The player now only needs to defeat the first boss in order to complete each challenge. Additionally, the player now spawns with Brimstone and the Guppy Transformation for added ease.

Due to Nicalis' changing how mods are loaded and disabling achievements when mods are enabled via the API, you must unpack you game files and replace the existing challenges file with this one.

How to install:
Navigate to (C:\Program Files (x86)\Steam\steamapps\common\The Binding of Isaac Rebirth and run the ResourceExtractor located in the tools folder. The resources folder should now appear in your Rebirth directory. Rename the folder labeled "packed" to "packed_old" in the resources directory. Overwrite the existing challenges.xml with the one included in the .zip
