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

Latest Updates from Our Project:

Introducing The Unboxing of Isaac! Available NOW
3 months ago – Thu, Apr 07, 2022 at 01:22:43 AM

Hello Friends,

The most fan-requested merch during the Kickstarter was t-shirts… You asked, and we listened!!

We are excited to announce that Edmund McMillen & Maestro Media have teamed up to create a monthly subscription box called The Unboxing of Isaac

This new series features bold and creative The Binding of Isaac themed limited edition t-shirts, new Four Souls cards, and more. Featuring collaborations with well-known creators and artists like Tom Bunk, Daniel Shaw “sawblade666”, Jimbo Phillips, Angela Ho, Sr Pelo, and so many more.  These awesome new t-shirts will not be available ever again, so be sure to get your hands on all 12 while you can.

There are three ways to participate in The Unboxing of Isaac:

  • Subscribe to a recurring Monthly Subscription, for $30 a month and never worry about missing a box! We’ll automatically charge your card for the next month’s box, but don’t worry it can be canceled at any time. If you stay subscribed for all 12 months you'll receive 1 FREE box on the 13th month.
  • Purchase each month’s box individually for $35 per box. And pick and choose which shirts and boxes you want.
  • And coming soon: for a one-time Annual Subscription purchase of $350, reserve all 12 shirts+goodies & the bonus 13th shirt+goodies. This subscription will bundle every month together into one big box that will ship in May 2023! This option, available soon, should significantly cut down on shipping costs.

The first month's items!

At this time, we are not able to collect Taxes and duties and they may be due on arrival based on your location.

Watch the unboxing stream from the man himself here. He talks about the Annual Subscription around 9 minutes in, he starts talking about why he likes promo cards at around 19:30. You can also check out and print out this month's promo cards for yourself if you just want the cards at

The Pre-Order and Backerkit Stores are Back!
3 months ago – Wed, Mar 23, 2022 at 07:36:55 PM

Hello Friends,

Throughout the day we'll be sending out 50,000 individual emails so that everyone has a link back into their specific Pledge Manager. This will allow you to add items to your existing order. This is huge for a few reasons and we're thankful to our partners at Backerkit for helping make it happen! 1) You'll save on shipping, since everything will ship at once and in fewer boxes. 2) Everything in that order will ship out at the same time. If you make separate orders, they'll ship out separately, sometimes several weeks or more apart. If you have questions not answered below, please ask them in the comments section below! Now, let's answer some FAQs.

I haven't gotten my link yet!

Please be patient, it's going to take several hours to send out all of those emails. If you don't see it 12 hours from now, please check your SPAM folder before reaching out.

Who is the email from?

The email will be sent from

Can I upgrade my pledge level?

No, you'll not be able to do that yourself. If you would like to upgrade your pledge you'll need to message Please only contact Backerkit for upgrades to pledge levels. If you need anything else, please message

Can I change my address?

Absolutely, you've always been able to do that. If you click on the link provided in the email, skip over (or buy from) the add-on section and you'll get to the shipping section or confirm section. From there you'll see a button to "Edit Your Address."

Can I use a different credit card?

Absolutely, if you click on the link provided in the email, once you add-on your items you'll get to the shipping section or confirm section. From there you'll see a button to "Update Credit Card."

I don't want to add-on anything, do I need to do anything?

Nope, ignore the email that's coming from Backerkit. You've already been charged (or have been receiving emails saying your charge has failed please update your Credit Card) and will not see any new charges. This is just for those people who have expressed the desire to add more items after the original store closing in February.

Will the store open again?

No, this is it, the last time to add-on to your order before the game ships out. Any new pre-order store that opens will either be on our retail store or the retail version of the translated games from our localization partners and those versions won't ship out until much later and will not include the Birthday Card.

Does Requiem, The Big Boi Box, or The Full Collection include the Warp Zones/Alt Art/KS Bonus items?

If you are a Kickstarter Backer (someone who can comment on this Update in Kickstarter) your store will include the Kickstarter exclusives including Alt Art and Warp Zone cards, same as before. If you pre-ordered after July 3rd your items will not include any of the Kickstarter exclusives, same as before.

If I add more, when will I be charged?

Any add-ons will be charged when the store closes on March 31st. Expect most charges to happen on April 1 or April 2.

Is there a limit to what I can add-on?

No, go crazy. But also, we're announcing that secret project we were talking about in February in Early April, so don't go too crazy!

I used an email relay such as Apple Relay:

You will not have received any emails from Backerkit or Kickstarter, so hopefully you found this answer because you check the updates page. You'll need to email and let us know a different email address we can use to get you your link to Backerkit.

I might want to change my language:

Don't worry, you can still do that after March 31st. Once we have the cards translated we will show examples and give a deadline for when any language swaps will need to happen.

Things have changed and I need a refund:

Please email Just be patient, we realize that in some situations every penny helps, and we're moving through messages as quickly as possible. Please note, that with recent sanctions, every Credit Card company, PayPal, Venmo, Zelle, and other money apps has banned sending or refunding Russian backers. That might change later, but as of today all we can do is put the order on hold so it doesn't try to ship.

I didn't back the game but I want to pre-order:

You have until March 31st at 9am PST to do so, after that the pre-order store will close. We've had overwhelming demand and there's a limit to how much we can manufacture. 

Do Pre-orders include Kickstarter exclusives (Warp Zone Cards, Alt Art Cards, Gold Box Cards, etc)?

All of those were Kickstarter exclusives and are not available in the Pre-order Store. You are a pre-order backer if you ordered after July 3rd.

Is the Guardian Isaac Tier or Tapeworm Pink Box available for pre-order?

Much like the Warp Zones, those two items are Kickstarter exclusives and are not available in the pre-order store. They are available to Kickstarter backers as add-ons though.

I ordered two different pre-orders or a Kickstarter pledge and a pre-order:

You are welcome to do separate orders like that, just be aware that shipping will be more and separate orders are not guaranteed to ship together. If you'd like to combine orders please reach out to us at and we can assist you with combining orders into one. If you used multiple email addresses, please include any used in the email.

Will this store re-opening delay the release?

We're able to re-open the store because the manufacturer is able to do a larger print run without effecting the timeline. We are anticipating a few delays with the game being translated into multiple languages, the terrible conflict in Ukraine affecting global shipping, and recent shut downs in China as the coronavirus flairs back up (they've recently shut down the factories in the Shenzhen province and Shanghai Disneyland). When we have a better timeline we will update everyone, for now "late summer or early fall 2022" is the best guess we have. Again, we'll send an update when we know more.

This is also a great time to tell others that the game is available for pre-order since the store will only be open until March 31st at Noon PST (1900 UTC).

Thanks everyone!

The Pre-Order/Add-On Store Reopens For You NEXT WEEK!
3 months ago – Sat, Mar 19, 2022 at 04:30:01 AM

Hello Friends,

Several hundred of you messaged us in the past 6 weeks about missing the deadline to add on items to your existing Kickstarter Add-On or Pre-order purchase. We've heard you, and got confirmation that small increases in our print runs is doable without major delays in their timeline. You will be able to, starting on March 22nd at 9am PST, add items to your already locked Pre-Order (for people who didn't back during the Kickstarter) or Add-On Page (for Kickstarter Backers) pledges. We will email you next week with the details on how to do that!


  • If you already placed an order, whether during the Kickstarter or in the Pre-order store you will be able to add on to your order starting NEXT WEEK! 
  • On March 22nd you'll be able to add on to your existing order yourself. No assistance from Maestro Media or Backerkit needed. We will send out another update with exactly how to do that in a few days when your store opens up.
  • Until then, please do not message Backerkit or about adding stuff to your order, we're working diligently to make sure this goes smoothly for everyone and will be unable to add things for you. Most if not all of your questions will be answered in the next update which will come out on the 21st or 22nd.
  • You may see ads about the "pre-order store" being open now, while this is correct, it's for folks who have not already placed an order. If you place a new pre-order you will pay more in shipping and you will receive multiple shipments that could arrive several months apart. And if you were a Kickstarter Backer (i.e. someone who pledged between June 1 and July 1) if you pre-order anything right now you will not receive the Kickstarter perks. So again, please wait until March 22nd! For those Kickstarter backers, after March 22nd, almost all the Kickstarter exclusive stuff will be available again!
  •  DO NOT place a new pre-order at this time! Please, again, wait until March 22nd!
  • The Store will close again for good on March 31st at 9am PST. 
  • You'll be charged for anything added between March 31st and April 2nd. The charge will come from Maestro Media.

See you soon!

Card Approvals and Printing
4 months ago – Tue, Mar 08, 2022 at 04:47:27 AM

Hello Friends,

Our manufacturer has recently returned from Lunar New Year leave and has resumed work on Requiem! We received digital proofs for all cards just the other day and wanted to share the excitement with you!

In addition, Edmund went through and approved physical copies of the cards! Now we just need an offset set from the printer (and without the cut lines) before we move to full production!

One final note before we leave you.

Board games have always brought people together and transcended borders. We’re heartbroken at the violence and tragedy currently happening to the community in Ukraine. We hope for a peaceful resolution soon. Our thoughts are with all those affected by the conflict.

Our backers in Russia. We want to get this game to you, while ensuring money is not going the government. We will have to wait and see what we can and cannot do at the time of delivery. If we need to, we will hold delivery. If we have to, we will refund. If we can't refund due to banking sanctions we will look into other options. We've heard from several of you and you've expressed your anger over the conflict, please stay safe while doing so.

~The Maestro Team Updates
4 months ago – Mon, Feb 21, 2022 at 10:34:54 PM

Hello Friends,

While we're patiently waiting for manufacturing to spin back up next week and work out a more complete timeline for delivery, we've been hard at work updating We're happy to announce that those updates are now complete.

We've gotten tons of requests from people asking about differences between First Edition and Second Edition cards. Now you can check them out for yourself right on! When you click on the Cards link, you'll now see a section for Older Versions of the game.

We're another step closer to having a complete archive of every single card ever produced for the game! Check out some of the differences:

You'll also notice a couple of quick access buttons at the bottom of the page. Use these to quickly navigate to specific areas.

And did you notice the Accessibility icon? Now you can choose to turn off the background, switch into high-contrast mode, and change the font type as you like.

One other quick update, The Secret Project is being pushed back to April to ensure the quality of the project is perfect. We were just having this discussion on our Discord Server. While it's always a bummer when something is pushed back, we'd rather ensure quality over speed and a quick buck. Stay tuned, we'll announce the project as soon as it's ready!

That's all for now friends,

~The Maestro Team
