The various mysteries you've experienced in Sons of the Forest will culminate in a harrowing journey to the very depths of the island. There, you'll face numerous threats as you attempt to make it out alive. Here's our guide to help you find the Golden Armor so you can unlock the Gold Arm Door in Sons of the Forest.

The Golden Armor and Gold Arm Door in Sons of the Forest

　　There's a larger-than-usual facility, and it's crawling with mutants. Check every room to grab some cool stuff here, such as the Putter, Leather Jacket, Katana, Gold Mask, and, of course, the Sons of the Forest Golden Armor.

The Gold Arm Door in the last facility

　　In any case, just go through each hallway and room until you come across a lounge where a corpse of a construction worker has been hanged. Peek inside the bathroom to see steam blowing out of an opening. Go through it and you'll find yourself in a cave system.

At the end of the passageway, you'll see the Sons of the Forest Gold Arm Door (as shown on the featured image). To open it, simply interact with it. If you already have the Golden Armor, then your character will don it automatically to unlock the doorway.

　　As you go deeper, you'll notice lava spewing from crevices. Likewise, there are dozens of mutants here just waiting for you. You could try to take them out with your Pistol, Shotgun, or Revolver, but there's just too many of them. However, if you previously acquired the Cross (in the same cave where you got the Rope Gun/Zipline Gun), you can use it to temporarily scare them. They'll still attack, but their melee strikes can be easily avoided. They'll also be somewhat hesitant, as opposed to being ultra-aggressive if you're wielding anything but the Cross.

Continue onward past numerous tunnels and lava-filled chambers and, eventually, you'll see another golden door. One of the soldiers is standing there and, if you move closer, a cutscene will play. This leads to one of several endings. We discuss these in our Sons of the Forest all endings guide.
