Completed with 100% of trophies earned. Primarily focused on a set of seven additional challenge tombs, the Challenge Tomb DLC pack provides more of where Shadow of the Tomb Raider most excels, with an impressive variety in the environments and types of puzzle approach. Well-integrated into the game, each tomb is accessible via a bespoke side quest sequence but also individually via the main menu - ideal for attempting the score attack and time trials.

I can see an argument that these could be bulking out the game a little too much beyond the core story, but if you take these as individual challenges I certainly wouldn't complain. As a minor note, the additional outfit and weapon that comes attached to each tomb felt somewhat unnecessary, and the weapons in particular just get lost in an already quite extensive list.
