The Stacking Yard on Riven Tides hides one of the more involved environmental puzzles added in Arc Raiders' coastal map update. It rewards a medium-value loot room, but only after you find a set of hidden buttons scattered around the area, recover a fuel cell, repair an elevator, and feed power to the locked door.
Where the Stacking Yard is on Riven Tides
The Stacking Yard sits in the central-northern part of the Riven Tides map and is marked as a Medium loot value POI. It's a dense industrial zone built around three large gantry cranes and a cluster of warehouse-style buildings, surrounded by stacked shipping containers. The puzzle plays out across all of it, so expect to move between rooftops, crane platforms, and ground level.
Wasps and Fireflies patrol the area, and other Raiders frequently push the POI for the puzzle reward, so clear the immediate area before committing to the climb.
Finding the hidden buttons

The first stage is the hardest because the buttons spawn in semi-random spots. They appear in and around the three buildings and on the three cranes. Each button uses the standard interact prompt and makes a small click when pressed, similar to other Riven Tides puzzle inputs.
Common spawn zones to sweep:
- Inside the buildings, on desks, shelves, and against interior walls.
- On balconies and railings just outside upper-floor doorways.
- Rooftop corners on the warehouse buildings.
- The staircases and ladders that climb the cranes.
- Inside and outside the small operator rooms at the top of each crane.
- The corners of the crane platforms where the gray steel beams meet the red structure.
A grappling hook (Snap Hook) makes scanning rooftops and crane upper sections much faster. Buttons stay highlighted with the interact prompt at close range, so a methodical sweep of all eight corners on each crane platform tends to find the ones you missed.
The fuel cell and broken elevator
Once the buttons are pressed, the next step is the fuel cell. It spawns on the ground around the container yard, usually near the base of the cranes. Pick it up and carry it to the broken industrial elevator inside the Stacking Yard.
The elevator needs a repair item before it will run. The required part is randomized per match. Duct Tape is a common requirement, but it can ask for other repair materials, so it helps to bring a small stack of common repair items into the raid.
Step 1: Place the fuel cell on the elevator platform. Drop it directly on the platform itself, not on the floor next to it, or it won't ride up with you.
Step 2: Repair the elevator using whatever part the prompt asks for. The interaction completes immediately once you have the correct item in your inventory.

Step 3: Hold the call button to send the elevator up. The button must be held down the entire time the platform is moving, which is the main wrinkle for solo players.
Solving the elevator alone
If you're playing in a duo or trio, one player simply holds the button while another rides up with the fuel cell. Solo, you have to improvise. The cleanest workaround is to ride the elevator up with the fuel cell while a teammate or a friendly player in proximity chat presses the button. Without backup, you can sometimes drop the fuel cell on the platform, hop off, hold the button to send it up partway, and try to follow with a Snap Hook from above, but the timing is unreliable.
Opening the loot room
After the elevator reaches the top, take the fuel cell up the short flight of stairs and slot it into the wall mount. The prompt reads Insert Fuel Cell. With power restored, press the nearby button to unlock the puzzle room door.

You'll know it worked when the door slides open and reveals a small interior with red lockers, metal crates, and standard searchable containers. Loot here trends toward mid-tier crafting materials, weapon attachments, and the occasional higher-rarity drop, in line with the Stacking Yard's Medium loot rating.
Common reasons the puzzle won't progress
| Symptom | Likely cause |
|---|---|
| No prompt at the elevator | You haven't pressed all the hidden buttons yet, or the fuel cell isn't on the platform. |
| Repair option greyed out | You don't have the specific repair item the elevator is asking for that match. |
| Elevator stops mid-travel | The hold-button input was released. It must be pressed continuously. |
| Fuel cell slot won't accept input | You're carrying the wrong object, or another Raider already inserted a cell in this match. |
| Final door button doesn't react | The fuel cell hasn't been seated yet, or another squad already opened the room this raid. |
What to bring before pushing the puzzle
The Stacking Yard is loud. Cranes echo, the elevator is noisy, and the puzzle keeps you exposed for several minutes. A few items make the run smoother without overcommitting your loadout.
- A Snap Hook for fast vertical movement between crane sections and rooftops.
- A small stack of common repair items (Duct Tape is the most frequent ask) for the elevator step.
- One Arc Alloy if you also plan to clear the Shoring Up Defenses quest from Apollo, which uses the same Stacking Yard cranes for its reinforcement objective.
- A door blocker or two, since other Raiders often arrive mid-puzzle drawn by the noise.
The puzzle resets each raid, so even if another squad cracked it before you arrived, you can return on a fresh run and approach it again with the buttons, fuel cell, and elevator back in their starting state.
