Shadow of the Tomb Raider released last year to mixed reviews, but it received pretty good support either way. The Path Home, the seventh and final announced DLC, expands on what happens after the main story.
The Path Home will have you searching for missing allies and take you to a new challenge tomb where you will discover another ancient secret.
Something that might make certain people unhappy is that The Path Home is a Season Pass exclusive. This means you won't be able to purchase it separately like the previous six. It shouldn’t be too much of a problem if you didn’t get the season pass since it goes on sale regularly.
