The Binding of Isaac: Four Souls Requiem

Created by Edmund McMillen

Update: Preorders open again until March 31 or until we sell out again -- whichever comes first! After selling out on our initial preorders, we've since secured another small print run of Four Souls Requiem. Only pre-ordered copies of the game come with an exclusive 10th Anniversary Isaac card. Pre-order the retail version of The Binding of Isaac: Four Souls Requiem and the add-ons from the original Kickstarter campaign. All orders placed now will ship in Fall 2022. Please note that we are still finalizing the design of some of our products and there may be subtle differences between the items shown here and the final products. Credit card charges will appear as: Maestro Media

Backerkit Questions
10 months ago – Thu, Aug 19, 2021 at 02:25:36 AM

Hello Friends,

What a great 2.5 weeks it has been. We've spoken with thousands of backers who have had questions about Backerkit. Thank you for your patience as we worked through all of the emails.

  • 80% of backers have already filled out their pledge, thank you! If you haven't filled it out, please make sure you do soon.
  • All surveys have been sent out. If you haven't received yours please check out your Junk Folder. You can also try to recover your Backerkit email by heading to: If you still can't find your pledge, please reach out to

Early Bird Figure

One of the most asked questions was about the Early Bird Figure. It's showing up in Pledge Items on your Confirmation Page, not in the add-ons like you'd expect it to be. It also doesn't necessarily show up until step 3 or 4 of the Backerkit Survey.

Corrupted Data & Ultra Pride Pre-commit Cards

Another question we've been getting is about the Corrupted Data and Ultra Pride cards. These were for folks who pre-committed to the Kickstarter by signing up with their email before June 1st. If you pre-committed with one email and your Kickstarter email is different, please message and let them know both of your email addresses so we can verify and get the cards added. If you change your Tier in Backerkit, the two cards will disappear. This is an easy fix by messaging the Help Center, just make sure you change your pledge to whichever tier you'd like first since they'll disappear anytime you change your pledge level, just message us after!

Coins & Dice Clarification

The Big Boi and above tiers will include the 100 Tainted Coins and the upgraded Isaac Face D6 die only. This has been asked in the comments so we wanted to make sure to clear it up.

NSFW Tapeworm

The last announcement for tonight: the NSFW version of Tapeworm, the never to be sold again Kickstarter Exclusive will be dropping in Backerkit in the next week or so! I will send another update out about the exact timing of the launch soon. If you have already completed your survey, there are a few steps you'll want to take to ensure you can quickly and easily get back to the add-ons section. I will have a how-to in the next update so don't fret! 

I did a few test runs. It is quicker to get back to check out and lock in your copy if you have already completed the survey.

 Back soon!
