Fortnite challenge guide: Collect doomsday preppers guide

Fortnite season 7, week 4 is underway, with a brand-new list of challenges for you to complete (and lots of XP to earn in the process). This new set of challenges is similar to last week’s — wherein almost all of them require you to visit specific, unmarked locations around the map. While these challenges aren’t necessarily hard, they can be tricky to get through if you don’t know where to go. One challenge in particular requires you to collect a doomsday preppers guide, as indicated by a blue book.

Since the game doesn’t specify where these are located, you might be stuck. In this guide, we’ll show you everything you’ll need to know about this challenge. Here’s where to collect a doomsday prepper guide in Fortnite.

There are two books around the map, but for the purposes of this challenge, you only need to find one of them. Since both spots aren’t normally very busy, you shouldn’t have much trouble running in and grabbing the book, but if you’re stuck, we recommend coming with a friend so they can watch your back. The map above (thanks, Fortnite.gg) shows the location of the doomsday preppers guide in Steamy Stacks.

It’s in the building marked number 03, just across from the large circular smokestack on the east side. Head inside this building on the bottom floor, and you’ll find the blue doomsday preppers guide on the ground next to a set of stairs. It’s on the east side of this building.

Alternatively, you can collect a doomsday preppers guide at Hydro 16, which is the dam area to the east of Slurpy Swamp. Head inside the east side of the large building from the south, and you’ll see a set of stairs. To the left of the stairs is a small room containing the book. It’s on the left, behind a yellow chair and next to a cabinet.

Remember, you only need to find one of the two doomsday preppers guides to complete this challenge. We recommend visiting whichever spot is closest to you in relation to the Battle Bus, as neither will be very busy for you after you jump out. If you’re having trouble getting to one before being eliminated, we recommend attempting this in Team Rumble mode. That way, you can respawn if you’re taken out. We also advise attempting this in a squad-based mode so you’ve got some protection as you hunt for the books.

After you’ve found one, you’ll earn credit for finishing the challenge, along with 30,000 XP for your troubles.

How to get Obsidian in Lego Fortnite
Lego characters mining a boulder.

Obsidian is almost as rare a resource in Lego Fortnite as it is in real life. This black, razor-sharp material can only be found in the most dangerous environments. That means knowing where to find it is only part of the trouble. The real test will be in preparing yourself to survive the trip. You'll also need the tools necessary to collect it. If you're ready to face the heat, here's how to get Obsidian in Lego Fortnite.
Where to find Obsidian

Obsidian is an ore, so if your first instinct was to look for Obsidian inside of caves, then you're on the right track. Unlike something like Marble, however, Obsidian isn't as common or in as easy to reach places. Obsidian will be found deep into caves near lava, but only caves found in a desert biome will have lava inside.

Every time Fortnite changes up the map, it becomes a whole new experience when checking out the new points of interest (POIs) and best places to land. With chapter 5 bringing some of the most dramatic changes in the map's history, a ton of secrets are out there on the island waiting to be discovered, such as a very lucrative cave. Those who have managed to wander into this hidden alcove have been rewarded with a huge stash of loot, making it a well-guarded secret among those in the know.
