One of the challenges in Fortnite Chapter 2 Season 7 Week 4 is to collect a Doomsday Preppers guide. This is just a small book, and the map is quite large but lucky for you we have tracked down where it is.

To get your hands on the Doomsday Preppers Guide, you will need to make your way to Hydro 16, which can be found near the dam between Lazy Lake and Slurpy Swamp.

The Doomsday Preppers Guide can be found on the floor of an office in the southeast corner of the main building at Hydro 16. It is a blue book with a picture of a Llama n the front, and a pencil on the side. All you need to do is interact with it to pick it up.
