On Main Ops 16, the player can get onto the roof of a miner's shack and trigger a special button prompt that, when pressed, has the player jump with their arms spread into a box full fo straw, accompanied by the sound of an eagle's cry. Once the player has completed the Leap of Faith, Kazuhira Miller explains the history of the "Assassin's Straw Box," stating it was used by an order of assassins in the time of the crusades. This is a reference to Assassin's Creed and the Leap of Faith the assassins do. The box is then unlocked for use in future missions. The box even allows the player to knock out guards while hiding in it, similar to how Ezio could assassinate guards from a bundle of straw.
