Version Information
Steam Patch Notes
Official update history
Happy Spring!
The Isaac team has been working hard and is happy to debut crossplay for Repentance+ Online PC. As we work to make the feature more seamless, we could use the community's help to give things a test.
For now, crossplay can be enabled outside of the game in the OPTIONS.INI file. By default it is located here: C:\\Users\\YOURUSERNAME\\Documents\\My Games\\Binding of Isaac Repentance+
The last line of this file is "EosCrossplay=0" You can change the value to enable or disable functionality.
0-1: Crossplay is disabled. You won't see any change from the experience you are used to.
2: Crossplay is enabled. Public lobby results you see can either be from Steam or from Epic.
3: Crossplay enabled + EGS account linking. If you set this value you will be asked to link your Epic account on startup (unless you've previously linked it).This setting also gives you access to both Steam and Epic friend lobbies and anything provided by the Epic social overlay (achievement viewing, friends list, inviting Epic friends, jumping directly into Epic friends lobby, etc.)
We have also added a mute feature for online chat. In the text chat, you can type /mute (username) and /unmute (username) to stop and start seeing messages from them. You don't need to type the entire name, /mute zombo for instance, will mute me for good until you unmute me. Or maybe you want to mute Ken…
As always, please report any bugs you find to [email protected] and we look forward to playing with you all online! Be sure to say hello on X or something,
Also, enjoy this super 4K HD image of Edmundo, weird that the last part looks like a 2.

We've been hard at work on the next patch for Repentance+, and there’s a lot coming your way. There are loads of bug fixes, optimizations to online modes, balance tweaking and feature improvements that we hope veteran and beginner players will both appreciate.
Here’s one cool addition that you can look forward to. You know how the Key Master and Bomb Beggar often get overlooked, because you don’t want to use up too many of your resources to keep gambling for their big payouts? Well, pretty soon you’ll be able to pay them with a golden bomb or key to receive their item payout instantly – at the cost of that golden status, of course. There are some more changes in store that I can’t tell you about just yet, but please look forward to the next update.
Some of you may have seen us messing around with AI-controlled Isaac over on my Twitch stream. We’ve enabled chat commands, where viewers can make Isaac move to specific spots, attack, bomb and use his active item, all through Twitch chat.
It’s been fun watching the community try to complete runs together. We’re working on more ways for chat to interact and team up. If you have specific commands you’d like to suggest, please let us know. More to come on that, too!
Now here is Edmund to talk a little bit about a project that’s near and dear to his heart: his next game, Mewgenics.
--------------------------------------------
Edmund here. Sorry for hijacking the Isaac blog. I promise to only do it one more time.
So, for those of you who don’t know, I’ve been working for a very long time on an endless cat-breeding RPG called Mewgenics. If you love Isaac, you’re going to feel right at home in this one.
Mewgenics is built with the replayability, randomization and strategic depth that made Isaac so addictive. It has branching paths, tons of items, spells and mutations to discover. The game genre is completely different, but it’s designed to keep you coming back again and again, just like Isaac.
Mewgenics actually takes place in the same town where Isaac and his mother lived. So if you’ve spent any time getting lost in the lore of Isaac, there are definitely some cool connections to watch for. And the soundtrack by Ridiculon is the best they’ve ever done.
If you’re someone who loves the challenge of Isaac’s endless replayability, and enjoys unlocking new items and exploring new combinations, I really think Mewgenics is going to scratch that same itch.
There’s an absurd amount of depth, and you can easily sink hundreds of hours into the game without seeing everything we crammed in there. It’s got the same charm, the same humor and the layers of complexity you’ve come to expect from my stuff. It really feels like the culmination of my experience making games.
If you haven't seen the Mewgenics trailer I just released, please check it out and share it with your friends and family. I think you’ll be pleasantly surprised by how familiar it feels, even though it’s something new. Go add it to your Steam wishlist and get ready because it's finally coming!
Alright, that’s enough from me for now. Stay tuned for the next Repentance+ patch, and keep an eye out for more updates on Mewgenics!
And here's the link ONE MORE TIME!

See you online, xoxo.
Herro, it is I Tyrone. As promised, the new Repentance+ free DLC update is here, today, now! You’ll need all the previous DLC to run it.
This is a full-featured release, but we’re calling it a Beta still, because we’re still looking to refine things and squash any remaining bugs. You can do your part to help us by reporting any bugs, desyncs or crashes to [email protected] with the subject line #Repentance+Beta v1.9.7.4
{STEAM_CLAN_IMAGE}/6743820/cdd5bf5495040a851a21f2d88c5cbe555006a6b8.jpg
Please Include the version number in the subject line and be as detailed as possible when describing the issue. An example of a bad bug report would be “I crashed when fighting Monstro.” A much more useful explanation for the devs would be “In an online match with 3 players, I crashed when I used Crack the Sky during the Monstro fight.” Include the seed if possible and your crash log that can be found here: Documents\My Games\Binding of Isaac Repentance+\crash_dumps. This helps us greatly in focusing on the issue at hand and getting it resolved quickly.
If you played the Isaac Online Alpha back in January, you already know how some of the online stuff works. But a lot more features have been added since then, including support for all game modes, lots of filtering options (when creating or searching for an online match) and a new emote wheel (press the left Alt key or click the Right Stick on a controller to access it). We even added separate “group” leaderboards for online Daily Runs.
And that ain’t all. Look for lots of balancing adjustments and item upgrades—all buffs!—that’ll turn some of your least favorite items into some of your new favorites. Details in the changelog below. Also, some Commonly Asked Questions below (Edmund calls them CAQ, rhymes Ipecac!)
We’re going to have lots of fun playing Isaac online together. See you in the basement!
{STEAM_CLAN_IMAGE}/6743820/47b44b3171810c1001e348f2e4a191d8334bd65c.png
Q: What can I do online?
A: What you do online is between you and your webcam. But as it related to Isaac, you can play Normal, Hard, Greed, Greedier or Challenges as well as Daily Runs and seeded runs with up to three friends or with strangers.
Q: Can I earn achievements in online play?
A: Yes! All unlocks that can be earned in solo play can also be earned online. Be aware that you’ll have to be in a match from the beginning in order to be eligible for unlocks; joining a run in progress does not allow achievements to be unlocked.
Q: Are there things in online play that don’t appear in solo play?
A: Online play has a few differences from solo play. Defeated bosses will drop an item for each player in the match. If a match is joined in progress, the new player will be granted several items to catch them up based on how far along the run is. Players can spend coins at the revive machine in the starting room of each floor to bring back dead players. Be warned, however, that the cost goes up each time the machine is used. Defeating a boss at the end of the stage will also revive any dead players. There might be some other special things to discover online as well!
Q: Do I need the online achievements to unlock Dead God?
A: If you have not yet completed your Dead God file, you will need the online achievements in order to get it. If you already have Dead God, you will not need the online achievements in order to keep it.
Q: Can I play with mods online?
A: No, all mods must be disabled and the game restarted in order to play online.
Q: Where are my mods?
A: Repentance+ has its own mods folder located here: C:\Users\YOURUSERNAME\Documents\My Games\Binding of Isaac Repentance+\mods however, it is empty. Mod creators will need to update their mods for compatibility. If you copy Repentance or AB+ mods into this folder, you DO SO AT YOUR OWN RISK as things are likely to break.
Q: Did anything change in solo play?
A: Yes! There are many item improvements and reworks to experiment with, and many fixes and quality-of-life adjustments made to both solo and online play.
Q: What if I desync or find a bug?
A: If you encounter any issues, please submit a report! Send an email to [email protected] with the subject line: #Repentance+Beta v1.9.7.4 (or newer if you are on a more current version)
Be as detailed as possible in your report, including what occurred and when, a seed, what items players had and any relevant files.
Zip the desync log found here:

Crashes should generate two files, a .txt file and and .dmp file. They are located here:

CHANGELOG
Item Changes:
Tammy’s Head - Reduced the duration of the animation when using Tammy’s Head, allowing Isaac to fire more quickly after use.
Lemon Mishap - Slightly increased the size of the puddle. Also, the puddle will now persist until Isaac exits the room.
Mega Bean - Creates a catastrophic fart that sweeps the entire room.
Milk! - The familiar now follows closely behind Isaac and blocks shots. After 10 hits, the glass will break and give Isaac a Tears upgrade for the remainder of the floor.
Delirious - Summoned bosses will now persist through rooms. Only one boss can be active at a time. The charge is now variable, based on the quality of the previously summoned boss.
Jar of Wisps - Reduced to a 6-room charge, allowing the wisps to stack up to the maximum number more quickly.
Abyss - Item quality now impacts the damage of the summoned locust. Locusts now inherit many different effects based on the item destroyed by Abyss.
Flip - Charge has been reduced to 4 rooms for Tainted Lazarus only.
Portable Slot - Removed from the Shop pool. Added as a possible reward from slot machines.
Void - Charge has been reduced from 6 rooms to 4.
Epiphora - The Tears upgrade from firing in a single direction is now a smooth increase, instead of being staggered every few seconds.
God’s Flesh - Doubled the chance of shrink tears firing. Shrunken enemies now briefly flash white before growing back to full size. Enemies that explode, fire shots or summon minions on death can no longer hurt Isaac if they’re killed while shrunken.
Hushy - While held in place, Hushy now fires radial bursts of shots.
It Hurts - After taking damage, Isaac’s tears will now leave behind small pools of blood creep for the room.
Mars - In addition to being invulnerable when charging, Isaac will gain a 1-second bubble of invulnerability after the charge. Hitting obstacles also causes a knockback effect to clear any threats from the surrounding area.
Evil Charm - Isaac now gains immunity to spider-web slowdown, flame attacks, fireplaces and poison mushrooms. Isaac can also stand in enemy creep for 1 second before taking damage.
Vasculitis - Friendly radial shots fired after killing an enemy will now appear as blood clots to more easily distinguish them.
Lil’ Portal - Has been completely reworked. Double-tapping a fire button is now required to launch Lil’ Portal. After it has consumed enough items and the room is clear, a single portal will spawn and the familiar will now disappear for the remainder of the floor. Entering this portal now takes Isaac to a room where he can pick up or drop off items. This room persists throughout the rest of the current run.
Linger Bean - The fart cloud is now deployed after 4 seconds of continuous fire (instead of 7 seconds). The cloud starts small and potent, and will grow and deal reduced damage over the course of 10 seconds.
Jupiter - Now heals 2 red hearts instead of just ½.
Butter Bean - Recharge time has been reduced from 3 seconds to 2.
The Bean - Can now be re-used after a 4-second cooldown (instead of a room charge).
Kidney Bean - Can now be re-used after a 4-second cooldown (instead of a room charge).
Dead Bird - Will remain active between rooms as long as the player is at ½ heart. (Note: Eve requires 1 full heart.)
Data Miner - Using Data Miner in a room with an item pedestal will now reroll it into a glitched item.
Fixes:
Bomb rocks can now create bridges across chasms.
Fixed a bug where Technology 2 and Mom’s Eye could cause backward-firing shots to do excessive damage.
Fixed an issue with the D4 unintentionally being able to force all items in a particular pool to reroll.

Increased the shadow size of Ultra Greed's coins to make them easier to see when falling.
Ultra Greed's coins can now be devolved into coin pickups using the D10.
Stone Eyes now do a full turn before they start firing their laser. (This prevents some unfair damage scenarios when entering a room from the bottom door.)

Added Skeleton Key, Best Bud, Angry Fly and Sharp Key to the Key Beggar's prize pool.
Fixed several items that were missing from Greed Mode's item pools.

Added a SMALL amount of boss armor to ???, The Lamb and Mother.
