Afterbirth Custom Challenge Launcher
Make your own challenge runs!
Created 2 years ago
This is my custom challenge launcher for Afterbirth.
You can create your own challenge runs and share them with friends.

FEATURE LIST:

-Customize starting HP and consumables
-Choose starting trinket and card/pill/rune
-Choose starting items
-Enemy and boss health multiplicator
-Simple item pool editor
-Load/save challenge runs and share them through codes or files
-Random run generator

The item pool editor is a very simple tool which let's you change/combine item pools. For example you could make treasure rooms contain angel room items instead of treasure room items or you could make shops sell devil items AND shop items.

If you find any bugs or you have any suggestions feel free to post them and they might be fixed/included in the next version. Also I'm not a native english speaker, so if you find any GUI text which is bad english feel free to correct me.

INSTALL INSTRUCTIONS:

Just download the binary and start the .exe file. The tool should automatically detect your rebirth folder. If it doesn't it will prompt you to enter the root path of your Binding of Isaac - Rebirth installation.

Modify anything you want and hit the "Play" Button to start the run.

Using this tool may override following files. So it may collide with other mods which are using the same files:

players.xml
entities2.xml
itempools.xml
gfx/ui/minimap1.png
gfx/ui/minimap2.png

does it work with afterbirth+ for anyone else?
It doesn't work for me.
In afterbirth+ you have thing called "console"
nah man, it's an .exe file, so it will run on only if you have wine, or else just run a virtual machine, it should work just fine.
I downloaded the newest custom challenge creator. The program opened normally but when I clicked on "play" it just opened Afterbirth+ without any of my modifications or customizations. Please help - what am I not doing or missing?
Why do my game crash every time i make a custom challenge?

if you get an app called wine bottler it will open the file just fine but you need to direct it to the binding of Isaac steam folder.
