The grappling hook is an item in Green Hell that allows players to scale high ledges and access areas and locations that would otherwise be inaccessible. For example, there are climbing points on the map marked with the grappling hook icon, indicating where you would need to use it. This makes it quite an important item as it opens up some new options for you. The most confusing part of getting the grappling hook is that it spawns in two different places, depending on what game mode you’re playing. We’ll cover them both in this guide on how to get the grappling hook in Green Hell.

Where to find the grappling hook in Green Hell
Historical mode
In the Green Hell story mode, you will find the grappling hook in the illegal gold mines location. To get there, head north following the dirt road until you come across the overturned jeep. Loot the resources there and, more importantly, collect the red gas can. This will be important later.

Head east from the jeep until you come to a platform on a cliff. There is an electric lift there, but you need to recharge the generator that powers it. This is where the fuel you can pick up comes in. Use it then turn on the elevator to descend to the mining site. At the campsite, there is a bench on which the grappling hook rests.
survival mode
In Green Hell survival mode, it is much easier to find the grappling hook. Just like in story mode, find the dirt road and follow it north until you find the overturned jeep. This time you will find the grappling hook waiting for you there, among the other loot you can find there.
