If you’ve been taking your time exploring Casterfell Woods in Atomfall, it’s likely that you’ve ran into the Garden Centre, where there are multiple greenhouses to loot. That said, there is one locked Greenhouse Hut here that you won’t be able to access without tracking down the Greenhouse Hut Key first.
Fortunately, as is usually the case with Atomfall’s keys, the Greenhouse Hut Key is just a short walk away from the hut itself. It’s just very well-hidden and easily ran past, but to help make sure you don’t miss out on it, here’s where to find and use the Greenhouse Hut Key in Atomfall.
Where to find and use the Greenhouse Hut Key in Atomfall
If you’re looking for the Greenhouse Hut Key, the likelihood is that you may have already found the locked Greenhouse Hut in the Garden Centre of Casterfell Woods in Atomfall. If you’re yet to track that down, we’ve marked it on the below map:
In the Garden Centre area, you should also see a large barred-up house. This is where the Greenhouse Hut Key has been hidden.
It might look like the house is inaccessible, but if you approach the front door, you can actually climb over the wooden planks here and head on inside.
Once inside the house, you will find the Greenhouse Hut Key hanging from a shelf in the kitchen, just above one of the kitchen counters. Much like the Castle Key in the Druid’s Castle Ruins, it can be very easy to run past this Key, so keep an eye out for it.
With the Greenhouse Hut Key in your possession, you can return to the Greenhouse Hut and unlock it.
Inside the Greenhouse Hut, you will find some crafting supplies and the ‘We Are Waiting For You’ letter that gives you a lead for the Infiltrators quest. It also mentions some folk are hiding out behind the house, hoping that Agravaine – someone we can assume to be the Infiltrators leader of sorts – may have sent someone to help them.
If you do as the letter advises and go behind the house where you acquired the Key from next, you’ll find a cellar. Inside the cellar, you’ll find even more crafting supplies and some ammunition, as well as more notes.
‘The Special Operation Has Failed’ note explains that Agravaine’s agents – who are here investigating the Windscale disaster – have been trapped. A second note, ‘The World Has Gone Mad’, explains an agent’s unfortunate run-in with the Druids.
In the final room of the cellar, you’ll find a BARD Crate containing a Training Stimulant, and one final note titled ‘I Can Hear the Voice’. This explains that one of the agents presumably became infected and began hearing the voices in the soil, and gives you a lead suggesting that you search Brinsop Manor Ruins in Skethermoor for more evidence of Agravaine’s infiltrators.
