Some of the enemies from this mod are actually in Fiend Folio
Oooo I cant wait for the up to date version to be out.
Tho rather than afterbirth+, you might wanna consider waiting for repentance then porting it.
I cannot seem to download it fully, what I mean is that it will not be in my issac game when i press download
this could be the new antibirth

we need hutts to see this mod
It didn't work. Using afterbirth. Help me.
So...I used a rar to zip converter because I haven't the slightest clue how to use 7-zip, but when I did that and opened the agony folder...there were no folders inside, just several pngs of already existing items and a READ ME. Did I do something wrong?
No, you just have to ccopy and paste all of those into the resource folder
wait...WHERES THE REBIRTH VERSION help i just want this mod.
Does this work on the antibirth mod?
do i have to uninstall aftirbirth to play this mod?

hi does any one know how long until ab+
Truly one of the best Isaac mods out there.
I feel like I might be doing something wrong, but I haven't been seeing too much of the new content, aside from 2 new room layouts and some spider web enemies on the first floor. If I haven't done anything wrong, then I would highly suggest adding more, I don't know how to explain this, encounter rates? for the new stuff, other than that, mod is great
Look's sick! I love the bag heads!

It's a nice mod, though in greed mode, sometimes the white dips spawn and it's impossible to kill them there. The main game is still fun to play in your mod.
how do i know if i am downloading the rebirth or afterbirth version of the mod

It says theres a rebirth version in the description. If you can find where the rebirth version is please tell me. I want to play this mod
I love this and had no problems with windows 10!
I really liked the mod, but some new sounds for the new enemies would be a good addition, also, please don't change the title logo
I also want to know if it works for Mac...
It probably does. I'm on mac but i have rebirth. I'm just wondering where the rebirth version is.
Hello! This mod is looking amazing, and I even played it on Afterbirth. But will you port your mod on Afterbirth+ ?
in the mod description the creator said he will port it to afterbirth plus
mine downloads rar shortcuts and wont work what do i do
Does this work with God Mode like in rebirth?
This mod is the only other mod alongside Antibirth that I think deserves to be added into the actual game.
make the afterbirth+ version here, please.
When is the Afterbirth + update coming?


The new version will take a lot of work, be patient!
A rebirth compatible version is available yes
difficult instructions in the README but it crashes when i start a game.idk what i did wrong but i'll explain more if i get a reply
Starbolt yes this is Afterbirth and rebirth. It also states in the description of the mod that this is both, and he is working on afterbirth+
If anyone wants to know, this kinda does work with AB+. I tried it with Greedier mode and Apollyon. New enemies were in greedier mode and Apollyon worked, but after a while it did crash. I only tried it for about 5 minutes, but it did work as far as I could.
Update, played for about an hour with a couple of mods like the heretic and infinite item charges. The heretic crashed the game after a minute or 3 and infinite item charges works pretty okay, but will still crash but not as often(In 1 hour of gameplay, for me it only crashed twice). Also some tears affects from AB+ might be invisible, but still do damage like the Apple! tears and also some familiars like depression were invisible, but still left a trail of tears. Might try to make the tears and familiars visible, but not sure.
I'm waiting till it's gonna be compatible with AB+ ;)
Please tell me you are planning on porting the main features of this mod to Afterbirth+'s new API? It's hard to go back to not playing Isaac with this mod.
Wondering will you port this to afterbirth+ modding tools ?
This mod STILL doesn't work with Afterbirth sacrifice rooms. I've lost too many opportunities to fight Mega Satan because sacrifice rooms don't spawn angels, which drop the key pieces. It's such a shame because of all the great content, but it's the only reason why I refuse to play Agony of Isaac. Consider patching this bug soon.
Plus, the seed is irrelevant, because it'll happen no matter what, but here it is anyway:
XK2Y HSW7

Look for the sacrifice rooms on Womb/Utero I or II - I can't remember - and one on the Cathedral.

As for screenshots, don't know what there is to see. Not having Afterbirth sacrifice room effects is something that *doesn't* happen.
But again, here's one anyway:
http://imgur.com/a/vISZe
I had an error when fighting this centipede boss I don't know what its called because it said it was the dark one. Is that just an unchanged file or a bug? The seed is TGJ2 N0VW.
i did everything right it does not work!!!!!
I had the same problem ;) But You know Savior mod? Even if this mod won't work, Savior mod still can be used.
this mod is one of my favorite mods on this site! I just LOVE IT SOO MUCH!
I downloaded this mod, installed it but it dosen't work :c I mean - i hadn't see nothing new. What should i do? I specially bougt Isaac on Steam for this mod.
Will this mod be getting compatibility with Antibirth? Or are they already compatible? I'm curious.
"Both Afterbirth and Rebirth support!"
he said will it be compatible with antibirth not afterbirth
That was the point. Antibirth was not listed there.
i just want to know how to make my own rooms
OMG YAS I CAN FINNALY PLAY WITH MY NEW..MODDING...POWERRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRS (opps btdubs absolutely luv this mod cuz MORE FREAKEN STUFF)

i was walking around the room for ages trying to kill a stone mulligan not noticing the doors were open
#fail
hey does it work with afterbirth?
hey does it work with afterbirth?
I can use the rooms of the Agony of isaac to my fashion? (The Binding Of Wisnia)
https://moddingofisaac.com/mod/2013/-the-binding-of-wisnia-
This mod is pretty cool :P i like it alot. Really cool. Much WOW, Much Good.
I have seen 1 new enemy but nothing else. This mod is lacking a bit.(Or i just haven't gotten far enough to notice)
I was expecting a complete overhaul, but the game looked mostly like the original. I saw 1 new boss and a few new enemies/rooms. Will keep playing, see how it goes.
Been playing with this mod for nearly a day now. I absolutely love it, and the challenges it adds. The Eternal enemies from the original Binding of Isaac's free DLC are an awesome touch too!
Does this mod affect greed mode too?

Really cool dude you keep updating it?
This is an amazing mod! Adds a new layer to people who have grown tired of Vanilla Isaac and reskin mods. It's like a new, free expansion to Isaac!
So http://4g1e6i1s5t.tumblr.com/ isn't working . J?? still have tumblr?
If I haven't unlocked everything in the game, do the new bosses conflict with the item unlocking?
If you have another mod downloaded, and you download this one... will this mod override the other one?
It depends how you install it. Depending on what mods you have installed, you might run into a problem where there are folders that have the same names from the mods. If this happens, just move the files from one of the folders into the other folder so that it has the files from both folders, and you should be fine. I will say, do NOT just keep both of the folders in the resources folder with one of them saying (folder name here)1 or (folder name here)2. If there are multiple files with the same name, unless you are really good at modding and can edit the files so that it is making both mods work, then you are out of luck.
Bug Report -
Playing as Lilith. Basement II.
Seed: DZDG P1YM
Bug: Cannot progress from Basement II to Caves I. I have never had an issue with this mod before this and I've been playing it for a couple days, and in those days have had plenty of runs. My character jumps into the trap-door, and I get the pop-up error: 'isaac-ng.exe has stopped working. A problem caused the program to stop working correctly.'
I haven't done any game breaking (this run). The boss for Basement II was Monstro.
Thank you very much!
rar is just a compression thing. get 7zip or winrar, something like that, to uncompress and use the mod. elsewise, everything would just be really tiny >.>
really nice almost like a new dlc
Nice mod, but it's a bit simplistic. Edited starting characters would be nice, and re-textured floors. But I love this mod and all the new challenges it has set for me
Well, its purpose is to add new enemies and rooms, not to be complete overhaul. Plus you can use it to make your own mods under certain conditions (FAQ) so that would probably interfere.
I remember that there was a mod compatible with TAoI, but I don't remember what was it... if you ever know ?
This mod is beautiful and great
Started playing this mod today and really enjoying it so far! will be good to use whilst waiting for Afterbirth +
why not compatible in rebirth?

Q: Afterbirth?
A: We feature the Afterbirth and the Rebirth version of our mod in the download. Be sure to install the correct one!
Очень крутой мод!
This mod adds alot of new content, I love this mod and I prefer it over godmode, because of I dont want too much additions, and this mod adds just enough for me! c:
god damn this mod is as good as SE- I mean eating after starving for a day
Жаль что мод не добавляет новый вещей(9( а так то мод супер! / a pity that does not add new stuff, as well as the great (translated in Google Translate) 0))
Какие вещи вы имеете в виду?
Именно НОВЫХ вещей
as a quote from heavy," I have plan for u more PAINNNN! 11/10
still an amazing mod also i nearly had a heart attack seeing the weird flying spider "DONT GIVE IT WINGS!!" I said love the mod
This mod is really creative and enjoyable. (ALSO PAIN)
How do i get to the blind and the ather
1000000000000000000000000/10
It seems your added Glitch gapers and huggers doesn't do their... "chasing" animation (the face-changing animation)
I was wondering... Is there a wiki or something about this mod, in order to gather infos about the new elements you implemented? If not, it'd be nice to have one... Anyways, great mod!
This is literally my favorite mod of all time!
Drop the "resources" folder for the appropriate version into your game folder (%SteamRoot%\SteamApps\common\The Binding of Isaac Rebirth\) and you're good to go!
i have a pobrlem can not play the mod plz help me
are you doing everything right
Mabye the porblem can be fixed by first extracting the mod then copy n' pasting the contents of the extracted folder and putting them in the resources folder of The Binding of Isaac. (Resources folder on help)
im crashing even tho i have put the afterbirth folder into the res for my game??? is it because im useing the savior mod?
Yes, it's probably because of savior mod.
Sometimes, in the greed mode, enemies (little dump for exemple) appear in the right corner. They are completly invincible and blocked here. They deal damage but we can't kill him. Does anyone faces the same issue ?
Provide seeds please, to help resolve the bug quicker.
is it able to add new items in this mod (in any mod btw)?
No, it's not possible to add new items
Afterbirth sacrifice rooms are broken. No blessings or angels for me to get to Mega Satan.
Could you provide some seeds and/or screenshots? I wasn't able to confirm this.
Could this corrupt my file? And if I just want to play the game normally without the mod, what do I do?

Sorry for the stupid questions...
The chance for a mod to be posted as malware or a virus is extremely slim, especially considering that this mod has thousands of downloads. Basically, this mod is not malware, and if it is, it will be deleted.

If you do not want to use the mod, remove all of the contents of this mod from your resources folder. If you need more information about how to use / install the mods, add me on steam: dragonoidslayer

I made a video of the mod
https://www.youtube.com/watch?v=zRbVG3dGgS8&list=PLnqNw6_DXWFvPi2lPq106bDI6Qj2sycIw&index=18
Just Started Playing This, Good Job So Far!
can someone help me install this mod
I'm having issues with some enemies being completely invisible. The only way I can know they're there is from the fact I can see their shadows. This seem to be random, as from the sound of the monsters they appear to be different ones. Might be worth checking into.
Have you updated the mod from a different version or was it your first time playing the mod?
When I first downloaded this mod I wanted to have a bad time but instead I got incredibly lucky and got loads of OP items. Dark One was hard though.
no mods are working it says I don't have the game even if I do
can you put a alternate link for the mod because i have non-steam rebirth
Do all the little spiders do damage and I was incredbly lucky for 2 min ?
Nope, the small spiders don't do damage
Never ? So they have absolutely no use ?
They're mostly there for decoration and annoyance. They can block your tears sometimes.
Why not? Rar files are the same as zip files but with better compression.
Every time i do a rar file it makes me have like 100 new tabs of the same thing.
Just Saying like the file name and stuff.
I have no idea what you mean. Just extract with 7-zip like any normal archive file.
Tez forgot to mention that in 1.6.2 the BR Patch was updated.
um, whenever I try to play this mod on its own, (and yes, I do use simple mod loader.) when the title screen comes up, it just says Afterbirth, and not the Agony of Isaac, please help!
Please read the last sentence in the "Notes" section.
well, I feel like if I install WinRAR, ill get a virus.. and I always have trouble installing them with a rar file..
Well you'll have to get it if you want to play the mod. WinRAR is completely virus free if you get it from the official source. If you are still concerned, check out the FAQ section, I linked to the official site of 7-Zip there (I'd recommend 7-Zip over WinRAR anyways since it's free).
actually, I have 7-zip at my dads, but I need a tutorial on how to do this with Rar files... because even though im 15, im not really a computer expert....
Do I have to send you a "Let me google that for you" link, or can you actually google it yourself?
how would you like it if I said that to you? how disrespectful!
I probably would have been like "Oh, that's rude. But the solution to this was so simple, why did I not come up with that?".
I mean, first it didn't seem like you read the post and then you ask a question that would have been answered in 10 seconds, if you used a search engine.
Yes, I could have expressed it nicer, but I didn't and I can't change it now anyways.
Maybe you don't have knowledge but please don't make me think you are not intelligent. Extracting .rar files using 7-zip is exactly the same as extracting .zip files.
really? it is? well that's easy!
This is disturbing in many different ways...
Love these kind of mods keep up the good work!
I find it quite funny, just increase but the appearance of new mobs and lowering of vanilla
Did you add any new items? Because this interferes with my Clearer Item Descriptions mod.
No Agony doesn't add any items and I tested it, it works. Maybe try reinstalling both mods?
It's both Rebirth and Afterbirth!
It's not working for me, should I tinker with the "packed" folder or something? Whenever I start the game, it just give me the normal stuff.
I've got it down. My problem was that I put the mod resources folder into the original one, instead of replacing it.
I really wish that this mod would make the bosses and enemies that are added in this mod more common than the ones in the vanilla mod, like the Heretic mod. then we could see all the new content this mod has to offer!
The bosses that are new don't even show up it just says monstro or famine then the new boss starts. Can that be fixed?
Sorry, but we can't add boss splash arts for our bosses. That's because we don't overwrite any bosses, but add ours and that makes it impossible. Maybe Afterbirth+ will give us a solution to this.
Good monsters!VERY good monster!
I liked the battle against the new Haunt boss and all but how the hell do I advance to the next floor? Sorry, don't have the seed, I traveled and tested the mod on my free time (offline) so I didn't know I needed the seed for reporting a bug. Anyway, great mod, enjoyed it very much.

http://imgur.com/yBCv1QM
Thank you for the report. Should be fixed in 1.6.1
you also put the extra awesome because word limit
I had to put best mod ever because word limit.
Still one of the best mods I've ever come across on this site. Thank you for the work you put into making it!
where can i see if its the rebrith or afterbirth version?
One Folder in the archive says "Afterbirth", the other "not Afterbirth"
Does this mod remove some of the normal Enemies,Bosses or Items from the Game?
Take a look at the FAQ section of the post.
IGN gave loZ skyward sword a 10... That alone proves any score or review by them is worth less than the ashes of a dog's incinerated shit
IGN gave loZ skyward sword a 10... That alone proves any score or review by them is worth less than the ashes of a dog's incinerated shit
They both basically said the same thing so why not
Any chance you could release a "lite" version with just the Eternal enemies?
Thanks for your time!
Sorry, but we probably won't release a version like this :/
I am a bit of a noob when it comes to mods.
can someone please tell me how to make this mod work?
I have already downloaded the .rar file? what do I do now?
Please read the post. I didn't rewrite and make it look better for nothing.
Right-click on the rar file to open the context menu, select 7-Zip and then "open Archive"
This mod is really buggy with the new bosses. First of all, they don't have a splash screen, I know now that Monstro is replaced with Ather, and Loki is replaced with The Blind. Ather kid, Ather's bud, doesn't move often, and when he does, His animation shows him flinging up into the air then come back down and lay down for a few seconds, and repeat. The Blind is even worse, he always spawns on top of the boss room door, and moves side to side, which obviously you just took the creeper AI and used it for this boss. And to add insult to injury, his animation of him is clunky and glitchy as all hell, plus, it's fingers and The Blind itself, is floating in midair, when it should be on the wall. Please at least get this fixed and try a bit harder on the bosses, but the enemies are totally fine and really creative, so in conclusion, keep up the work.
Sorry for the typos, I was in a rush
Thanks for the report. We can't do anything about the splash screens, because we don't replace bosses, we just added them and Agony's bosses are sometimes use more than one Vanilla boss room id. We'll try to fix the bugs with Aether and The Blind as soon as possible. If you could provide some seeds with these it would help us a lot.
With the release of Afterbirth+ a lot of that will be fixed most likely
Hey, can I install this mod with the "Varying Special Rooms" mod? I don't know how to uninstall it.
You "could", but the Varying Special Rooms would overwrite Agony's special rooms, so you'd have no custom bosses.
Dodge, just go to 'resources' folder from 'common' from 'steamapps' find the mod, and delete the extracted one. And the .rar or .zip
I love this mod, it adds a load of more variety.
Is there a way to add boss art for each of new bosses?
Not yet. We need to wait for Afterbirth+ first.
This is probably a dumb question, but when you say there's new enemies and bosses does that you mean you've replaced existing enemies and bosses, or somehow added new ones?
He added new ones. I don't know anything about coding, but he did add new enemies/bosses.
Really great mod! One of the craziest mods out there! It's really hard though...
Hey I do not have Afterbirth, can you put a link for an earlier version?
The rebirth version is always included in the download.
I don't meet new enemies after I reach the caves...
amazing mod love the sack headsXD
Am I screwed? I installed this mod awhile back, and I uninstalled it yesterday. Everything is back to normal, except I'm still getting champion enemies that shouldn't be champions: Swarm flies that explode like Tammy's head when killed, regenerating Dips, Exploding Champion Dips (the dark gray ones).

I removed the proper folders on installation (I'd uninstalled it once before awhile ago, and everything was fine), so I don't know why these champions are still appearing.
Well, correction, I didn't delete everything in the resources folder besides packed. There's an XML doc called "entities2", but that was last modified 2/13/2016, and I uninstalled this on 2/29. That and I think the entities doc has been there even before installing the mod.
Welp, there's your problem
In the entities2.xml are ALL entities and their tags. Because you didn't delete this file, some enemies still have the champion="1" flag set. It's safe to remove the file.
Hmm...okay. I'll go ahead and delete that then. I'm just confused, I never deleted it before, and the game played fine. Oh well. Thanks!
I wish the props and the new stone enemies were more common...
looks good but will it work? hopefully

Hey! We have a new Discord server. You can find more information in the announcements channel there. See you there!
