The Binding of Isaac: Rebirth is a whole remake of The Binding of Isaac releasing on November 24, 2014. This article details the pre-release content of it.

December 1, 2012 (Update #1)

Edmund McMillen made a public announcement, revealing the game's details:

"After receiving 80+ questions via formspring and many via email, i have amassed what i believe to be a definitive check list that should clear up most-all confusion on what the binding of isaac remake (Binding of isaac: Rebirth) is/will be."

  • Rebirth is a totally remade game based on the flash version of the binding of isaac + wrath of the lamb.
  • The game is being produced and developed by Nicalis, the guys who did all the cave story remakes and the VVVVVV port.
  • Nicalis is working on the port for Ps3/Vita and PC (steam) and is also currently talking to MS and Nintendo about releasing on their platforms. we are also looking into an iOS version if its not garbage.
  • The remake will feature all the content featured in BOI+Wrath but will also feature another Wrath sized expansion over the top that will feature a new final chapter, ending, 2 new playable characters and tons more items, rooms, enemies, bosses and the like. the goal will be to make replaying the whole game not only worth it but also make i so it feels very fresh and new.
  • The remake will feature content that was removed from the flash version of the game due to limitations (secret stuff!)
  • The remake will feature LOCAL 2 player co-op… no online play because that will just extend the release by another forever.
  • The game will go into full time development the 1st of the year and is set to be finished by the end of the year (but we know how this stuff goes)
  • The game will feature new music by Danny B as well as some spicy remixes of old tunes.
  • I will be lead designer on the project, making sure things are as perfect as we can make them and as true to the original as possible, i will also be designing all the new content and features.
  • The game will be getting a full 16bit make over, im doing this because i think the art is tired and im sick of looking at it. i think a fresh coat of paint is needed and i think its kinda appropriate/funny to do a damake for the remake.
  • We will try to do a loyalty pre-order discount to anyone who owns the game on pc.
  • The ability to save and return to a play session. this is something we wanted to do in the flash version but couldn’t due to limitations, this will def. be a feature in the remake.
  • Co-op: local co-op will be added, this may include local host or split-screen.
  • Yes, like i mentioned in the post, the remake will feature A LOT of new content that players will see and interact with from the start of the game to the end (the new final final end). we are going to pack this thing full of all the stuff we couldnt do as well as a ton of secrets that should stay buried for a while… the game will also feature 2 new characters, and with each character comes a new set of items each one unlocks by beating the now 5 final bosses.

tidbits:

  • the remake will run perfect/fast finally!
  • we went with nicalis because they were the only dev team im close to and that i trust with my IP.
  • the remake will be fully retuned, balanced and improved.

"the biggest thing to keep in mind here is that development is just starting with the remake, nothing is totally set in stone and a lot will change over time. Im currently in full time development of Mew-Genics with tommy and we have a few other little tricks in store for you next year so my goal with Rebirth is to simply make sure the remake is top quality and then detail out the expansion and updates once development is much farther along… this remake wont slow down any games im currently working (and thats reason why someone else is doing it!).

more updates will be posted as i get them :)

hope that clears things up.

-Edmund"

January 8, 2013 (Update #4)

The people from Twinfinite asked Edmund questions that they gathered from a reddit posts. (check it out here)

Rebirth details
  • Nicalis will focus on remaking the entire game (original + Wrath of The Lamb) with some tweaks, and then Edmund will step in to add the new content.
  • The art style will remain 16bit and the old art will not be included. Ed says that the style is getting there but needs some work, and that he will approve each piece of art.
  • Isaac's design especially is a WIP. His face will be bigger than it is in the original game because pixel art limits the amount of detail they can add with items, but how much bigger is still up in the air.
  • Arcades will be retooled so they aren't such a time sink, although he was unclear on how this would be done. He did say that the probability of machines blowing up will be higher than it currently is.
  • In general there will be a greater incentive to spend less time on floors. Some new items will somehow be sensitive to time, which was impossible in flash. Ed's goal is that the average run time in the remake will be a little shorter than in the current game.
  • Choosing between going to Sheol or the Cathedral will be more meaningful. Ed admits that in the flash version there's not much point in going to Sheol if you've unlocked the Cathedral. He hints that there will be some extra floor equivalent to the Chest after Sheol and that the choice between them will be more interesting.
  • There will be plenty of new challenge runs, but no custom run option ("definitely will not happen"). Ed says he wants the challenges to actually have some reward (an unlock) and that custom runs (a la the cheat engine) are essentially about hacking the game to start with items. He feels that if this was included in vanilla Isaac it would "break the game".
  • There will be some other feature that "touches" on the concept of custom challenge runs, but is "much cooler". Ed declined to elaborate, but said that it's one of the ideas he wanted to implement in the flash game, but couldn't due to technical problems. "People who want custom runs will be very happy with this feature, but in a lot of ways it can be a challenge."
  • There will be no wiki-like feature, telling you what items do. Ed mentions that he doesn't like the wiki because it "kills the magic" of figuring everything out for yourself.
  • There will be a new ending but Ed hasn't figured it out quite yet.
  • In a response to the wiki breaking everything down, Ed wants to add secrets that will be very hard to find and will stay buried for a while.
  • The stats screen is up in the air. Ed says he hasn't thought about it, but in general he wants it to stay vague.
  • There will be a Skatole-like item for spiders.
  • The remake will run "perfect". Little to no drops in the frame rate are a high priority. Fun fact, Ed actually refused to release Isaac because it had such a terrible frame rate. It was only until Tommy (the other half of team meat) took a look at the build that it got up to its current state, which Ed is still embarrassed by.
  • Lemon Mishap will get a buff. The creep will stay on the screen longer and it will recharge a bit faster. Overall, Ed says that there still will be shitty items and powerful items, but some of the more worthless ones will be made more useful.
  • Ed says that he "overdid it" with flying items in Wrath of The Lamb. Flying items will not get cut, but chances are that there will be no new flying items in the remake.
Trivia
  • Florian programmed much of Isaac in German. Ed will have Florian on to translate his code for the remake.
  • Soul hearts going off the screen was a bug. You were supposed to only be allowed the visible number of hearts, but Ed liked the mystery of wondering how many you have left so they never fixed it. Soul hearts being able to extend off the screen will be in the remake.
  • Ed dropped out of community college after some weird guy got the same grade as him in a 3D animation course.
  • Edmund admits that he never really had a clear vision of the story (what actually is going on in Isaac) and that it's developed over time.

Rebirth Gurdy etc Sprites

February 11, 2013 (Update #8)

Edmund talked about a few possible ideas with the Let's Player LethalFrag. check it out here

  • Ed has written up an idea for a possible playable character for Rebirth that fans of Loki will like.
  • The was an concept for a playable character called Mystery Man, a character with a question mark for a face that starts out with two random items. Every time you would beat moms heart (with any character) you would get a token, which in turn would allow you to play with the Mystery Man. Killing the final bosses (Mom's heart, Satan etc) unlocks new special items for him.
    • To quote: "This idea will definetely make it in. This will give an extra challenge to the hardcores".
  • "Show off your Isaac" will definitely be included.
  • As for Co-Op, Ed stressed the importance of "There is only one Isaac!"; something we should keep in mind.
  • More items for the shops. More items with modifiers and items like Habit and Mom's Purse. There was for example an item that raises the damage of blue flies. Or items that increase the power of familiars. Stores items can aid in more specific combinations.
  • Different item start loadouts for all characters
Trivia
  • Even Edmund does not know how the complete game works anymore, part to forgetting and part to bugs creating effects not intended.
  • Being able to slip past spikes was not planned
Some revealed details from Formspring
  • Some item descriptions will get a rework so they are better understandable.
  • Ed considers so kind of option for 100% players that could enable so called "challenge runs"
  • A quick-save function
  • +80 new items are planned, 61 are already on paper
  • 20 Cent items for shops!
  • Artists might be able to use their own skins for gameobjects
  • Rebirth will have a bit of an overarching theme
  • "My goal is to add another pages of challenge runs to rebirth"
  • Old content will get polished as well
  • DannyB's soundtrack might be unlockable in rebirth (high possibility)

February 21, 2013 (Update #9)

Some more details are revealed on Formspring:

  • A lot of changes to the effect of "Everything is Terrible"
  • There will be 2 characters in rebirth (technically one of them is 2 himself so maybe its 3 characters?). 2 of them have biblical names but thats as far as it goes.

  • More special rooms!
  • Some graphical updates to make stacked items look better
  • Hearts will be capped at 12 (assuming normal hearts were meant)
  • There's the possibility for an angelic counter part of Krampus lurking in Angel Rooms
  • Lemon Mishap gets a buff
  • Edmund might "do a bestiary like spelunky did", but he will continue refuse to add detailed item descriptions
  • The item Max's Head's name will be changed to Chricket's Head (one of edmund cats). The Luch item's graphic could also change accordingly.

April 12, 2013 (Update #18)

A new image was uploaded to tease a new boss (The Haunt) in a "Who's That Pokemon" parody sense. The early version for the new enemy (Lil' Haunt) is also there.

"Who's that isaac boss!?" / "*Rebirth tease*" / "His name is "The Haunt" and thats all the teasing of him you will get!"

April 15, 2013 (Update #19)

Edmund on Formspring confirmed that there will be a new key consumable that gives multiple keys.

April 17, 2013 (Update #20)

Edmund revealed a huge juicy amount of details during his interview with Northernlion.

  • Progress Report: All of the pre-Rebirth content art has been completed, and now Nicalis is working on randomizing rooms and the new content exclusive to Rebirth.
  • Ed says that he wants everyone who has played the flash version to have a reason to come back and pick up Rebirth. Rebirth will take advantage of its new engine, which means new content that was never before possible due to flash's technical limitations. Ed specifically hints at "bullet hell" and maybe even different sized rooms).
  • Again, Rebirth will run much more smoothly than flash Isaac, so say goodbye to that chugging frame rate!
  • It's been confirmed before, but there will be some sort of Chest analogue after beating Sheol. Ultimately Ed wants to make these two path parallel in terms of content.
  • The Mystery Man: Ed has hinted at this character before, but this time we get a more explicit explanation how he works. The Mystery Man starts with random stats and a few random items, and then it's your job to go from there. You might get awesome stats or you might get terrible ones, it all depends on what you roll at the start of the run. The catch is that you have to pay some sort of token to play as the Mystery Man. You receive those tokens from beating mom's heart, so if you try and fail as Mystery Man you may need to go back to other characters to earn more tokens. Ed says there will be some balancing mechanic preventing you from rolling a super-powerful (or super under-powered) character right from the start.
  • Rebalancing Soul Hearts: Soul hearts will not be able to go off the screen. Ed says "what you see is what you get." That means 12 heart containers max, including soul hearts! Ed points out that this will make the game harder for experienced players who know how to exploit soul hearts, not newbies who are still learning the ropes.
  • Rebalancing Items and Trinkets: Some of the shittier items will get a buff. Others will be turned into trinkets. For example, wiggle worm is now a trinket, along with a host of new trinkets that will affect how your tears move.
  • New familiars with differentiated abilities (meaning that they won't just be turrets)! In Rebirth you will be able to have more than 6 maximum familiars at the same time. Yay, new engine!
  • There will be plenty of bug fixes as well as more clarity on what items do. A lot of the bugs associated with Isaac are due to the limitations of flash and Action Script 2. With the new engine you can expect items to behave as intended. Ed also wants to make the game a bit more clear on certain things for players. By that he doesn't mean flat out telling you what items do, but he does want the short item descriptions and displayed stats to actually be helpful and reflect what is actually going on.
  • But there will more mystery as well. Ed wants the wiki to have to take a bit of time to catch up with all of the hidden content. The community will have to work together to find all of the extended secret areas (sort of similar to the secret areas in Spelunky).
  • Rewards for completing bosses/floors/runs under certain times to incentivize speed runs. By reward Ed usually means a new item unlock.
  • Rewards for ingenuity: What happens when I use the shovel in Sheol? Nothing in the current game, but Ed wants to reward players who try! Maybe if you try using items in interesting places you'll open up new content!
  • Co-op Multiplayer: Ed has already hinted at some of this before, but it's worth re-mentioning. Multiplayer will be local only and Co-op based. A second player will be able to drop in and the game will scale accordingly. Both players will be on the same screen, however Ed affirms that there is "only one isaac". That means that Player 2 may be controlling a totally different character.
  • There are also plans to allow players to compete in fair races in Rebirth. Although there is no online multiplayer, you will be able to get a code for a particular isaac run. You can send that code to a friend, and when entered in into the game it will generate the same rooms, enemies, items, and floor maps for both players. This will make it possible for players to share runs and thus make it a more fair competition if you and your buddy want to race to Sheol.
  • Ed is not a fan of Isaac on touch screens, so I hope you're not holding out for Isaac for iPad.
  • New cutscenes and voiceovers? Only time will tell. Ed say he will not just remake the old cutscenes with 16 bit graphics. Either he will reuse the old ones and add to them, or remake them all. Ed also wants to get more of Matthias Bossi's narration in the game (he voices the intro cutscene). Since Bossi is doing the music for Mewgenics, Ed's other game in development, it's certainly a possibility.
  • A hint at one of the 100+ new items! This was already covered by reddit user elucidater.

A new item is also revealed, called Tiny Planet. It appears as a moon-shaped object which gets embedded in your head.

Effect: It maximizes your range stat but makes all tears revolve around Isaac's body, much like an attack fly. The idea is that there will be a ton of tears revolving around you, much like the Duke of Flies' flies. Each tear will rotate around you roughly twice and the idea is that it changes the whole dynamic of play.

May 8, 2013 (Update #21)

Edmund from Formspring revealed new details about the shop - "you can expect there to be more stuff in shops and more stuff to do with shops... but same number of shops per level"

October 26, 2013 (Update #27)

Northerlion and Bisnap interviewed Edmund on a Twitch.tv stream [1], asking him various questions suggested by reddit users.

  • Edmund wants to support modders, although he has no idea how.
  • The Polaroid Trinket will be no longer be needed to go to The Chest, and will probably be removed/changed.
  • Edmund has designed 120 new items, although they are not actually in the game yet.
  • "Breaking" the game will still be possible, especially with the large number of new items. Edmund wants to avoid "breaking" the game in terms of crashing, however.
  • Edmund wants to balance unfair rooms and "ham-fisted" bosses that depend on the player's items rather than their skill. He said that he originally wanted The Binding of Isaac to be more of a bullet-hell style game, but it lagged Flash too much, resulting in the current Binding of Isaac.
  • There will definitely be more Challenges in the game, such as an All-Champion run.
  • Items:
    • Edmund likes The Candle how it is, but he plans to move it into the higher-priced Shop item tier. It could also be balanced by increasing the cooldown time.
    • Edmund considers Lemon Mishap to be the joke item of the game, so he doesn't want it to be over-buffed. Still, its range and duration will be increased.
    • Brimstone will not be changed, but the "Brimsnapping" glitch will be fixed.
    • The Kamikaze! glitch will be fixed, but the item itself will be buffed, probably by reducing self-damage.
    • Dr. Fetus and Epic Fetus will remain the same, but will simply be harder to find. Epic Fetus could be unlocked in a harder challenge, too.
  • The "Faith" stat will actually be in Rebirth, probably increasing the chance of an Angel Room appearing.
  • The Stats in the pause screen will not be any more detailed than they are currently, because Edmund does not want players to see the exact stat numbers. The bars themselves will be less confusing, though.
  • Edmund says that he does want to balance the characters, but not in terms of their stats. Certain characters being harder to play is supposed to be a part of the game.
  • The Mystery Man is confirmed, and at least one more character will be added.
  • There will be no items referencing famous people in the Binding of Isaac community, because Edmund doesn't want people to feel left out for not getting the reference. He also says that it feel like breaking the fourth wall, and is unnatural.

November 27, 2013 (Update #28)
