Location of Controlled Access Zone in ARC Raiders

The puzzle room is located inside the Controlled Access Zone on Dam Battlegrounds. You’ll find it beside the breach area and the pipeline tower structure. This zone is clearly marked on the map and categorized as high loot value, particularly for ARC and mechanical items.

The structure itself spans multiple floors. The puzzle components are distributed vertically, meaning you’ll need to move between lower and upper levels to complete it. Expect player traffic and possible ARC enemy presence, especially mid-raid.

How the new puzzle room works

The puzzle follows a structured activation process. You cannot skip steps, and coordination is mandatory.

Step 1: Locate the power cell inside the room

Once inside the Controlled Access Zone building, your first objective is to find the power cell (battery). It typically spawns on the lower levels, though the exact spawn position may vary between raids. You’ll need to thoroughly check floor corners, storage crates, near wall panels, and along lower-level pathways

The battery is a physical object you must pick up and carry. Be cautious while holding it, as you’re vulnerable during transport.

Step 2: Insert the battery into the upstairs power slot

With the battery in hand, move upstairs to the designated power console. There is a clearly marked slot where the power cell must be inserted.

Once inserted, the system activates and enables the next stage of the puzzle. Without power, the buttons will not function.

Step 3: Coordinate four players to press buttons simultaneously

This is the critical part.

There are four separate buttons positioned around the puzzle room. These must be pressed at the exact same time by four different players. One player cannot trigger multiple switches.

This step requires:

• Voice communication
• Countdown timing
• Proper positioning before activation

If even one button is pressed too early or too late, the system will not activate properly. Make sure everyone is in position before starting the countdown.

Step 4: Open the door and prepare additional materials

After successful synchronization, the main door unlocks. However, you are not fully finished.

To access the inner secured section, you must provide:

• 1 Leaper Pulse Unit
• 12 Metal Parts

The Leaper Pulse Unit is a recyclable epic item that can also be thrown to create a violent singularity. It deals 100 damage with a 10m radius, making it valuable in combat situations. However, here it is used as part of the puzzle progression requirement.

Metal Parts are common mechanical crafting materials that should be pre-farmed before attempting this puzzle.

If you enter the room without these items, you may be forced to extract and return later.

What loot you can expect inside

Once fully unlocked, the Controlled Access Zone rewards players with high-tier loot.

Loot Type	Details
Weapon Crates	High-tier firearms and attachments
Mechanical Containers	Metal parts, crafting components
ARC Loot	High-value ARC-related materials
Additional Locked Room	Requires separate key
Misc Containers	Randomized high-value supplies

The additional locked room inside requires a specific key. This key does not drop as part of the puzzle and must be acquired separately during the raid.

How to prepare before attempting the puzzle

Before entering Dam Battlegrounds with the intention of solving this puzzle, you should:

• Bring at least 3 teammates (solo players cannot complete it)
• Farm 12 Metal Parts beforehand
• Carry a Leaper Pulse Unit in safe pocket if possible
• Clear nearby enemies before beginning
• Secure entrances to prevent third-party interference

The puzzle makes noise and takes time, which increases the risk of other players pushing your position.

Risk versus reward inside Dam Battlegrounds

The Controlled Access Zone is classified as high loot value, which means more competition. It is not uncommon to encounter squads attempting the same objective.

But the upside is access to premium loot in a concentrated area.

Common mistakes to avoid

One of the biggest mistakes players make is activating the battery before teammates are in position. This leads to confusion and failed synchronization.

Another mistake is entering without required materials. You should never rely on finding a Leaper Pulse Unit inside the same room — it is not guaranteed.

Lastly, avoid splitting your squad too far across floors during activation. You need tight coordination.
