Navigate the dangerous Maintenance Bunkers in Sons of the Forest to find keycards and advanced gear. Prepare for mutated inhabitants and crucial story progress.
Bunkers are underground structures marked by white and green circles on your GPS. These bunkers contain multiple rooms and valuable items, but often require keycards for full access. One bunker, near the Survival Raft quest marker, houses a 3D Printer and a door requiring a Maintenance Keycard. Beyond this door, you'll encounter mutants, loot, and the Guitar. The Guest Keycard, essential for accessing all areas within this bunker, can also be found here, leading to the Shotgun Rail and Electric Chainsaw. The location of Maintenance Bunker B is also accessible from this bunker.
Another bunker contains food items and a door that needs either a Maintenance or Guest Keycard. Inside, you'll find a hydroponic farm and more mutants. The Crossbow is located in the middle of this area. To proceed through the final door, you will need the VIP Keycard, which is also found within this bunker.
