The Controlled Access Zone has arrived in Arc Raiders, tucked away in Dam Battlegrounds as part of the Shrouded Sky expansion. This isn’t just another side quest—it’s a high-stakes puzzle that rewards players who can coordinate with strangers mid-match. The goal? Unlock a hidden room filled with rare loot, but only if four players work together to solve a multi-step challenge.
First, locate the zone near The Breach and the Power Generation Complex—the easiest entry is by sliding down the ladder on the dam wall. Inside, the puzzle begins: four hidden buttons must be pressed simultaneously to open the first door, but their locations shift each match. Meanwhile, a second door awaits, its repair requirements randomized from match to match.
A Four-Player Challenge
Unlike most Arc Raiders* objectives, this puzzle cannot be completed solo or even in a trio. The game’s 3-player party limit forces collaboration with randoms—a risk worth taking for the potential rewards. The process starts with finding a fuel cell hidden in the flooded chute below, then inserting it into a slot near the top to unlock a side room containing one of the four buttons.
The remaining three buttons are scattered unpredictably—some near staircases, others beside pipes, with one even lurking near the locked door itself. Assign each player to a button and press them all at once to unlock the first barrier. Beyond it lies the second door, which demands a mix of Metal Parts, Arc Powercells, Leaper Pulse Units, Motors, or Industrial Batteries—items that may require scavenging mid-match or bringing along beforehand.
Why It Matters
This puzzle isn’t just a gimmick—it’s a test of adaptability. The randomized repair requirements and button placements ensure no two attempts are the same. For players who thrive on unpredictability, it’s a fresh twist on Arc Raiders’* usual loot runs. However, those who prefer solo play may find themselves frustrated by the necessity of teaming up with strangers.
What’s Next?
The Controlled Access Zone adds depth to Dam Battlegrounds, encouraging players to explore beyond the usual hotspots. Whether you’re hunting for rare materials or simply chasing the thrill of a well-executed team effort, this puzzle is a standout feature of the latest update. Just don’t forget to bring friends—or at least a few spare Industrial Batteries—when you head in.
