Eidos Montréal shared plenty of details on the New Game Plus mode featured in Shadow of the Tomb Raider.

If you’re not familiar with it, New Game Plus is the ever-more-popular mode where gamers can begin from scratch the campaign without losing the powers/abilities and weapons/armor they have acquired in the previous playthrough. Shadow of the Tomb Raider will work in a similar fashion, too.
