Sons of the Forest’s island doesn’t just offer plenty of natural landmarks—it also hides countless secrets beneath the surface. Chief among them are hidden bunkers that are a major part of the story and reveal what’s really going on. If you’ve already cleared a few caves and maybe built a small base, it’s time to tackle the bunkers in the right order. You’ll find not only story clues but also rare items and tons of loot. In this guide, we’ll show you the optimal order, the keycards and items you need, and useful tips for each bunker.
Sons of the Forest bunkers: Gear and preparation before you head in
Don’t go in unprepared—tight corridors and tough mutants can end your run fast. Fights are cramped, so preparation matters.
Recommendations before your first bunker:
- Shovel: Required for most entrances.
- Light source: Flashlight (with batteries) or lighter.
- Healing & provisions: Medicine, food, and water for longer runs.
- Armor & weapons: At least Bone or Tech Armor, plus pistol/shotgun with ammo.
- Save point: Pitch a tent at the entrance for quick retries.
Tip: Explore the three main caves first to get key tools (e.g., the shovel). These guides help:
