You mean this?
one is to have s3x with Mal0 3 times in a row, second is keep demand answers from Zellen a then is red screen = death, third one is do what Zellen asks then keep blocking or not the data i think it doesnt matter i choose to allow to Zellen receive the data then go talk with Zellen then help her and then you have 2 options to let Mal0 go or refuse to give up Mal0, if you choose to let go then you have True Ending if you choose not to let go you have Good Ending, but the first one im not sure it is the one i dont remember now
