Latest Updates from Our Project:

Charmed Enemies, More Warp Zones and New Social Goals
over 2 years ago – Tue, Jun 08, 2021 at 03:06:50 AM

Happy Sunday Friends,

The weekend is wrapping up, but we’re still going strong! I wanted to spend a little time today talking about Charmed Enemies. These devilishly cute enemies add a whole new dimension of play and force even the most hardcore backstabbers into helping others. You never know when the next charmed enemy will show up in the Monster Deck and they act like any other enemy and must be defeated just like any other enemy. Each charmed monster comes with its own unique bonus for defeating it, and each one helps another player. How will you choose who to help? How will helping someone hurt another? We also like this mechanic as a way of balancing the field when certain players are lagging behind.

Room Deck, New Social and Alt Card Unlocks!
over 2 years ago – Sat, Jun 05, 2021 at 03:45:08 AM

It’s the end of day four Dear Friends,

Over the next few days we’re going to be discussing specifics of certain aspects of the game. If you want to see what crazy things you’ve unlocked, scroll down to the campaign news section, this will be included daily after talking about an aspect of the game.

Room Deck

We wanted to take a moment to talk about one of the biggest updates to The Binding of Isaac Four Souls that is being added with Requiem. We’re talking about The Room Deck.

 This devious deck of cards is designed to bring a whole new interactive element to the game.

This 55 card bonus deck features 10 "curse" cards, 10 "blessing cards," 20 "neutral" modifier cards, 10 interactive "item" cards, and 5 dice rooms that shake things up. This deck is optional and we recommend playing at least a few games without The Room Deck to familiarize yourself with the rules and play before adding this advanced deck.

The rooms are blind drawn, so you won’t know the effect until you draw The Room Card from the Room Deck. On most cards you’ll have the option to use the card benefit if you’d like, but on others, the global effect will be instantaneous and ongoing. FI you killed a monster on your turn, at the end of your turn you can choose to discard that room card and reveal a new one or leave it in play.

Campaign News

After 96 frenetic hours of fun it’s clear that we have THE BEST BACKERS on Kickstarter. Since we revealed the Social Challenges, you have already completed most of the originally planned challenges:

Here’s the Newest Social Challenge Set, you now have to complete ALL challenges to unlock the Next Warp Zone!

You can participate over on Twitter and be the first to see the next set of Social Challenges by following @EdmundMcMillen and @TheMaestroTeam.

Is there a particular game you’d love to see as a Warp Zone? Let us know in the comments!

Speaking of unlocks. We’re still adding a new Alt Art Card for every One Thousand backers that join the Kickstarer. We’re up to 32 Cards now! Here’s a peak at a few more:

Please remember 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 again for your support, we’ll be back tomorrow with even more fun.

Day 2: Stretch Goals, BGG, Livestreams, Communication
over 2 years ago – Sat, Jun 05, 2021 at 01:53:12 AM

Our Friends,

You all are KILLING it! Here’s a look at the Stretch Goal Alt Cards that were unlocked today:

Stretch Goals

Backer Goals - Today we added 5,783 backers and unlocked 5 more Alternate Art Cards! For those of you asking, these are in addition to the cards that are included in the game already.

 Financial Goals - Y'all have busted through two more Stretch Goal unlocks today, soaring closer the the next Stretch Goal at $4MM. You've unlocked 5 Temporary Tattoos and the Samuele Gabbanini Coloring Page. Keep up the amazing work! There's more on how you can help keep the unlocks rolling below. 


We also wanted to talk about Board Game Geek again, with your help The Binding of Isaac: Four Souls has shot up to NUMBER 18 on The Hotness List! That is amazing, please help us out by clicking HERE and interacting with the page by clicking the Fan heart or leaving a rating.

You can also help get The Binding of Isaac: Four Souls Requiem onto that Hotness list by clicking HERE and interacting with the page by clicking the Fan heart, adding pictures, or posting in the forum.


Edmund continues his livestreams, one is live in less than an hour at 22:00 PST HERE. He’ll be doing these livestreams throughout the Kickstarter, so make sure to check his Twitter for announcements.

We have received over 1000 DMs, we're slowly getting to all of those. The best way to get quick answers and to benefit all backers is to post in the Comments section as opposed to DM. This is also where you should post your love for Edmund and his games to ensure that he sees it!

More Social Goals and Warp Zones
over 2 years ago – Sat, Jun 05, 2021 at 01:53:06 AM

Well look at you friends,

You’re crushing Social Goals left and right! Forgive us while we scramble to think of even more. We only made 10 thinking to ourselves, "There’s no way they’ll be able to accomplish all of these. It’ll take 2-3 days per set for sure!" Well, you continue to blow us away with your passion. You blew through EIGHT Stretch goals. Then you said “Hold my beer (or soda),” and knocked out TWO Social Goal sets. 

We’re onto the third set of goals - THE MAUSOLEUM! You can participate on Twitter by tagging @EdmundMcMillen and @TheMaestroTeam.

  Here’s a recap of what you’ve unlocked:

 You unlocked Ash, Ball of Tumors, Chunk of Amber, and Brea in Distress last time. Read about it in UPDATE #3.

The second set of Warp Zone cards are from the Spelunky Universe from Derek Yu.

Guy Spelunky and his Eternal item Spelunking Pack are all about making money, killing monsters, and messing with the shop!

The Shop Keeper is a beefy enemy who is hard to hit. He lets you steal from the shop, but be careful. If he catches you… you’re pretty much doomed.

Finally, the Golden Idol. This item is pulled from the Monster Deck and becomes eternal to the player who revealed it. While it’s a financial windfall, it also makes the player who holds it vulnerable to attack from every other player. When the player holding the Golden Idol dies, it passes to the player who did the defeating. AND IT NEVER GOES AWAY.

Day two still has just under 10 hours to go. Let's get to the next Stretch goal, and GET THROUGH THE MAUSOLEUM! We can’t wait to show off the next Warp Zone!

You can help us out right now by talking about Requiem on social media, on, in your local retailers, shouting it from the rooftops, screaming to your neighbor about it through the wall.

Thank you for your support!

We Surpassed the First Kickstarter! And Social Goals
over 2 years ago – Sat, Jun 05, 2021 at 01:53:01 AM

Umm... we just surpassed the BOI: Four Souls Kickstarter… in 17 hours and unlocked all-new Isaac tattoos which we are busy designing right now. :)

We’re all delirious from lack of sleep. We had to call some people to confirm we weren’t dreaming. We’ve been saying it all day, but thank you. It’s incredible to behold the enthusiasm and the community support.

Speaking of community support, Edmund announced the first social goals on Twitter today and you’ve already blown through the first group:

We’re onto the second set of goals, THE MINES! You can participate on Twitter by tagging @edmundmcmillen and @themaestroteam 

By defeating Downpour, you’ve unlocked your first set of Warp Zones. 

You’ll know Ash from The End is Nigh! His Eternal Item has some fun new features. Leveling abilities: can level up, level down, or both. To level up means to put a level counter on the object that is leveling up. I bet those tears y’all unlocked would work great. To level down means to remove a level counter from the object if you’re able to.

You’ll also have noticed the Chunk of Amber from Gish! This lil fella from the Loot Deck can get you anywhere from 2-12 coins!

And finally we have Brea in Distress also from Gish! That’s 2 from End is Nigh! & 2 from Gish! for those keeping score. This is an Event Card in the Monster Deck. When spawned, it makes you roll in an attempt to save her. If she lives, she becomes a trinket that raises your HP!

Hustle through THE MINES! We want to see what Edmund has in store for the next Warp Zone!

Edmund will be live streaming here at 10pm tonight PST to answer any Kickstarter questions and celebrate an incredible first day! Please join us.
