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

Lilith and New Card Reveals Inside!
over 2 years ago – Sat, Sep 25, 2021 at 04:19:39 AM

Hello Friends,

The production team has been extremely busy behind the scenes and we wanted to share the progress with you. September is extremely busy on deliverables. Templates for the boxes are being finalized, the cards are getting the finishing touches and we should be showing you them soon! We received the final prototype for Lilith!

More Card Reveals

It's been awhile since we've shown off some card art. We miss having cool reveals to talk about. WE'RE CHANGING THAT RIGHT NOW! First off, we're extremely pleased to announce our new Alt Art Card from none other than MeatCanyon! Click on that link to check out his insane and NSFW YouTube channel.

Second, during the final boss fight, when you all defeated The Beast in epic combat! In the livestream Dice Roll 1! Edmund rolled a 19. We were all tired, things were said, promises were made and somehow people thought that meant that we could make a Darkest Dungeon Warp Zone a reality...

Well we did it dammit! The Collector from Darkest Dungeon is now a part of the Binding of Isaac: Four Souls Warp Zone collection and is exclusive for you.

The train keeps rolling, Isaac is ALMOST 10 Years old! We'll be back soon with even more goodies to show off soon. 

Backerkit Will Charge Cards September 30th-October 2

Just another reminder that Backerkit will lock orders on September 30th and card will be charged the 48 hours following that. Don't worry though, if you'd like to purchase add-ons after September 30th, it's as simple as reaching out to the Backerkit team ( and requesting they unlock your pledge. And if you change addresses between now and the game shipping, don't worry, we'll be sending out a last call for address changes email right before we give that info to the Fulfillment Centers.

Big Boi White Box
over 2 years ago – Tue, Sep 21, 2021 at 02:31:15 AM

Hello Friends,

It's about to get nerdy up in here, you've been warned! Designing a game is never a straight A-B line, everyone works a little bit differently. We could go on about designing games, but there's already a ton of really good information out there. If you're interested in learning more, I highly recommend the books of Geoffrey Engelstein, the blogs of Ignacy Trzewiczek or Jamey Stegmaier, and the website

One staple of any design process is the White Box Test. This is the first time we get to see our game start to come together. The manufacturer will send us a completely blank version of the game, the box, or both so we can make sure the game is as we envisioned. This week we got to see the White Box of the Big Boi Box. We've not made a hinged box before so this was an important test to ensure the box looks good and does what we want it to do. I'm happy to say it does both. And it's rugged. But don't take my word for it:

This does not include the latch that we designed before the Kickstarter started to make sure that there was a way to keep the box closed. Don't worry, it will all be combined when they give us a prototype of the game. We're one step closer to this little beauty being a reality:

Speaking of the Big Boi Box. Our current plan is to sleeve the box and add the game logo, pictures, description, and all the legal mumbo jumbo to the sleeve. That way your box remains an epic treasure chest. This sleeve will also be translated so those of you who bought the game in different languages will know exactly which game is which.


Just a reminder to everyone that Backerkit locks on 30 September and cards will be charged the 48 hours following that. We realize that between now and delivery of the game that addresses will change, we will send out an email on how to change addresses if needed closer to the delivery date, so don’t worry. If you would like to purchase more items after Backerkit locks, it’s as simple as reaching out to the Backerkit team ( and requesting they unlock your pledge. This is especially relevant for the folks that want to spread the charges out over several billing statements so we wanted to make it as simple as possible.

If you’d like to make any last minute changes to your Backerkit order, you can either use the email link provided earlier, or head here to find your survey again.


The game will be finished in October and will be ready to send to the manufacturer. The artwork and wording on all of the cards are going through final tweaking and there will be a few weeks of playtesting and card clarity.

This also means that we will not have examples of the translated cards before Backerkit locks on September 30th. We're aware there are people waiting to make a decision about the language preference based on these examples. We've worked with Backerkit to create an easy fix. In a few months when we show you the translated cards you can head over to and ask them to update the language if you decide it needs changed. Don't worry, you don't need to remember this link, when we show you the cards we'll include it.

We'll be back with more soon,
