In BioShock Infinite, there was a lot of energy invested into developing your relationship with Elizabeth. By the end of the game, you knew everything about her, her abilities, her hopes and dreams. But the truth is she knew almost nothing about you, the gamer playing Booker. In Judas, the Big 3 observe you as you play, and they have feelings not only about how you approach combat, hacking, and crafting, but most importantly your interactions with the other two characters.
When you play BioShock or BioShock Infinite, the villain is always going to be the villain. Fontaine, Comstock — they’re always going to be the bad guys. In Judas, your actions will attract members of the Big 3 to you as friends. But ignore one of them enough, and they become the VILLAIN. From there, they will get access to a new suite of powers to subvert your actions and goals.
