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:

First Time Backers | More Alt Art Cards | Warp Zone
over 2 years ago – Fri, Jun 11, 2021 at 12:35:41 AM

Hello Friends,

There are over 20,000 backers who are new to an Edmund McMillen Kickstarter and just under half of that number are brand new to Kickstarter. Welcome, and thank you for trusting us to be your first! This update is to help explain the Kickstarter and Backerkit process. If you just want to see some cool unlocks from the last few days, scroll down to the Campaign Updates Section.


Kickstarter is a marketplace where people can pledge to help make a project a reality. For our game you’re helping raise money so we can get the games printed and merchandise made. During the 31 days of the Kickstarter, the more backers and pledges we get, the more we can add into the game. This is known as a STRETCH GOAL. Stretch goals for Four Souls include Alt Art Cards (cards reimagined by visiting artists) which get added every 1000 backers, Warp Zone Cards (cards from other popular video games) which get added when social challenges are completed, and financial/backer goals when specific milestones are hit. To be clear, the game does not yet exist, your pledge helps us make the game a reality!

Once the Kickstarter ends, your pledge will be collected.


A few weeks after the Kickstarter ends, an email will be sent out from Backerkit. This is an important email to be looking out for! Backerkit is a “pledge manager” and is where you can purchase add-ons. If you added bonus support during the campaign, this extra money will show up in the Backerkit and acts as a credit when selecting add-ons. This is also where you’ll enter your address and pay for shipping fees and Taxes/VAT as required by your state or country. The Backerkit will remain open for several months until the games get close to fulfillment. You will be able to make changes to your address until we lock the Backerkit. Our shipping estimate for backers to receive their items is June 2022.

Do you have any questions about the process or how Kickstarter or Backerkit works for this game? Let us know in the comments below. And if this is your first Kickstarter, we’d love to hear from you! Let us know in the comments below what brought you to the Kickstarter and what you’re most excited about!

Campaign News

We held off on unlocks yesterday to focus on the translation news. But we’re back with a vengeance today!

You’ve unlocked even more Alt Art Cards! These are redesigned cards from different artists. One is added to the game for every 1000 backers! These Alt Art Cards are in addition to the cards that are included in the game.

On the Social Goal Side, you’ve now crushed both the Ashpit & Gehenna Social Challenges, completing SEVEN challenges now in ten days.

Up next and live now is The Corpse:

By completing the Ashpit & Gehenna you unlocked the next Warp Zones. Warp Zones are characters, items, and monsters from other creators that have warped into Binding of Isaac: Four Souls. These crossovers add brand new and exclusive cards to the game! Welcome to the Warp Zone:

Remember, Update #6 is where we want to hear your Warp Zone suggestions!

Lilith Plush & Nuclear Throne Warp Zone
over 2 years ago – Thu, Jun 10, 2021 at 03:43:46 AM

Welcome to Week 2 Friends,

We’ve got a lot to talk about this week but let’s start with some big news on the Plush Front. We started prototyping plushes all the way back in March and we loved the look of Blue Baby and rerelease of Azazel. But something wasn’t right about Lilith. And then we realized, SHE WAS MISSING EYES under her blindfold and Incubus was missing! So it was back to the shop to work on those. That’s why you see a 2D mock up of her in the Add-on section. Well, we have some great news, and we’re sharing it here first. Lilith is back! And she’s ready for action:

Look at those eyes! Look at the blood! Look at that hair! She’s going to be an epic addition to our collection, but that's not all. Incubus isn't just hanging out in that picture for fun, IT COMES WITH LILITH!

Is there any other merch you'd like to see featured in an update? Let us know, and we'll get a nice big picture prepared for you.

Campaign News

We’ll be updating just about every other day now but you all keep impressing us with how quickly you finish these Social Challenges. Thank you for your suggestions on future Warp Zones you’d love to see, we’re having a couple of very interesting conversations with people. I’m a bit behind on reveals, but I wanted to call out a Warp Zone we showed off in the Week 1 Update yesterday from developer Vlambeer, it’s Nuclear Throne:

If you have a Warp Zone Suggestion, please head over to Update #6 to comment!

If you have an Add-on Question, there’s a ton answered on Update #7 and in the FAQs!

Other than that, the best and quickest way to get your campaign questions answered is to engage the community in the Comments section. While we will eventually get to all of the Direct Messages, answers there will be answered in days, not minutes like Comments are. You should also check out the FAQ section, we keep adding answers there, yours may already be answered.

Thank you for your support!

Week 1 Recap
over 2 years ago – Tue, Jun 08, 2021 at 04:37:17 AM

Hello Friends!

It’s the end of week one of the campaign. We’re going to take a moment to wax poetic so forgive us. Your pledges have made this game possible. As an independent publisher, getting games to market is an incredible financial burden controlled by Big Board Game. Ya, it's totally a thing. Kickstarter allows independent publishers an opportunity to make their dreams a reality. You have blown past our dreams. Your pledge employs hundreds of people at the factories to print the game, the boxes, the figures, the merch and other trinkets. It employs hundreds of people in the fulfillment centers and shipping of the game. It pays the artists who have put their blood and sweat into designing the game. And you’ve ensured that we can continue to create and publish far into the future. That is no small thing.

We’re far from the end of this thing, so we’ll save the rest of the sentiment for later.

Let’s recap Week 1!

You crazy people funded our game in under 3 minutes and raced past the $1,000,000 mark in less than 90 minutes. At the 12 hours mark we reached 19,000 backers. At the end of 24 hours we had over 22,500 backers and raised over $2.8 million. You blew past so many Stretch Goals that we had to play catch up on announcing all of them. Here’s the list of what you’ve unlocked in less than one week:

10 Stretch Goals in 1 Week!

Then you got to work on the Social Goals, you’ve completed so many Social Challenges in one week that we’ve already had to think of more and harder ones for the future. Each completed Social Challenge has unlocked 1-5 Warp Zone cards. Cards from other games and franchises that are now included in the game!

10 Warp Zones Unlocked Through Social Challenges!

And every time we gained another thousand backers, we added an Alt Art card to the game. These are in addition to the cards that are already in the game, it just gives a second card by an amazing guest artist. These too you’ve blown past so fast that we can’t keep up! We’ve shown off a ton already, but we still have more to show to catch up!

We've unlocked so many more!

It has been one hell of a week and we’re just getting started.

Stay Tuned to the Updates for more spoilers, more about the new mechanics, and more about Merch!

We'd also love to hear what you're most looking forward to as the Kickstarter goes on! What topics can we help unravel in future updates?

Add-ons! Stretch Goal PINS! More Warp Zones and Alt Art!
over 2 years ago – Tue, Jun 08, 2021 at 03:06:53 AM

Hello Friends,

I wanted to take a moment today to talk about add-ons. Kickstarter recently launched a beta version of an add-on feature. This feature will one day be a great addition to this amazing platform and we look forward to using it in a future campaign!

If you’ve backed Binding of Isaac: Four Souls, Tapeworm, or any other number of games that launched on Kickstarter, you’re already familiar with the Backerkit add-on process, but here’s a quick refresher.

There are two ways you can handle add-ons while the Kickstarter is live.

  1. You can back a pledge level as low as $1 to gain access to Backerkit. Pledge and pay for just the tier cost and you’ll receive access to the pledge manager. Once the Backerkit pledge manager opens post-Kickstarter, you’ll be able to pick and choose which add-ons you want, add them to your cart, and pay for them at checkout.
  • When you select a tier, there is an option to add “bonus support.” Increase your bonus support by the amount of the add-ons you’d like to purchase. The list of prices for add-ons is near the bottom of the campaign page. Doing the add-ons this way will help push the Kickstarter needle further, and help get everyone closer to more stretch goals! The money will be collected at the end of the Kickstarter and will be available when the Backerkit launches. You’ll then select which add-ons you’d like in the pledge manager just like any online store. The “bonus support” will act like a credit in Backerkit up to the amount you added.

If you have a question about add-ons, this is the place to ask it!

It will help us corral certain questions in specific areas!

Warp Zone Suggestions/Questions on Update #6

Campaign News 

We hit another huge milestone today and unlocked PINS! It’s incredible how far we’ve come in just 5 days. Here’s a look at those pins!

Now that we’re solidly above $4MM we have our eyes firmly set on the final two stretch goals and a bonus Stretch Goal!

At $5M we’ll unlock blank cards. We were shocked at how often this was asked for, and we’re bringing it to you! Create your own card to add to the game with this Stretch Goal!

We're rapidly approaching another Milestone: 38,335 Backers. This is the number of backers of our original campaign, and we're poised to surpass that. Once we do, we're going to add even more temporary tattoos as a thank you!

At $6.66M we’ll unlock the FINAL Stretch Goal! This is a big one and adds 5 extra Tear Tokens, 5 extra Heart Tokens, and 20 extra cards. TWENTY CARDS! What are these cards you ask? We’ll all find out when we hit $6.66M.

With your continuing support, we can get there sooner than we ever thought possible.

Unlocked Cards

Alt Art cards continue to unlock for every 1,000 backers. Here’s a look at a few more you've unlocked:

 On the Social Challenges front, you all are well on your way to unlocking the next set of Warp Zones. We’ve seen ‘em, they’re epic, and we can’t wait to show you.We owe you a Warp Zone reveal from yesterday and here it is:
