How do I unlock the playable character Judas? As the unlocking requirements are unknown. What exactly are the unlocking requirements?


You can unlock Judas by first beating Mom, which will unlock two new dungeon levels called "The Womb". Then you have to beat The Womb, by killing the boss Mom's heart.

  • i beat mom and havent beat the womb but i will say some tips. 1:watch out for devil rooms,example,3heart items when you only have 3hearts isnt a good idea it will kill you 2:tri-shot is effective,if you have a choice,take it 3:the pact in devil rooms doesnt do anything! it turns your charecter black and takes you down 2hearts depending where you get it 4:the dead cat gives you 9 lives always go for that in devil rooms 5:if you get a judgement card and use it,or find a homeless person with a cent sign,give him money!one fatal mistake is NOT giving him money sometimes he gives powerups most time – user13055 Oct 9 '11 at 20:35

    @Dogarr: Allow me to point out some inaccuracies: 1. You don't have to be afraid of devil rooms, just think whether or not the items offered are worth the heart cost. 3. The Pact increases your damage and range by 1 (so unless you have those maxed out, it does do something). 4. While The dead cat (Guppy) gives you 9 lives, it lowers you to 1 heart, and you start each new life with a single heart as well. That is not necessarily a good idea. – Aubergine Oct 9 '11 at 22:05
  • If you only have one heart left and buy Guppy, you will die, and use your first of your nine lives, always thought that was kind of funny – Timothy Roy May 31 '12 at 14:56

There seems to be an answer to this in the Steam achievements of the game. First, lets look at a couple of achievemnts that seem to support this guess.

Maggys Wig Collect 7+ container hearts in one play through
This is the requirement to unlock Magdaiene. (As I recall it. Could have been less.)

Cains Eyepatch Collect 50+ pennies in one play through
This is almost the requirement to unlock Cain. (The actual number is 55.)

Thus, I feel it's reasonable to assume that the requirement to unlock Judas is connected to the achievement

Judas's Fez Complete the full game

What exactly this means, I do not know, as I haven't yet beaten Mom.

And looking at the achievements it seems that just beating Mom isn't enough.

to unlock judas you need to kill moms hearth-use we need to go deeper in dephts II or kill mom and the next time you play the game when you kill mom a trapdoor will apear taking you to the womb. The best way to get there is to search every room, give money to beggars or blast them to increase the chances of meeting the devil

    What does this answer provide that hasn't already been said? – Frank May 31 '12 at 15:02

If this helps I unlocked him by killing "satin" to get to him you have to kill "moms heart" and a room will appear in the room with the large gold chest after betting her, keep in mind its realy hard. if possible use "Azazel" he is a bit overpowered.

  • Binding of Isaac: Rebirth is a different game from the original Binding of Isaac. This question is about the original game. – Studoku- Reinstate Monica Feb 11 '15 at 14:22

I believe killing blue baby or Satan (IE, beating the game) will unlock Judas as a playable character
