Production Update: Mimic Chests, Audiobooks, and What's Next
Hey everyone!
We have some great production news to share about The World's Largest Dungeon: 20th Anniversary Platinum Edition, along with an announcement about what's coming next!
Production Update: Everything Is Moving!
We're getting closer to fulfillment! All production samples have arrived, and everything still on the way to our warehouse is currently on the water.
We look forward to getting everything into your hands, and we appreciate your patience as we work through the final stages of production and shipping. Here's a peek of everything.
The Mimic Chests Have Arrived!
Due to their size, the Mimic Chests will ship separately from the rest of your rewards. This also means we can start shipping them earlier, rather than waiting for the remaining campaign items to arrive.
Keep in mind that your Mimic Chest and the rest of your rewards will arrive in separate shipments.
The Audiobook Is Complete!
We've also got an exciting update from AudioRPG.
The World's Largest Dungeon audiobook is officially finished and ready for distribution!
Announcing Forgotten Chambers: Beyond the World's Largest Dungeon!
Some extraplanar prisoners were considered so dangerous that the celestials refused to connect their cells to the World's Largest Dungeon. Instead, they scattered their chambers and hid them throughout the world.
Forgotten Chambers sends adventurers to these isolated prisons to confront the creatures held within and uncover the secrets and treasures left behind.
The new campaign includes:
A 200+ page adventure book for 5E
A 40-page lay-flat battle map book
A professionally narrated audiobook from AudioRPG
And the adventure doesn't stop there! Forgotten Chambers will also lead into The World's Largest City, continuing to expand the world beyond the original dungeon.
We have some good production news to share today: the dice have arrived!
📦 Production Update
The Mimic Chests are on the water and making their way toward the warehouse, while the World’s Largest Dungeon books are currently printing.
We’re hoping to have a more definitive production and fulfillment timeline from the warehouse soon. As soon as we have dates we're confident sharing, we’ll pass them along to everyone.
🔒 Orders Are Locking Today
Now that the pre-order store has closed, orders are being locked today.
If you added any additional items to your pledge after the campaign or placed a pre-order through the store, those charges will also be processed as orders are finalized.
Please keep an eye on your payment method and BackerKit account in case anything needs your attention.
Things are moving along, and we appreciate your continued patience as all of these pieces come together. We’ll share more production updates soon!
First off, thank you to everyone who stopped by our booth at Gen Con! We had a great week and got to meet quite a few of our backers. Now that the dust of Gen Con is settled, we wanted to give you a little production preview.
We've received a video from the manufacturer showing the miniature packaging in production!
Things continue to move forward, and we'll keep sharing updates as we receive them.
Thanks again for your continued patience and support. We can't wait to get everything into your hands!
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].
