Story: Gateway Engines & Strange Object Guide
The story of ASTRONEER is told through the endgame progression of the seven planets, the activation of the Gateway Engines, and the final arrival at the Strange Object. It culminates in a sequence that takes the player from planetary exploration to the game’s closing scene and credits.
Endgame progression
Each planet has a Gateway Engine. After activating all seven Gateway Engines, the player must bring one Geometric Triptych from each planet to the central Gateway Chamber.
Activating the portal
Placing the seven Geometric Triptychs into the correct slots activates the portal. Once the portal is active, the player can interact with the Strange Object at the center of the platform.
Doing so triggers the final scene and the credits.
Gateway Chamber slots
The seven slots are arranged in order from nearest to the center to farthest from the center. Each slot corresponds to one planet and accepts that planet’s Geometric Triptych.
