I installed New Game Plus from the PlayStation Store, though I am not sure what it does. I think it's a feature to get more out a playthrough after you have completed it, but I just don't understand what is the difference between a new save or a previous save with NG+.
- Do the items, levels and diagrams get kept?
- Am I able to get new contracts and missions?
- What will be of my choices?
- What happens if I just continue playing instead of starting a New Game Plus over it?
- Does my save get overwritten?
