Assassin’s Creed Valhalla’s second expansion, The Siege of Paris, was further detailed during Ubisoft’s E3 2021 Forward livestream on June 12. It takes players to France a few years after the main game’s events.
During the livestream, Ubisoft revealed the expansion will see the return of black box-style missions. First introduced in Assassin’s Creed Unity, these missions task players with accomplishing a specific goal (like assassinating a target) but then let go of the player’s hand, allowing them to figure out how to accomplish the goal on their own.
These types of missions were also in Assassin’s Creed Syndicate. However, they were dropped in Assassin’s Creed Origins and have not returned since.
