Reccomended: Upload your save file before you start with judas, as Judas only has 1 heart you can die very easily. this is the one I used - AP08 77PS (Can be either caves 1, or caves 2)ДЇor this one I would not advice to use a seed. Same for the mulliganboom you can use a seed for this one aswell. Get Maggie and die to your own bomb at cave Make sure to put the game to hard difficulty and use the following seed - CD2H NNRN* Its on your first door down then leftДў. What you will need to do to unlock the lost ДЇor this one, you can use a seed. If you are on PS Vita/PS4, after each step just upload your save to the server, and if you die just redownload it, and continue from the step you where on.ДЇor those that prefer it that way, I have added a video below showing the way to do it aswell. However, there is 1 way in which you can somewhat fool the system. If you die inbetween steps, you will have to redo the entire process again. You will need to do all steps in a row, without dying, unless needed for that step.

There are video's for it on youtube, but I've read alot of mixed comments about it not unlocking for alot of people, so here's my method. This is the way I used to unlock the lost (worked first try) and I would advice you to try the same. The Lost has zero health, meaning you hit once its game over. The lost is, as the trophy description says the final secret of the game. After just unlocking The Lost myself, I figured I would make a guide for it, seeing as there is next to no info about him.
