10 months ago – Tue, Aug 12, 2025 at 02:00:02 PM

Book 4 Beta

Book 2 is still being edited, so we are moving along to Book 4. Watch your email for details! All backers should receive Book 4, and Book 3 and 4 Regional Maps.

Book 1 Beta is closed - Thank you, Delvers, for your over 130 comments! 
Book 3 Beta is staying open for a period of time since we are just now delivering the maps. 

FAQ

I didn't receive the beta content.
Check your email and spam filter for emails from [email protected]

Why didn't I receive a survey?
The 3 most common causes of this are (1) Your Backerkit email is not your main email, the survey will go to the email associated with your Backerkit account. (2) The email from Backerkit is in your spam folder. (3) You are using Pay-in-Four and it hasn't been sent yet.

Where do I report mistakes?

Surveys & Book 3 Beta!
11 months ago – Tue, Jul 29, 2025 at 06:12:23 AM

Surveys have gone out!

Anyone who is not using the Pay-in-Four feature will have received their survey this morning! Those of you who are still making payments will receive your surveys as soon as those are wrapped up.

Many of you are new to crowdfunding, and we're super grateful to have you here! So what are these surveys? This is a vital part of the crowdfunding process, where we gather important information from you, confirm your pledge, and so on. The key components are:
  • Confirming your order
  • Customizing your order with Add-ons
  • Giving us your shipping information
The surveys are required; we cannot deliver anything until they are done.

So please, take some time and fill out your survey! This ensures we can stay on schedule and get you your goods! 

Post Campaign Stretch Goals

In your survey, you will have an opportunity to customize your order. We have several add-ons available that were NOT in the campaign. The way these post-campaign stretch goals work is that if you add them to your pledge in the survey, or someone adds them in the pre-order store, it builds towards unlocking them for everyone! You will only be charged if the items are unlocked; if they are not, they will be removed from your cart.

These include Book 3 and Four of the Foundry VTT module, AND a massive pack of printed TACTICAL dungeon crawl maps. These differ from the included regional maps because these are actual 1x1-inch squares. Remember, this dungeon is MASSIVE.


Missed the Campaign? It's not too late!



World's Largest Dungeon Late Pledges are open!

Book 2 needed some additional time to gain experience and level up, so we are releasing Book 3 for the next phase of the Beta. Watch your email for details!

Book 1 Beta is closed - Thank you, Delvers, for your over 130 comments!

Smoke Tests, Update, and Book 1 Regional Maps
11 months ago – Tue, Jul 22, 2025 at 08:46:11 AM

It's a hefty update today! Here is a summary for all of the skimmers:

1 - Smoke Tests are going out TODAY
2 - Pre-Order Store has Launched!
3 - New Post Campaign Stretch Goals Announced!
4 - Book 1 REGIONAL Maps Beta are being released (Check the "Backer Only Content" Section at the bottom)
5 - Book 1 Beta continues, Book 2 Beta is planned for next week!

Smoke Tests

We have been hard at work developing the World's Largest Survey! This is a vital part of crowdfunding, where we collect information like your shipping address, confirm your pledge, and allow you to make adjustments to your add-ons.

A smoke test sends this survey to 5% of backers, allowing us to ensure everything is working properly before sending it to everyone. All you need to do is watch your email and follow the prompts.

If you are in the 5%, it's essential that you complete your survey promptly. We can't send the survey to everyone else until the smoke test is completed, so please take a moment to complete yours! All the delvers thank you!

Pre-Order Store has Launched!

You can view that here https://world-s-largest-dungeon.backerkit.com/hosted_preorders/

If you have already backed the project, this is of interest to you because of the new stretch goals we have added, and you may want to share with your friends!

The way these post-campaign stretch goals work is that if you add them to your pledge in the survey, or someone adds them in the pre-order store, and it builds towards unlocking them for everyone! You will only be charged if the items are unlocked; if they are not, they will be removed from your cart.

These include Book 3 and Four of the Foundry VTT module, AND a massive pack of printed TACTICAL dungeon crawl maps. These differ from the included regional maps because these are actual 1x1-inch squares. Remember, this dungeon is MASSIVE.



Beta Test Update! Book 1 REGIONAL Maps

If you are a backer, you received an email with the Book 1 Beta Test last week. Thank you to everyone who has participated! We've got about 150 comments so far that we are parsing through. Many of you requested the accompanying Book 1 Regional Maps, and those are included below in the backer-only section below.

We are on track to release Book 2 Beta next week! However, as always, please understand that quality will be our top priority, and these plans are subject to change. 

Thank you, everyone! Happy Delving! 

Beta Begins!
11 months ago – Tue, Jul 15, 2025 at 06:31:24 AM

Greetings Delvers! We are thrilled to release the Backer Feedback Draft of BOOK 1 of World's Largest Dungeon.

In order to keep things moving ahead at a good pace, we have emailed you access to the first beta. We had tried to move ahead with a much expedited survey phase, but we ran into a couple of technical blocks - mainly, the Pay-in-Four backers cannot enter the pledge manager until the funding is complete. To bypass that, we're sending out these beta deliverables via email.

Please check your email associated with your Backerkit account! 

Feedback for BOOK 1 is open for TWO WEEKS ONLY. We are accepting submissions starting NOW and through July 29th.

We will open similar two week feedback periods for further books, not necessarily in order, after Book 1 feedback closes.

Delivery of the final, print-quality, PDFs will occur closer to physical book delivery when our books are finalized and match their physical versions. We are aiming for September, but this could flex depending on how much is found during this beta phase. Quality will always come first.

The survey and late pledge/pre-order store is still in development and will be coming out soon. It's been slightly delayed due to a couple of aforementioned technical blockers. We'll update as soon as that is ready! 

Thank you!
