The Rise of the Tomb Raider season pass includes "a range of content that will extend your single-player campaign, and also allow you to compete with friends," according to a listing on the game's Xbox.com product page.
The season pass description states it will grant players access to "three major releases" that "challenge you to survive the extreme conditions of Endurance Mode, explore a new tomb that houses an ancient terror in Baba Yaga: The Temple of the Witch, and combat waves of infected predators in Cold Darkness Awakened."
It will also deliver "a steady stream of outfits, weapons, and Expedition Cards beginning on Day One and continuing over four months." This will keep players "customising, expanding, and challenging friends to new adventures."
Expedition Cards are sold in packs of five and bestow a "distinct advantage" on Lara. These can be used in all extra gameplay modes. Currently, Xbox.com lists Gold, Silver, Challenge, Advantage and Wild Packs, with each one "guaranteed to contain at least one rare card."
Neither Square Enix nor Microsoft have officially announced or detailed the season pass. Its existence was leaked by Amazon, which listed the pass for $30.
Although details on Rise of the Tomb Raider's multiplayer mode have not yet been divulged, a recent report revealed will not have a traditional multiplayer mode like its predecessor did.
The Rise of the Tomb Raider release date has been confirmed as November 10 for Xbox One and Xbox 360, with PC and PlayStation 4 versions landing in 2016. For more on the game, check out GameSpot's recent preview, "Like Father, Like Daughter."
