We’ve heard before that solving puzzles in Shadow of the Tomb Raider will be more dangerous than in the previous games. Now, Game Director Daniel Chayer-Bisson said in no uncertain terms in an interview with EDGE magazine (July 2018, issue 320) that this will be the most difficult game in the history of the franchise.

This will be, I would say, the most difficult Tomb Raider of all the Tomb Raiders. That is important because this is a more experienced Lara. This is going to be bigger, it’s going to be harder, and that tomb shows the first ever puzzle you’ll solve and it’s very difficult.
