Green Hell - How to Find The Cure (End Game Hint Guide)

This hint-only guide aims to help you figure out the ending on your own, without spoilers. The goal is to allow you to maximize the amount that you figure out on your own. It’s done in the fashion of old Universal Hint System guides, offering increasingly more direct hints.

Introduction and Purpose

All credit goes to Dogsbody !

Green Hell doesn’t tell you much, and that’s a big part of why it’s fun: figuring things out for yourself, and eventually mastering them so that you can walk around practically fearlessly in a world that was previously a nightmare. It is Nietzschean overcoming at its best.

But it tells you even less about how you can find the cure and get the good ending in Story Mode. Many people (perhaps most?) will end up spoiling the ending to a great game for themselves out of frustration, especially as the bad ending is so terrible. That’s what happened to me, and it was … quite disappointing.

So, this hint-only guide aims to help you to the ending without spoilers, but also, to allow you to maximize the amount that you figure out on your own. It’s done in the fashion of old Universal Hint System guides, offering increasingly more direct hints.

Warning: The final hint does still provide the solution.

Hint-Based Guide

Let’s find the cure, Doc.

To maximize your satisfaction, look at each hint in order and think about it before moving on to the next.

Only when you’re truly stumped (or already knew what the hint told you) should you go on to the next one.

Make sure you have the mission objective to find a cure in your notebook. That’s when you need to start worrying about this. Considering how elusive the cure is, however, if you haven’t gotten there yet, you might want to start taking notes on game lore beyond what is automatically recorded in your notebook.
You will only be able to create the cure in a specific location. That location will be obvious once you have found it.
Have you discovered Omega Camp? If not, continue until you have. (You may need to take a dive at the place where you found diving equipment.)
Have you fully investigated Omega Camp? It’s not immediately obvious, but there is a second entrance aside from the holes in one tent.
Find the closed flap on the intact tent and interact with it to open it and go inside.
You will need to synthesize the cure using the device in this laboratory tent.
First you will need infected blood to test cures against.
Find infected blood in the refrigerator in the tent. Insert it into the device.
Now you will need a sample. Insert samples into the device to test if they are the cure.
Through process of elimination, you could find the cure by inserting every item in the game in every state. However, you could narrow things down through a little detective work.
Have you listened to all audio recordings in the camp for ideas?
The audio recordings tell you about what was already tried and didn’t work. You can cross those items off your list.
If you recall, the game revealed that the natives are immune to the disease. Why do you think this is?
Is there anything different about what the natives have experienced?
If you can’t find the answer, it may be worth revisiting the final sequence and getting the bad ending again.
There is a hint in that ending.
There is an identical, subtle hint that is found both in the game’s introduction and in the final sequence.
The subtle hint is not in any of the dialogue with Mia.
The scientists’ research seems to have focused heavily on flora samples (plants).
In your visions, do you remember hearing, “The children are the key”?
What information do you remember about the children of the tribe?
You follow them in the ayahuasca rituals. Where else have you seen them mentioned in the game?
The children are mentioned in Higgins’ tent in the introduction/tutorial and final sequence, pinned to a corkboard.
The paper details a ritual the children undergo.
The children are tattooed.
The tattoos are used to create an immunity.
Poison dart frogs are used in a tattoo to create a natural immunity to the frogs’ poison.
If they possess this posion immunity and also immunity to the disease, perhaps these things are related? (…However implausible this is from an actual biological perspective.) Have you tried testing such as frog as the sample for the cure?
Huh, it didn’t work?! Is there any special condition for how the poison is used?
Did you ever create poison darts using a frog stretcher?
Or maybe go check that corkboard again in the bad ending. Read it carefully.
There’s a difference between how you used the frog in the sample versus how the natives use the frogs in the tattooing of the children and how they’re used in the creation of poison darts.
There are multiple states for animals to exist in, even when in your inventory.
The state you need the frog to be in may be especially painful. You might even die if you don’t come prepared.
