Unlocking the sealed golden door represents the ultimate challenge in Sons of the Forest, requiring strategic preparation and precise navigation through dangerous territories. Your journey through the island’s mysteries culminates in a perilous descent into subterranean depths where survival depends on both combat skills and puzzle-solving abilities.
The various enigmas you’ve encountered throughout Sons of the Forest converge into a harrowing expedition to the island’s deepest regions. Here, you’ll confront multiple threats while attempting to escape with your life. This comprehensive guide details the exact steps to locate the Golden Armor and subsequently access the Gold Arm Door in Sons of the Forest.
Securing the Golden Armor in Sons of the Forest demands obtaining three specific access cards in this exact sequence: Maintenance Keycard, VIP Keycard, and finally Guest Keycard. Each card unlocks progressively restricted areas, so skipping any will block your progress completely.
Once you possess all three keycards, proceed to the island’s opposite shoreline. Regardless of GPS Tracker map orientation, navigate toward the mountain range’s far side where a distinctive green marker appears adjacent to both a cavern entrance and body of water.
You’ll discover an unusually large complex teeming with hostile mutants. Methodically search each chamber to secure valuable equipment including the Putter, Leather Jacket, Katana, Gold Mask, and crucially, the Sons of the Forest Golden Armor itself.
Left: The facility containing Golden Armor, Katana, and additional treasures; Right: The Golden Armor positioned within one chamber.
Pro Tip: The Katana proves exceptionally effective against mutants in close quarters, while the Gold Mask may provide unexpected defensive benefits against certain enemy types.
After securing the Golden Armor, follow the coastline while remaining on the distant island shore. You’ll encounter another green waypoint marker. Enter the tunnel opening and advance deeper into the facility complex. This area closely resembles your previously visited location but contains no additional unique collectibles.
Navigate through corridors and chambers systematically until reaching a lounge area featuring a suspended construction worker corpse. Inspect the bathroom to locate steam emerging from an aperture. Traverse this opening to enter an extensive cave network.
Left: The facility housing the Gold Arm Door; Right: Examine the bathroom upon reaching the lounge with the suspended individual.
At the tunnel’s terminus, you’ll encounter the Sons of the Forest Gold Arm Door (displayed in the featured image). Activate it through interaction. If you’ve obtained the Golden Armor, your character will automatically equip it to unlock the entrance.
As you penetrate deeper, observe molten rock erupting from fissures. Additionally, numerous mutants await your arrival in these chambers. While engaging them with firearms like Pistol, Shotgun, or Revolver remains possible, their overwhelming numbers present significant challenges.
However, if you previously secured the Cross (located in the same cavern where you obtained the Rope Gun/Zipline Gun), deploy it to momentarily intimidate these creatures. They’ll continue attacking, but their close-range assaults become easily evadable. Their aggression level diminishes considerably compared to encounters where you wield any weapon except the Cross.
Left: Utilize the Cross to frighten mutants; Right: The subsequent golden doorway guides you toward your adventure’s conclusion.
Advanced Strategy: Combine the Cross with hit-and-run tactics—activate the Cross to create space, attack vulnerable mutants, then retreat while the deterrent remains active. This approach maximizes survival chances in these hazardous final chambers.
