You're wandering through the dense, cannibal-infested woods of Site 2, and honestly, a wooden shack just isn't cutting it anymore. You want the cool stuff. I’m talking about the glider launchers, the gore chairs, and that ridiculous gold armor plating machine that feels like it belongs in a high-end laboratory rather than a survival nightmare. Locating all blueprints Sons of the Forest has hidden away isn't just about completionism; it’s about actually surviving the endgame when the mutants get faster and the nights get a lot darker.
Most players stumble upon the basic stuff. You find a note, you see a ghost-like outline in your guide book, and you build a log trap. Simple. But the "Special" blueprints? Those are tucked away in the back of pitch-black caves or hidden behind keycard doors you haven't even found yet.
The Essentials and Where They’re Hiding
Let's get real for a second. Some blueprints are basically useless unless you're trying to win a "weirdest base" competition. But others? You need them. The Glider Launcher is probably the single most important blueprint in the entire game if you value your time. Dragging logs is slow. Flying across the map is fast. You’ll find this one in a cave near the snowy mountain peaks, tucked away near some skeletons that clearly didn't know how to use it.
The Turtle Shell Rain Collector is old news, but have you found the Mannequin? It’s not just for aesthetics. It’s a way to store your armor sets so you aren't fumbling through that massive inventory mat while a Finger mutant is charging at your face. You’ll usually find these types of utility blueprints in the early-game bunkers, specifically the ones that look like abandoned maintenance hatches.

The Gore Furniture (Because Why Not?)
Endnight Games has a twisted sense of humor. They added a whole series of blueprints that let you decorate your home with, well, parts of your enemies. The Gore Chair and Gore Couch aren't just there to look edgy. They represent the descent into madness your character goes through. To find these, you’re going to have to dive into the deeper, more "fleshy" caves on the western side of the island.
- Bone Chair: Usually found in the earlier caves near the crash sites.
- The Chandelier: This one actually uses lightbulbs, making it one of the few high-tech lighting options that isn't just a torch stuck in a wall.
The High-Tech Blueprints You Might Miss
The Item Plating Downloader is the big one. This thing is a beast. You find it deep within the Luxury Bunker, and it allows you to coat your Ancient Armor in gold. It's a late-game requirement, basically. If you’re trying to finish the story without this, you’re making life way harder than it needs to be. The machine itself requires Solafite, that glowing ore you've probably seen sticking out of cave walls.
Speaking of Solafite, the Solafite Upgrader is another blueprint that changes the math of the game. It’s not just about defense; it’s about making your weapons actually hurt the endgame "puffy" variants.
Then there’s the Teleporter. Yeah, you heard that right. It’s not a traditional teleporter, but the Artifact pieces you collect throughout the game eventually function as a way to warp. Finding all the pieces is a grind, but the blueprint for the pedestal is located in the final golden cube room area. It’s the ultimate "I’ve beaten the island" flex.
Why Cave Navigation is Your Biggest Hurdle
Finding all blueprints Sons of the Forest offers requires you to embrace the darkness. Most people give up on the caves because they're confusing. Pro tip: follow the lights. Usually, the developers leave small lanterns or flare glows near the folders containing the blueprints.
The Knight V and the Hang Glider don't technically need blueprints to use, but the structures that support them—like the Glider Launch Pad—absolutely do. You’ll find the launch pad blueprint in a cave system near the southwest coast. It’s hidden behind a breakable wooden wall. If you aren't hitting every suspicious-looking plank with an axe, you're missing out on half the content.
The Weird Ones: Leg Lamp and More
If you’ve played The Forest, you know the devs love a good Easter egg. The Leg Lamp returns, and it’s just as creepy as before. These types of "discovery" blueprints are usually found in the residential areas of the bunkers. Look for the rooms that look like someone actually lived there—bedrooms, small kitchens, and office spaces. They are often sitting on desks next to laptops.

Making Sense of the Blueprints Page
Your survival book has a specific section for these. It’s the "Special" tab (the one with the gear icon). When you pick up a physical folder in the world, your character does a little animation, and then—boom—it's in the book.
Construction Tips for Blueprint Structures:
- The Spring Trap: Don't put it on a hill. It glitches. Put it on flat ground right in front of your spiked walls.
- The Spear Trap: These are great for narrow cave entrances if you're building a "safe house" inside a cavern.
- Electricity: Some blueprints, like the Solar Panel setups, require you to find the actual panels and wire first. The blueprint just shows you how to lay the wire along the logs.
The Power Drill and Chainsaw don't have blueprints, but the Battery Charger does. You’ll find the charger blueprint in the same bunker where you find the 3D printer. It's an absolute game-changer because scrounging for batteries in abandoned suitcases is a losing game.
The Truth About the "Missing" Blueprints
Sometimes you’ll see a ghost image in your book and think, "I've been everywhere, why can't I build this?" Usually, it's because you're missing a prerequisite. You can't build the Advanced Log Trap if you haven't mastered the basic log leaning mechanics. Also, some blueprints are locked behind specific patches. If you’re playing an older version of the game, half the cool Solafite stuff won't even be there. Always make sure your game is updated to the latest Steam build, because Endnight likes to stealth-drop new blueprints in random corners of the map without telling anyone.
Honestly, the hunt is the best part. Sure, you could use a map mod, but there’s a specific kind of dopamine hit you get when you see that yellow folder glowing on a desk in a room full of mutants. It feels like a prize. A very, very dangerous prize.
Actionable Next Steps
To actually get every single blueprint and stop living like a caveman, follow this sequence:
- Get the Rebreather and Rope Gun first. You can't reach 60% of the blueprints without these. They are the "keys" to the island.
- Focus on the Maintenance Bunkers. Use the GPS to find the green pulsing circles. Three of the most important structural blueprints are in Maintenance A, B, and C.
- Check the "Puffton" Bunker. This is the one with the gym and the nightclub. There are at least four decorative blueprints hidden in the side rooms of the VIP section.
- Mark your map. Once you find a blueprint cave, leave a GPS locator (purple icon) so you know you've cleared it. There’s nothing worse than backtracking through a cave you’ve already looted.
- Look up. In many of the newer caves added in 1.0 and beyond, blueprints are occasionally taped to the ceilings or hidden on high ledges you need the Grappling Hook to reach.
The island is huge, and the blueprints are tiny. Keep your flashlight charged, keep your axe ready, and stop ignoring the "boring" looking office buildings underground. That’s where the real treasure is.
