Unraveling the Mystery of Sons of the Forest‘s Golden Arm Door
The Golden Arm Door marks the climactic end to your harrowing journey through Sons of the Forest. This bizarre, severed arm-shaped door blocks the way forward to the game‘s final confrontation. To progress, players must locate special keys to unlock its secrets.
As a professional gamer who has completed this challenge, I can attest conquering this mystical door is no easy feat. But with grit, wit, and the right preparations, you too can discover what lies beyond this gate. This guide will equip you to take on Sons of the Forest’s tense endgame.
A Perilous Final Test
Game director Farket revealed the Golden Arm Door was designed as the last significant obstacle before the player‘s escape from the island.
"We wanted to challenge players leading up to the finale with a multidimensional, Zelda-like quest focused on problem-solving under pressure,” Farket said in a Reddit AMA. “The Arm Door and its two locks force you to explore the island’s depths while overcoming combat, traversal, and inventory management challenges."
The door itself resides deep within the concrete bowels of a seaside bunker complex on the eastern shores. Behind its limbs rests the means to end your tribulations.

But breaching its defenses requires retrieving two rare keys: the Maintenance Keycard, and Golden Armor. Securing these will demand extensive underground exploration amid lethal adversaries.
You must steel your nerves and stock your arsenal if you hope to unveil the secrets beyond its grip.
retrieving the Bunker Access Keycard
Your first goal is to seize the Maintenance Keycard – this pass grants access to the bunker actually containing the Arm Door itself.
Consult your GPS locator to identify the green map marker indicating the keycard‘s subterranean cache in the northeast region. Bring a shovel to unearth this buried lockbox under the soil.

Quickly stash the retrieved keycard to utilize soon. It paves your way into numerous bunkers housing critical gear for progression such as the essential Golden Armor.

With this keycard in hand, the first barrier before the Arm Door lifts. Now begins the dangerous trek towards acquiring your mystic key – the Golden Armor.
Braving the Perils of the Golden Armor Bunker
The exceptional Golden Armor generates not just protection but also catalyzes the door’s opening. This radiant plate mail sits primed for the taking within a small bunker to the southeast…but breaching its walls endangers your life.
Horrific abhumans and warped mutants stalk these halls. Descend prepared with weapons, ammo, molotovs, and medkits lest you perish and lose this priceless prize.

Utilize your Maintenance Keycard to gain entry into the first level. Fighting through, descend stairs to the second basement floor. In a room therein lies a regal couch; resting atop it glows the Golden Armor in all its splendor.
