Black Tower & Ending Route

Getting to the Black Tower

This is the one tower you can't rush: multiple guides agree the entrance stays sealed until you've completed the Red, Green, Blue and Yellow Towers. It's the tall dark monolith visible from the chairlift in the center of the map.

The six puzzle stations

Unlike the earlier towers, this one wants six collectibles instead of five. One detailed guide (not yet cross-confirmed by a second source, so treat the specifics as likely rather than certain) names six stations: a locked room where one player reads a lit symbol and the other flips a matching switch; a voice-disabled room using red-light signals instead of talking; an obstacle course guiding a vision-blocked teammate by short commands; a gesture-and-tile puzzle; a chairlift-style delivery puzzle carrying shapes across in the right order; and a relay puzzle at the bottom of a well before the stairs close. Multiple sources agree that voice chat is disabled in some of these, so agree on a plan with your group before splitting up — some guides mention using a kettle prop as a visual signal when you can't talk.

The Black Key and the Wall

Place all six rewards in the Black Tower's receiver and climb to the roof for the Black Key. Take it to the Wall — a large gate on the far western side of the island, not the Black Sphere itself, which is a separate, later location. Using the key here unlocks Big Wall as its own trophy before you continue toward the sphere.

Inside the Black Sphere

Past the Wall, the path leads to the black sphere. One detailed guide (single-sourced, so treat as a rough preview rather than a fixed list) describes roughly seven small co-op puzzles across multiple floors inside — split-room symbol reading, totem switches, a timed tomato-toss, a synchronized two-player run to matching switches, wall switches paired with glowing buttons, a viewfinder-directed placement puzzle, and a gesture-based shape puzzle. The exact set may vary with group size. The final puzzle before the credits is described as a three-color gate where each player lights the color matching their own painted body part and walks through together.

The first ending

Completing the sphere's puzzles and walking through as a group triggers the credits and the Big Goodbye trophy — the game's first ending. If you want full completion afterward, seven purple puzzles unlock post-credits as harder remixes of earlier challenges, plus anything you skipped the first time through, leading to the Big Game trophy for finishing everything.
