The latest Tomb Raider is quite unlike its predecessors in the series, and borrows some of the best features from games like Assassin's Creed, Arkham City and Uncharted. Namely, the game has secret areas that, once explored, give Lara Croft extra experience points, salvage and secret treasure maps.
Each of these hidden locations comes in the form of a tomb—hence the game's name, Tomb Raider—and contains a puzzle for you to solve. Finding these locations can be a challenge in itself, hence the video below by PowerPyx, who's discovered all of the locations and helpfully recorded them for your viewing pleasure.
It goes without saying that conquering these tombs will provide Lara Croft with the experience and salvage she needs to brave the game's more difficult challenges.
