The gameplay won't change. Its a dlc, not the sequal. Possibility of new vigors or weapons. Doubt you will play as songbird because that would completely change gameplay. You won't play as the lutece twins because they don't exist in a single universe. They can go to wherever they want, whenever they want. That would make gameplay as them confusing, strange, or just plain weird. Won't be set anywhere but columbia. I feel this is rather obvious. Setting it somewhere else would require a complete artistic redesign. Not outruling the possibility of playing as/travelling with a secondary character-that would be a nice change(not that i have a problem with booker or elizabeth, they are both well written and deep). Enemies with vigors sounds reasonable. Also:
