The file size has been revealed for the PlayStation 4 version of Dark Souls 3 Ashes of Ariandel. When view directly on the PS4, the expansion for the popular action role-playing game is going to take up 1.6 GB of free space from the hard disk drive.
The DLC requires the main game, which you can purchase with this link from Amazon. Ashes of Ariandel is also a part of the season pass of Dark Souls 3, which is available with this page.
Once downloaded, the expansion can be accessed by warping to the Cleansing Church Bonfire at Cathedral of the Deep. Talking to the non-playable character in the area will eventually result in a cut scene that will transport you to the new area.
