(That only implies estimated release, it's still better to trust ed that it might be delayed. Goat Hoof was gulped (it was confirmed that gulped items appear in the item hud), there's no reason to have a +0.15 speed up as a passive. The animation is not old as long as it's in the current version of the game.)

Contents

The following information/confirmations of The Binding of Isaac: Repentance, an upcoming DLC set to be released by the end of 2020, has been collected:

2018

August

August 30th (Reveal)

A "title reveal" for a new expansion was released by Nicalis on Youtube.

The trailer revealed the title of the expansion and its logo - strikingly similar to that of The Binding of Isaac: Antibirth, a fan-made expansion of the game that received critical acclaim from the community but despite popular demand seemed to have little chance of being brought to the official game. Additionally, it was announced on Twitter that Repentance would be available for play at the PAX West 2018 Convention.

August 31st

The demo version of Repentance playable at PAX confirmed suspicions that the expansion would indeed be a port of Antibirth. Original content from the mod that led to this conclusion as well as brand new content in Repentance that was discovered in the demo included:

September

September 1st

Edmund McMillen officially discloses details of the Repentance expansion pack on Twitter.

  • The Repentance DLC is officially announced to include the Antibirth mod alongside a ton of other new content - Edmund affirms it is "the FINAL (for real this time) DLC for Isaac".
  • Edmund will be working with the full team of Antibirth developers (Public Entertainment Networked Interactive Software - also known as P.E.N.I.S), _Kilburn, LeatherIceCream, and NotYourSagittarius, on the Repentance DLC, which will also be published by Nicalis.
  • Repentance, as a substantial addition to the game, will cost money.
  • Repentance has no set release date yet - however, remaining Booster Packs are being worked on and expected to release within the next 2 months on the console.
  • Repentance will feature a new cutscene(s) & lore in the Isaac story.
  • Repentance's soundtrack will be fully composed by original Isaac: Rebirth music composer Ridiculon (in name of cohesiveness) and not Antibirth soundtrack composer Mudeth, contrary to the expectation of a full port of the mod's content - Mudeth adds that he will finish working on his soundtrack nevertheless, but that it will have to be modded in instead.

Tyrone Rodriguez posted a tweet with "#IsaacRepentanceDev" hashtag of a gif showing off a new item, as well as new visual shaders in the Burning Basement.

September 3rd

This gif shows Apollyon in Downpour with Curse of Darkness active. Some noticeable changes include:

  • A new version of the item tracker, with smaller item icons meaning more items will be shown in the tracker compared to the original Afterbirth version.
  • Possibility for the item tracker to be enabled separately from the game timer.

September 4th

Video footage of _Kilburn playing the Repentance demo on the last day of PAX West was recorded and uploaded to YouTube by a member of the community. However, the original video was eventually taken down, but it was then re-uploaded by another member of the community.

  • A mechanic of the Dross floor is demonstrated - there are rooms with rushing water that will actively affect Isaac's movement
  • New item revealed:
    • Plum Flute
  • New enemies:
    • Previously described green variant of an Attack Fly that moves in a single file along with other green flies.
    • Variant of Mulligan that chases the player and periodically spits out poison gas. And it also fires an Ipecac shot upon death.
    • A spherical Dip variant in Dross that does short rolls randomly around the room, spawned by Dross Squirts upon death and Clog.
    • A humanoid enemy in Dross that floats and chases Isaac. Surrounded by Attack Flies.
    • Video footage of Clog's attacks and tactics in his battle.

This gif appears to show Eve in Dross, attacking some of the new enemies.

  • The gameplay also reveals the Antibirth version of the Found HUD
  • A new rune that can be seen dropping next to Eve at the end of the video.
  • Eve appears to have a new hair sprite for her Whore of Babylon state.

  • More synergies to several items like Mom's Knife Mom's Knife will be added to the game.
  • Mama Gurdy's appearance will be renewed, other visual updates regarding bosses are unknown.
    • Gameplay-wise, already existing bosses will get no new attack patterns.
  • The puzzle of the Knife Pieces will be changed.
  • Edmund's latest games such as Bum-bo and The End Is Nigh will be represented in Repentance.
  • Repentance will add a unique savefile image when completing all three files.
  • Regarding the question of a possible rework of the Keeper, Edmund replied with "you'll see".
  • Blog posts regarding the DLC will be published before the expansion will be released, possibly revealing more content.

May

May 11th

Tyrone Rodriguez posted a new gif showcasing the significant changes made to Telekinesis Telekinesis, alongside many other minor changes.

The changes that are shown in the gif include:

  • Telekinesis’s effect now having a visual tell for the radius in which it can pick up shots, though the time for which it can collect shots has been shortened. When collected, enemy projectiles begin to flash white until they are thrown back by the player. The projectiles that were thrown back also get to keep their visual and mechanical properties, such as bones thrown by Bonys‘ projectiles retaining their bone appearance or Gurgles’ projectiles remaining explosive.
  • Gurgle projectiles blinking more profusely, much as the enemy blood projectiles do. They also retain a noticeable hunch previously seen from the last Rep demo that is based on their Wrath of the Lamb incarnation.
  • Gurgles also turning into green gibs and bones upon death, either for consistency with Gurgle’s generally green coloration or because of a returning Flash feature where poisoned enemies would drop green gibs on death.
  • The gibs that break apart from Bony’s bone projectiles now using their previously underutilized animation where they would gradually shrink upon hitting the ground.


May 17th

Edmund states on Twitter that while the planned release was at the end of summer it will likely be pushed back due to the ongoing Covid-19 pandemic.

He also talks about stuff that needs to be worked on- which include some bosses, items, cut scenes, and "bonus things".

Additionally, he posted a picture of what seems to be the final cover art.

June

June 23rd

Kilburn responded to a fan on Twitter asking for exactly 2.75 seconds of each new song on the soundtrack.

There seems to be a total of 10 new themes. These are in the following order:

  • Downpour
  • Mines
  • Mausoleum (speculated)
  • Corpse (speculated)
  • Dross
  • Ashpit
  • Alternate boss theme for Antibirth floors
  • New final boss theme (speculated)
  • 2 unknown themes, possibly intended for Planetariums or cutscenes.

Some songs may be missing or have been excluded from the video to prevent spoilers or because they haven't been finished yet.

June 24th

Edmund posted a tweet stating that most of the new cutscenes are finished.

June 28th

Edmund posted a tweet stating that Repentance development is getting back to the normal speed. Cutscenes and music are nearly done, while some enemies and items from Antibirth still await porting. The goal was the end of the summer and he assumes the delay is going to be 1-2 months at this point.

July

July 21st

Edmund posted a tweet stating that the development of Repentance is near its end with two remaining music tracks of its wide library. He also says that some end game stuff will be finalized this week, and after this, they will finally move onto the game's final unlocks and some remaining bosses and enemies.

Later that day, a user asked in his tweet if the DLC could be released before September/October, on which Edmund replied, negating this information.

July 23rd

Edmund hosted another Twitter AMA where he disclosed a few new details about the upcoming expansion.

  • Pills will be changed in some way, shape, or form.
  • There will be a new tear modifier in the update similar to Tech X or Brimstone.
  • The expansion is still expected to launch in 2020.

August

August 27th

Edmund hosted a Twitter AMA where he stated that blog posts and a Steam page are expected in mid-September.

In his Twitter AMA, he stated that the price of Repentance will be between $12 to $15.

August 31st

Edmund responded to a quick Twitter AMA regarding the possibility of another series of Booster Packs in Repentance, stating that if they were to be made they wouldn't be announced and be a surprise.

On his latest Twitter AMA, Edmund replied to a tweet that The Witness will not have her special giant room design and will be in a smaller room. However, The Witness will be changed to fit that new design.

September

September 4th

Edmund posted two gifs on Twitter, one featuring a thin creature while the other depicts a similar creature that is bloated, both displayed in the form of gifs of front-walking animations. The former has an armless, flesh-tone body covered in blisters and holes, while the latter has a rotund, grayish body with a large stitch in the center. Both heads are bisected into a fleshy half and a grey half, stitched together in the center, and the eye that’s opened on their half of the head is respective towards their body type. Later on, Edmund would confirm that these are two separate “twins” with a complex relationship. It is currently unknown if these entities are bosses or complex enemies.

September 9th

Tyrone posted an image of what appears to be the new title screen for Repentance. Further, when asked if Repentance would be ported to the Switch, Tyrone responded "Yes, but it'll take some work. Lots of optimization [is needed]."

Kilburn posted a gif on Twitter.

Details from the gif include:


September 11th

Tyrone posted a blurry pic on Twitter. It appears to be the costume for Metal Plate Metal Plate possibly designed as a teaser.

Repentance Blurry Teaser.jpg

September 13th

During a Twitter AMA, Edmund was asked an approximate release date for Repentance. He responded, "I mean the goal was end of summer and then the world ended [COVID-19] and production slowed... the goal is still this year, but honestly when it’s done it’s done." When another user asked if Edmund is 100% sure Repentance will be released this year, Edmund did not directly answer the question. Another user asked how much of Repentance is done on a percent scale. Edmund responded, that Repentance is 85% done.

Edmund noted that Repentance is "very close to [being] an isaac 2." and, "a major bookend to the "series"." Edmund also mentioned that a lot of the ideas used in Repentance "were ones locked away for isaac 2 especially cutscene wise." A user noted, "If repentance is substantial enough in content, whatever sequel there will be for Isaac will then be a very long way away and be completely different because more of the same could just be another update to the original." Edmund agreed.

Edmund was asked if an additional horseman that was planned to be in the Antibirth mod will make it into Repentance. Edmund responded, "I’m not aware of any horsemen planned."

September 14th

Tyrone posted a tweet on Twitter. He posts some of the letters to the names of one or possibly two bosses.

September 22nd

Tyrone posted a teaser gif on Twitter.

Details from the gif include:

  • ??? fighting two Hardies from Antibirth with improved animations.
  • The Myosotis trinket from Antibirth.
  •  ??? having a unique costume for Speed Ball Speed Ball that keeps his X eyes (likely other items have new costumes as well).
  • Bombs having a lit fuse animation from Antibirth.
  • Scatter Bombs Scatter Bombs having a unique bomb costume and the small bombs that spawn after the main Scatter bomb exploding almost immediately.
  • There's Options There's Options appearing to have a new sprite or a new item with a similar design.
  • There are two shadows appearing in the center of the room right after killing all enemies, indicating two rewards for clearing the room. This may suggest that either ??? or some of his items were reworked to give more rewards, the Myosotis trinket doesn't have its effect from Antibirth, or this is the effect of the There's Option-like item.

Details from the gif include:

At the end of the day, Tyrone also put a link to the official Steam page for the game, which reveals more images with more content. It also states that there will be 130+ items, A full alternate path with brand new chapters and a new final boss and ending, 100+ enemies, 25+ bosses, 2 new characters (Bethany and Jacob & Esau), 5 new challenges, 100+ achievements, and 5,000+ new room designs. The page also says that the dlc will come out on December 31st, 2020, but it's likely just a placeholder. Unfortunately, according to Edmund's response to a Tweet, the DLC won't be released for the Mac.

    • The Book of Virtues from Antibirth now appearing to be a passive item, while also showing as an opened book under Bob's Rotten Head Bob's Rotten Head.

    • Oculus Rift has a new effect when a rift appears.
    • Dirty Mind will work with black poops.

October

October 9th

Tyrone posted another blog post on Steam in which he interviewed the Ridiculon, the musical duo responsible for The Binding of Isaac soundtrack, and showed another screenshot of the DLC. In the interview, Jon also mentioned that there are nearly 45 minutes of new music and that a new song named "River of Despare" will be revealed next week.

Isaac blog 2.png

  • Items from Antibirth:
  • Changes:
    • Eternal D6's recharge time was lowered from 3 to 2 rooms. Or this may actually be D Infinity D Infinity that transformed into it, which always has 2 charges.
    • Bob's Curse Bob's Curse has a slightly tweaked shape.
    • Previously shown Scatter Bombs Scatter Bombs new design is compatible with other bombs modifiers, such as Bob's Curse.
    • Spiked rocks from the Antibirth mod have returned with a redesigned sprite, although this could simply be a design variant.
    • The tar in Dank Depths is leaking from the top of the walls, instead of leaking from wall cracks.
    • A closer look at the new Dank Depths background, with pillars near the corners of the room.
    • The previously seen dank version of Hopper appears to leave a puddle of black creep and a chaotic splash of tears similar to Monstro, though with much fewer tears.

October 15th

Tyrone posted a new blog post. It is following his last blog post in which he interviewed the Ridiculon duo, creators of the Isaac soundtrack. On this new blog post, he revealed a new GIF, a teaser of a soundtrack called River Of Despare and goes into details about how this theme has been created by Ridiculon and Edmund itself.

  • Changes:
    • Azazel's appearance was redesigned, his hair and horns are now fully colored and his opened mouth now better resembles the new Brimstone costume.
    • A new synergy between Lachryphagy Lachryphagy and Brimstone Brimstone - character rapidly fires a stream of small fully-red shots alongside the blood barrage, which quickly combine into one big tear if the character doesn't move, and also burst into 8 blood shots instead of laser beams.
    • A new item which looks like an opened can, probably gives a health up. Might also be a reskin of Dinner Dinner.
    • A new trinket which looks like a key. Its effect is unknown.

On the blog, there is also a link which redirects to a new official SoundCloud account for The Binding of Isaac. That link features a brand new theme made by Ridiculon, called River Of Despare.

In the blog, Matthias said, "The River of Despare, it's a distance cousin of Sodden Hollow. Expect dank, liquidy and a slow drum groove. What you're going to hear is more of an ambient feeling of sudden hallow and what was spawned a lot of the Isaac soundtrack."

This soundtrack was previously featured in recorded footages of the Binding of Isaac: Repentance PAX gameplays during the Downpour stage, this time with slight alterations including a new intro track and the sound of water slushing during most of the track.

October 17th

NotYourSagittarius posted a tweet on Twitter.

Though mostly showcasing a meme, this video shows that Hush's bullets blink much more vibrantly.

October 20th

Edmund McMillen revealed more information through a Q&A on Twitter:

  • A unique theme for the Utero floor will be added.
  • Gurdy's laughing animation that could be seen in the Flash game will reappear.
  • Kilburn will look into re-adding the tear stain trails that from the original game/Pre-release Rebirth gifs, though they may be post-release.
  • Greed and Greedier mode won't receive many changes.
  • Edmund reconfirmed that some elements from Antibirth will be renamed, changed or removed due to overlapping effects.
  • Confirmed Antibirth enemies:

Edmund also gave his reason why Mudeth's soundtrack won't be featured in Repentance.

October 22nd

Tyrone Rodriguez posted a new blog post, in which he interviewed the members of the Repentance development team: _Kilburn (lead designer), LeatherIceCreme (designer), and NotYourSagittarius (artist). Tyrone also shared concept artwork for some new bosses and enemies and pre-production dev screenshots (in form of gifs).

Isaac blog penisinterview1.gif Isaac blog penisinterview2.gif Isaac blog penisinterview3.gif

Most notable features from the gifs include:

  • Returning boss from Antibirth: The Pile, with a redesign and new visuals.
  • Items from Antibirth:
  • An unknown trinket that looks like a red button.
  • Robo-Baby Robo-Baby now being able to fire diagonal. Might be an effect of King Baby King Baby.
  • The new Dross enemy that resembles a gasper from Tein explodes when it collides with an obstacle, although no source of damage can be seen. This may be caused by the new trinket or a special characteristic of this enemy.

October 28th

Edmund McMillen shared more information during a Q&A session on Twitter:

  • Besides the addition of True Coop, Repentance will introduce more coop babies as well.
  • The song "Jesus Loves Me" from the original game will return.
  • Super secret rooms and the item RNG will be tweaked in some form. Further details were not given.

October 29th

Tyrone Rodriguez posted a new blog post, in which he interviewed the members of the Repentance development team again.

New details on the upcoming DLC include:

  • One of the new floors has a special visual effect that isn't shaders. It blends a couple of scrolling layers with the overhead shadow that's visible on most floors to achieve a "rather nice atmospheric effect".

November

November 4th

Tyrone Rodriguez posted a short blog post, in which he provides a link to another track preview from Ridiculon. This track is called Fissure, and it is used in the Mines.

The post does not include any new information, but it does provide some insight into the track and how it was created.

November 14th

Tyrone Rodriguez posted a new blog post, in which he interviewed Edmund McMillen. The interview also included gifs with new details, with most of them being brought back from the Flash game:

Isaac Blog Fistula.gif Isaac Blog Holy Water.gif

Old details from Flash:

  • Fistula's color palette was changed to be darker brown, and the shape of some of its small fragments were also tweaked.
  • Spoon Bender Spoon Bender now having an animated flame on top of Isaac's head, and Isaac's eyes now always being closed with this item. A purple lighting effect also surrounds Isaac.
  • Holy Water Holy Water now having a transparent container. The water also acts like actual water, with the animation of waves inside the glass.
  • Magic 8 Ball Magic 8 Ball appearing to be darker.
  • Eye now glows red and squints right before firing his laser.
  • Second gif shows Isaac having 1.54 shot speed, even though his items should only increase it by 0.49 (for 1.49 shot speed total). This may suggest that either one of his items was buffed to give 0.05 more shotspeed, or that Shot Speed Up pill will be added from the Flash game and the Antibirth mod.

New changes:

  • Lil Gurdy Lil Gurdy bounces off enemies and rocks, and not just walls.
  • Dry Baby Dry Baby now has a rounder head and a subtle moving animation, similar to many other familiars.
  • Placebo Placebo is shown with a 1 room charge instead of the usual 4 room charge.
    • This may hint at Placebo having a fluctuating charge time depending on currently held pill.
  • Lil Delirium Lil Delirium and its familiars having circular eyes instead of dots, along with having a pallet much closer to Delirium’s main form.
    • Lil Delirium's icon also seems to have been changed, with a more melted appearance.
  • Lasers' impact effect bounces against the walls, instead of spreading in all directions.

November 19th

In a brief AMA on Twitter, a user asked Edmund if Repentance is delayed to 2021. Edmund replied "Probably, but it’s close". It was not clear if he meant Repentance was close to completion, or if 2021 is close anyway. Edmund also stated that he will do a pre-release stream of Repentance.

November 21st

Tyrone Rodriguez posted a new blog post, in which he continued interviewing Edmund McMillen.

Information from the interview:

  • When asked if he was happy with Repentance, Edmund started talking about little details that were in Flash and how they brought them back in the game. Including a few hints on what some of them are:
    • "There’s a ____ _____ ____ that’s in ___ ____ and it’s ______ ____ _. You have a _____ of ____ and it’s _____ across_ and it’s _____ and _________ and doesn’t ____, but it’s one of those _____ things _____ that will _____. It’s one of those little things. That happened a lot in the Flash version. I think with Repentance, superfans will really feel that the world is even more alive. And little things that creep up on people, or really rare stuff that creates this illusion that the game goes infinite."
      • If each underscore counts as one letter, there's a few excess singular letters that can't be decoded into anything meaningful.
  • Edmund stated that the game ____ __ _____ changes the Repentance experience.
  • When Tyrone reminded Edmund about porting the game on different platforms, he replied with the following:
    • "The thing is, I want people to know that ______ _____. We don’t not want to ____ ___, but when the time comes soon, when we do a release trailer we’re going to ____ ____."

The interview also included one gif of the upcoming DLC.

Isaac blog knifesknifesknifes.gif

Details from the gif include:

  • Luna, a returning Planetarium item from Antibirth, with a different character's appearance or maybe even a new mechanic.
  • Unknown trinket that looks like a file.
  • Goat Hoof Goat Hoof got a minor redesign.
  • Betrayal Betrayal no longer playing animation that covers the entire screen; instead, it shows a knife above enemies' heads.
