For the first ending I believe there is another way to. I was playing along and a women told me where the Last Judgement Gang is and I didn't even need the subways.
I managed to get the ending of the Church of the Chosen Ones. Basicly, you have to let them manage the whole community. You will be given lots of choices during the game, concerning the Church.
I can't explain exactly WHY and HOW this ending triggers, but I'll write every "otential switches" I did , it might help you reproduce this success.
Good luck. But if you just can't reproduce it, all the endings are on youtube. Even tho they don't have the best quality.
The ending will trigger when the suicide rituals will have reduced your population to the number of THREE. As soon as you click on "End Day", the Church of the Chosen Ones will throw you (well, your character) over the fence, and you will die.
Note that with this ending, you cannot continue playing.
i did everything to get the chosen ones but it doesn't work and i died with the ending 6 the whole community just committed suicide in the church so all my 90 survivors are dead including mine too
