Hey all! We are happy to announce that the PDFs for books 2-4 and their maps have all been distributed! We really appreciate your patience throughout this project. If you're having any issues at all, please send us an email at [email protected].
We wanted to share a quick update on where things stand.
The final PDF files are currently in the last stages of preparation. We're adding bookmarks, making final adjustments, and incorporating the feedback we've received from backers.
Thank you to everyone who took the time to submit errors and suggestions!
We will have the updated PDFs available this month.

We wanted to share a quick progress update because a lot is happening behind the scenes - and it’s the good kind of happening.
First up - Things are being made!
Collector’s Wooden Mimic Chest Lots of progress on the Mimic Box. This was always meant to be something worthy of holding the World’s Largest Dungeon, and we’re really happy with how it’s turning out.
🗿 Miniatures A little sneak peek of our Boss Monster Minis. The packaging is looking super slick, too!
📘 Coming Soon
Secret Doors PDF is nearly ready
Mini STLs are also close to release
Both are in final preparation and will be distributed shortly.
🖨️ Books Moving to Print
The World’s Largest Dungeon books are going to print!
We’re accepting final error reports through Sunday. After that, the print files will be locked. If you’ve found anything that needs correction, please submit it before then so we can include it in the final files.
