True Co-op
Co-op babies begone! Play as your own own individual characters!
Created 6 years ago
(REQUIRES AFTERBIRTH +)

With up to four players, select your own individual characters, and have fun! You can pick up your own items, trinkets, cards, and pills, instead of having to share with player one!

Configure a number of different factors of gameplay, including enemy HP scaling per-character, player ghosts, and more!

A fun new challenge is available! Play with multiple characters at once-- at the same time! Painful, chaotic fun! I mean...long live the hive-mind!

Q / A



I remember in Antibirth, the game was bugged so you couldn’t resume with a co-op character! Does this mod done by a completely different development group somehow have the same issue?
Nope. So long as the mod is enabled, all of the data for the additional co-op character will be saved-- just be sure to join in the proper order. If you don’t, just exit out and try again or swap controllers.

My friend is a ghost!! What do I do?
Find a Devil or Angel room-- you can resurrect them from there.

Mod characters!! I want mod characters!!
We offer the tools needed for proper mod character implementation, but it’ll have to be done on the side of character creators-- if you want your favorite modded character compatible, ask the creator if they can do compatibility.

This is confusing! Who is who?
If you’d like to see who’s who, hold down [TAB] to give off a colored tint on each player. If you want this tint on all the time, plus specially colored text indicators, there is an option to change it in the config.

Screw being a ghost! When my partner dies, I want everyone to feel it!
No problem-- we have a few other options for death in the config: the run ends when someone dies, a player dies and re-spawns as a ghost unable to be resurrected, dies and spawns as a ghost with the ability to resurrect in sacrifice rooms, or dies and spawns as a ghost with the ability to resurrect in devil or angel rooms (on by default).

You keep talking about this config, what’s that all about?
We actually made a challenge that allows you to customize how True Co-Op works, allowing you to change such options as the HUD, how players are resurrected, and more. Press R to exit the challenge.

Something something ONLINE CO-OP
No. Online Co-op is not feasible with a mod using solely the Afterbirth+ lua API.

Your mod breaks my mod! How can I fix this?
Directly below the Config table in main.lua is a blob of useful information for ensuring compatibility with True Co-Op! Feel free to ask questions to DeadInfinity#5189 (meowlala) on Discord if you need clarification.

- Forgotten Update Patch:

- Forgotten player one ghost / revival support.

- Minor fixes relating to bone hearts.

- Custom Co-op Boss Splash & Booster 5 basic support. The new character unfortunately cannot work with co-op as player 2-4, but this should help with many of the crashing issues.

WHY THIS DONT WORK FOR REBIRTH YOU GUYS HATE REBIRTH?????????????????????????????????
everyone hates rebirth ig,no one likes it and theres almost no mods for it,gee i just wanted mods :C
how do you do multiplayer in the first place
what if my friend starts as a ghost, do i need to resurredt him right after starting?



if you have friends to play with this is sick no lie
Seems like a cool mod,i just need friends that have the game now
I played this mod with my friend SO COOL

its cool i like playing with my brother
is it online only? or can you also play local?
that mod is awesome it gave me such a nice time with my friend
Crashes on Repentance version 4.0.4, might be because of bad interaction with external item descriptions mod.
no its because true co-op was added in repentance so this mod is for afterbirth+ only
i don't mean to be offenseive but this mod is dead in repentace
This mod is trully great i dont have Repentance but have afterirth and afterbirth+ it rlly heps when i wanna play with friends!!
Welcome to the Repentance! Thank you for more hours with my friends in this mod
Congrats on getting it into Repentance!
I wish this worked for the binding of isaac rebirth/afterbirth

The solution is: go into Steam Workshop and download it from there.

For everyone complaining about the mod not working even after the installation process is done correctly.

link:
I have downloaded it from there too it make my game just crash even if it is the only mod active
i need the dlc!!!!!!!!!!!!!!!!!111!! smh
is it possible to use the debug menu on the other players? is it even possible
Doesn't work for me. I extracted in resources. When I go on the menu "mods" I can't see anything. And when I play as a second character I only had baby co-op.
is it possible to add join random servers?
is there a way how to do this in rebirth???

i would love to know
Me and my brother likes this mod.
how can i fix that the char menu is not showing up?

It won't show up in my mod's list, is there any way i can fix that?
Super-Dooper-Ultimate Hot. I mean Mod
can i have stats shown for both players?
how to turn on the 2 character because when I connect the controller there is only a small child


1. does it work for consoles
2. is it online
HOW DO YOU PLAN TO INSTALL THIS ON CONSOLE??
I'm havin a few issues downloading the mod. Every time I try it ends up sayin that there is an unknown error type two.
Wow! Thanks for the hard work put into this for the Modder Community, this is really helpful if i wanna play with my friend!
This mod isn't working for me. I may have done something wrong. All I did was download isaac (afterbirth+) and install the mod into the mod folder. Nothing happens when I use a second controller other than I get the player two baby.
I have the same issue too, i found the folder to insert it into and activated it, and i still come in as a co-op baby
All I did that worked is, go to Isaac, open it up, and press shift+tab. Go to the workshop for Isaac and you've got all the mods there as well.
So this version wont work from this?
is this mod workink on the binding of isaac rebirth?
you wrote "now for afterbirth" in the desc. Does that mean there's one for rebirth?
I gave you a heart just to be the 420th. You're welcome.
this is gonna be useful until repentance comes out
it still makes me a baby even if i have afterbirth plus and the mod what do i do
one word HOLYFRICK it's beautiful
hey is there a link for this in 7 zip because I do not have winrar and i really want to play this but as I said, I do not have winrar
COOP in rebirth would be best. I sort of like afterbirth but own it and don't feel ready to buy it.. just wanna play with a friend...
CAN YOU MAKE IT IN REBORTH??? THAMKS.
This Mod Is Very Good,You Can Combine With AI Isaac On My Profile
would it work with the binding of undertale?

Hey guys, hoping someone can help out. Ive downloaded and extracted the mod to the resources folder but nothing is different upon launching the game. Also, no mods come up in that section of the menu, really want to use this )':
it doesnt show the mod after i downloaded it : (5286963341

that's for antibirth (sorry for bad grammar) or rebirth???

actually its for aftebirth + only, similiar co-op was in antibirth
What are the controls for PC? i can't play with my friends until i know the button...
put the mod into the resource folder and yet nothing changes in my mod options while in the game. I installed as normally directed and i also am using the most up to date version of the game which is antibirth +. Im new to this community and usually i can figure sheet out myself but it appears as if this mod does nothing for my system. Any assistance or help would be greatly appreciated and im sure im not the only dude with this issue... or am i.
Is there a way maybe you can make mod characters compatible without the creator doing something? Cause a few mod characters I like haven't even been updated in a while so...
It s cool mods. Афтор молодец и я смог скачать мод использую гайд тут. Если кто не знает то просто откройте для всез в ваших настойках стим и выйдите и войдите через этот аккаунт стим снова сюда!))))))))))
looks cool, gotta keep this mod in mind when i do get afterbirth +
how to install that mod. whats folder i dropped it in resourses and it isn't work


Does this work with Rebirth or WinZip?
what version of the afterbirth+ do you need in order for this mod to work? because right now it doesn't work and in the mods option it says its old pls help.
Sadly For Some Reason It Won't Work For Me... Other Wise I Would Love To Have This Mod!
try restarting the game after enabling the mod. It doesn't work otherwise for me
