Questing of Isaac
100+ New Challenges
Created 8 months ago
Isaac has no escape from his nightmares so he might as well come to accept who he is and what he has done. Even if that means killing every last shadow in the darkness of his adolescent mind.

To do that, he must beat all the challenges...or as he likes to call them...Quests.

All 100 and counting all just to slay maybe.. one demon.

Are you up to the quest?

Can You Make a Version For this in Rebirth Even if it has less of the Challenges?!
I have Afterbirth+ and can't get this mod to work - I have tried to extract the data into the resources folder, but no effect. Help?
This is amazing
i have not done all of them but they seem not too easy and not to hard.
You need afterbirth+ to play this mod. Antibirth is a rebirth mod, this mod is a afterbirth+ mod.
these aren't really challenging challenges
Not all challenges are supposed to be difficult.
But isn't the definition of challenge to be hard?
You need to explain your problem first.
Looks very promising, but I guess we all want to see more details about the challenges.

A new animated Planetarium theme (from Antibirth) is now available!

There is a new DLC search filter on the Browse Mods page.

Added the 50 new babies from Afterbirth+.

The What's New sheet will try to get your attention when there is a new site update.

Fixed some mod icons not changing after being updated.
