Smoke Tests, Update, and Book 1 Regional Maps
8 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!
8 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!

We did it! Thank you Delvers. So, What's Next?

Thank you all so much for your support. Our backer train ended VERY LATE Friday (See: Early Saturday), and when the bell rang, we raised $1,021,783 with 2,435 backers. That makes us the 10th most funded Backerkit campaign of all time, and the 3rd biggest Role-playing game project on Backerkit!

Huge thanks to all of you for your incredible support.

What's Next?

The campaign will gradually wrap up over the next couple of weeks as cards are charged and backers are given the chance to correct any bank alerts or failed payments.

Then we'll move into the Survey Phase. This is where you'll get an email that asks for your information and allows you to add add-ons and manage your pledge. It's a big campaign, with a lot of pieces, and a big job, but we started working on the Surveys over the weekend, and plan to get those out as quickly as we can finish them and Backerkit allows!

As soon as the survey is complete, the beta will begin! Stay tuned for more information and updates!
