ARC Raiders Controlled Access Zone Explained: Complete Puzzle Guide
In ARC Raiders, some of the most rewarding content isn't about raw combat—it's about coordination, timing, and smart preparation. The Controlled Access Zone in Dam Battlegrounds is a perfect example. Positioned in the northern part of the map between The Breach and the Power Generation Complex, this encounter offers top-tier rewards but demands teamwork and precision.
For players chasing rare loot, valuable crafting resources, and faster progression into advanced gear, mastering this puzzle is a major advantage.
Where to Find the Puzzle
The Controlled Access Zone is hidden inside the dam structure itself. The quickest way in is from above.
Look for a ladder on the dam's surface and descend into a deep vertical shaft. Inside, you'll find a layered interior filled with narrow walkways, staircases, and partially flooded sections. This multi-level chute system is where the puzzle takes place.
Why Cooperation Is Required
This activity cannot be completed solo.
With squads limited to three players, you'll need at least one additional player outside your team to complete the puzzle. That means forming temporary alliances or coordinating with others during the match.Gear up for victory—get the best ARC Raiders Items today and dominate every Expedition!

Step-by-Step Puzzle Walkthrough
Step 1: Find the Fuel Cell
Your first task is to locate a fuel cell somewhere within the chute system. Its spawn location changes each match, so careful searching is required.
Common places to check:
Flooded lower sections
Underwater areas with poor visibility
Near destroyed ARC units
Along stair edges and narrow platforms
The fuel cell can be difficult to spot, especially underwater. Clear nearby threats first to avoid being interrupted while searching.
Step 2: Power the System
Once you have the fuel cell:
Bring it to the upper level of the chute
Insert it into the machine near the suspended Rocketeer
This will activate the mechanism and unlock a nearby room. Inside, you'll find one of the four buttons needed to continue.
Step 3: Locate the Remaining Buttons
There are four buttons in total:
One is always inside the unlocked room
The other three spawn randomly around the area
Check locations such as:
Behind pipes and industrial structures
Along railings and staircases
Near support beams
Close to the vault door
In darker corners of the environment
Each player must stand on a different button, so spreading out efficiently is key.
Step 4: Activate All Buttons Simultaneously
All four buttons must be pressed at the same time.
This step requires precise coordination. If the timing is off, the puzzle resets, forcing your group to try again—often while under pressure from enemies or rival players.
Step 5: Repair the Vault Door
After successfully activating the buttons, a second door becomes available. Instead of opening immediately, it requires repairs.
A panel will display a list of materials needed to unlock it. These requirements change every match and may include:
Metal parts
Powercells
Mechanical components
Industrial batteries
Your team must provide the exact items listed to open the vault.
Preparation Tips
This final step is where many attempts fail.
The required materials may not be nearby, and searching for them mid-run increases your exposure to danger. To improve your chances:
Bring commonly requested components into the match
Stockpile materials from previous runs
Coordinate with teammates to cover different resource needs
Preparation turns a risky situation into a manageable one.
Rewards Inside the Vault
Successfully completing the puzzle grants access to a high-value loot cache, including:
Advanced crafting materials
Rare equipment and resources
Components used for late-game upgrades
These rewards can significantly speed up your progression and help you unlock stronger gear faster.
