Navigating the treacherous island in Sons of the Forest requires more than basic survival skills, as the most valuable gear is hidden deep underground inside sealed bunkers. These subterranean shelters contain story items, high-tech tools, and critical keycards needed to progress through the narrative. Locating these structures and understanding what lies inside is essential for any player attempting to survive and escape.
Maintenance Bunkers A, B, and C
The Maintenance Bunkers are hidden underground sites that typically require a shovel to dig up their access hatches. Inside Maintenance A, players can find the vital Maintenance Keycard, a 3D printer, and the Firefighter Axe. Maintenance B and C contain additional equipment, including weapons like the revolver and useful crafting supplies.
Food and Entertainment Bunkers
Located on the western side of the island, the Food and Dining Bunker and the Entertainment Bunker serve as major progression hubs. The Food Bunker houses the VIP Keycard along with various consumables and weapons. Meanwhile, the Entertainment Bunker contains the Guest Keycard, 3D printing equipment, and key weapons such as the chainsaw and guitar.
Residential and Ruined Bunkers
Accessing the Residential Bunker requires using the Guest Keycard found earlier in your journey. This bunker holds iconic gear like the Katana and provides further insights into the backstory of the island's inhabitants. The Ruined Bunker, on the other hand, poses extreme combat challenges due to dangerous mutant encounters while shielding valuable weapons and attachments.
The Final VIP Bunker
The VIP Bunker is the culmination of your island exploration and represents the point of no return for the story. Reaching this endgame location requires gathering all necessary keycards and preparing for intense endgame hazards. Inside lies the resolution to the island's mysteries and the final steps needed to reach the story's ending.
