We already know Rise of the Tomb Raider won't feature a completely separate multiplayer mode, but it will tie-in with its single-player.

Rise of the Tomb Raider’s Creative Director Noah Hughes explained everything regarding the matter, and how the introduction of the new Expedition Cards will allow you "to customize your experience in extra modes."

"We’ve taken a new approach to competing against your friends in Rise of the Tomb Raider with the introduction of Expedition Cards. In addition to offering the ability to customize your experience in extra modes, they let you craft missions and challenge your friends to reach the top of the leaderboards."

These Expedition Cards can be purchased by earned credits, or bought by real money, which means there will be micro-transactions in the game. There will be two types of cards, Foil Cards and Common Cards. Foil Cards will offer the "strongest or strangest variations," and can be used several times. On the other hand, Common Cards can be used only once, and you need to buy it again every time you want to use it.

"In Rise of the Tomb Raider, you’ll earn credits by completing challenges and exploring the world. These credits can be used to purchase Expedition Card packs. When used, Expedition Cards become modifiers in game modes outside of the single player campaign.  Some Cards are humorous, such as Big Head Mode, while others can increase the challenge or give you special advantages. Expedition Cards can also be purchased with real-world currency."

"There are two types of Expedition Cards: Foil and Common. A Foil Card will give Lara the strongest or strangest variations and can be used as many times as you wish. A Common Card is only used once, and you’ll need to earn more credits to buy it back."

"Expedition Cards offer hundreds of ways to customize your Rise of the Tomb Raider experience. You can also set up challenges for your friends to see if they can beat your scores with the same card setup. We’ll have about 300 cards available at launch, and more will be added in the weeks that follow."

Rise of the Tomb Raider releases first on Xbox One and Xbox 360 on November 10, then on PC and PS4 in 2016.
