sphere and complete the cooperative rooms inside to trigger Big Goodbye. Reload the same host save afterwards if you want the Big Game ending.
Frequently asked
How do you unlock the Black Tower in Big Walk?
Complete the four coloured tower routes first. If it still appears inactive, check the Map Room for an unfinished or undelivered tower reward.
Where is the key in the Big Walk Black Tower?
The yellow key sits on a black pedestal in the upper room, directly beneath the hanging red sphere.
What do you do after taking the Black Tower key?
Wait for the cutscene, leave through the barred opening after it bends outward, then walk toward the giant black sphere.
Is the Black Tower the end of Big Walk?
It opens the route to the first ending. The cooperative sequence inside the giant black sphere finishes Big Goodbye; Big Game requires a later 100% cleanup on the same host save.
Why is the Black Tower cutscene not progressing?
Confirm that somebody lifted the yellow key, wait for the barred opening to finish moving and keep the group inside the upper room until the sequence completes.
