What To Do With The Greenhouse Key In Atomfall

In Atomfall, you’ll often come across locked doors all over the open world. Luckily, some of these doors can be opened, if you have the key for them. But, finding a key is a challenge on its own, and it’s super easy to get lost in this post-apocalyptic world.

Atomfall: Endings Guide

Atomfall’s ending depends on who you help and how you deal with Oberon.

Early on in your exploration, you might come across a couple of greenhouse huts in the Garden Centre area of the Casterfell Woods. While you can enter any of the greenhouse huts, there’s one that is locked and requires the Greenhouse Hut key to open.

How To Find The Greenhouse Hut Key

The Greenhouse Hut Key can be found inside the house, which is opposite the locked greenhouse hut. This house is on the other side of the road, and it’s hard to miss as it’s the only other prominent structure in the area, other than the greenhouse huts.

As you approach the house, you’ll find that wooden planks block the entrance to it, but you can crawl from on top of it to get inside. Make sure you’ve got healing items and a melee weapon because you’ll be encountering many rats in this area.

Even if you don’t have a weapon, you can aim at the ground and repeatedly press the Stomp button to get rid of the rats.

Make your way to the kitchen inside the house. You can get to the kitchen by going left from the entrance. Once inside the room, you’ll have to get rid of the rats, and after you do that, you can head to the room to your right. Go right again from here and you’ll end up in the kitchen.

After you’ve unlocked the door to the greenhouse hut, you can head inside it and you’ll find a letter. The letter is another lead for the Infiltrators investigation, and it mentions masked cultists roaming around and how a group of people is hiding behind the house.

You might find a few Druids roaming around here, so it’s best to be wary and have a weapon equipped to get rid of them quickly.

Now, the house in question is the same house that you had to go to get the key. This time, you’ll have to circle around the house to get behind it, and you’ll find a pathway that leads to the house’s cellar.

As you explore the cellar, you’ll find another letter, which will require you to head to the Skethermoor area as part of the Infiltrators investigation.
