The Sons of the Forest rope gun allows you to string up ropes as ziplines, found in a monster-filled cave in the central island. It's a dangerous place to go, but if you want to progress, you'll NEED that rope gun, as the Sons of the Forest shovel, an integral progression item, requires both the rope gun and the Sons of the Forest Rebreather to access it. We can show you how to get all three, but be warned: it's not easy, and will require you to prepare well in advance if you don't want to be dependent on luck. Bring your best weapons, and a tarp/sticks so you can set regular saves along the way. If it comes down to it, run! Hitting a narrow tunnel is (usually) the point where monsters stop following you, though sometimes you might not be so lucky. With all that in mind, and with your pack stuffed with ammo and blunt objects, let's go and get the Sons of the Forest rope gun and get you more mobile around the island.
1. Find the Sons of the Forest rope gun in this cave
The rope gun is in a cave near the helicopter where you crashed so head to the area shown on the map. You're looking for a boarded up cave recessed into the cliff with a couple of crates outside.
If you can, build a simple wooden shelter outside so you can save. Keep your tarps to build shelters to save inside the cave, as it'll make life easier if you can avoid trying to run the whole thing in one go.
Smash the boards with any weapon you have and head in.
2. Head left once inside the cave
Once inside you'll be in a linear tunnel initially so scoop up supplies you find and keep head forward. Eventually you'll reach a lit lower cave you can get down to using a path on the right side of the edge.
Once you're down the safest thing to do is hug the left wall and follow it around until you find a narrow corridor leading out. There are basic enemies here but you really want to avoid them as much as you cannas it can quickly get out of control in the open space. The narrow corridor will lead you into a chamber blocked by a monster.
3. Use the time bomb to blow up the monster
The monster is stuck and blocking the way forward, but can't hurt you so this is a good place to set up a shelter to save at - the section ahead is long but quite straight so it's easy to keep heading back and saving your progress.
Pick up the two bombs to the right of the creature next to the body, and use one to blow it up. You can now head through.
The next area ahead will be a straight tunnel into another open lit cave. There are some basic enemies in here but also a finger (an enemy that is just a giant mouth on legs). You can fight them using the narrow entrance area as a useful choke point and a good area to use molotovs if you have any. But you can also sneak or run by them. Past that area you'll reach a space with some bodies hanging from the ceiling and cave painting.
4. Move past the cave painting and run if you have to
There's a Twins enemy here so again sneak or run past if you can, and keep going. You'll come to another lit up area with bodies hanging from the ceiling and this time there will be some baby enemies. These aren't too hard to take on as long you strafe to avoid their jumping attack and hit them when they land. There's quite a few though so it can go south fast.
You'll eventually hit another narrow section and when you come out into another lit area you might want to stealth as far as you can, then run the second it you're spotted. There's a lot of enemies in here, including fingers, and it's tough to fight them all. You'll know when you reach the end as there will be a light shining out over the exit.
5. The Sons of the Forest rope gun location is left at the shiny rocks
This is the last stretch: another corridor with some baby enemies to deal with or run past. You'll pass some more hanging bodies and light but the thing to look out for is a left turn, framed by some metallic rocks, with some bone piles inside.
If you go straight on at this point you'll find a few items and a dead end. Do that if you want and then go back and take the turning. When you turn left there's a long straight path to the Sons of the Forest rope gun. There will be some baby monsters along the way you can stealth, fight, or just run past. Eventually you'll see a lit dead end with the rope gun in a crate.
Pick up the rope gun up and you'll be able to use the rope you can see above with the cloth hanging on it to get out. Once you land, just run. You'll pass a twins enemy but if you keep going you'll hit the exit and can escape with no trouble.
