The Stacking Yard puzzle in ARC Raiders on the Riven Tides map challenges players to unlock a locked door by finding and pressing four red buttons scattered throughout the area. Completing this puzzle grants access to valuable rewards. Here’s how to solve it step by step.
How to Find the Red Buttons in Stacking Yard
The first step is locating the four red buttons, which are randomly placed in and around the Stacking Yard compound. Their positions vary between raids, though some spots may occasionally repeat. Teamwork helps—any player can press the buttons, and all four must be activated to proceed.
To find the buttons, search these key areas:
- Numbered buildings: Check the edges of ground-floor structures.
- Elevators: Use the elevators at the base of buildings to explore upper floors.
- Pillars and foundations: Inspect the areas where pillars support the main structures.
- Cranes: Examine the cranes, including their staircases and small interior rooms.
- Containers: Thoroughly search around the containers scattered throughout the yard.
Once all four buttons are pressed, the next phase of the puzzle begins.
How to Open the Locked Door in Stacking Yard
After activating the buttons, locate a fuel cell near the containers. It typically appears on the ground, so keep an eye out while exploring. Once found, proceed to the marked elevator location shown in the image below.
To repair the elevator, you’ll need Batteries. After fixing it, place the fuel cell on the elevator platform. If playing with a teammate, one player should stand on the elevator while the other activates it to send the first player upstairs.
With the elevator operational, you’ll reach a previously locked door, now accessible. Inside, interact with the terminal to insert another fuel cell, which will open additional locked rooms and unlock further rewards.
