If you’re exploring the Riven Tides map in ARC Raiders, the Stacking Yard has a hidden puzzle here that involves tracking down red buttons scattered across buildings and cranes. It can take a bit of searching since the button locations change each run, but once you know where to look, it becomes much easier. Solving it rewards you with access to secret rooms filled with loot. In this guide we will show you all Riven Tides Red Button Locations & how to unlock secret rooms in Stacking Yard.
All Riven Tides Red Button Locations in Stacking Yard


Head over to the Stacking Yard area. You will find three main buildings here, marked as Building 1, 2, and 3. The buildings are also linked to three big red cranes. Your goal is to find and press four red buttons and they can spawn in quite a few spots:
- Just outside the room’s entrance, including on the railing.
- Inside and surrounding all three structures.
- On the staircases of the cranes, particularly in the corners.
- On the top of the cranes, both inside and outside the small room.
- In between the cranes, and you will need to look in each corner.
In most cases, the buttons will be located near the buildings or at the top of the cranes. You can press the buttons in any order.
How to Unlock Secret Rooms in Stacking Yard


After pressing all four buttons you will notice that green lights will be lit. It will unlock the first secret room at building 1. In the secret room, there may be some items such as weapons cases, loot in drawers and containers and battery slots.


For opening the second room, you need the battery. One player holds the battery while the other player drives the elevator. The elevator driver should remain in the place otherwise, it will reset.
After driving the elevator up, the one who has the battery goes back to the first secret room and places it into the slot. Then the second secret room will get unlocked. Inside you will find Red lockers, weapon cases and loot.
