Multiplayer Challenges

 are found in the Journal section of the Multiplayer in-game start menu. They are began by the player doing certain tasks, just like how you start the Single Player Challenges. Most, if not all, Multiplayer challenges are made much easier if the player can do them with a friend. The more people helping the player, the easier the challenges can get (some challenges are only able do be done by the player alone).

There are many more Multiplayer challenges than there are Single Player challenges, but all the challenges in Single Player are also in Multiplayer.
