Can I share my DLC?
For free to play games, DLC cannot be shared since all Steam users "own" the game. Any user may purchase, trade, earn, or otherwise acquire in-game content while playing a game, but in-game items cannot be shared between accounts. These items remain the property of the account that purchased or acquired them.
How does DLC work in DBD?
DLCs add new Characters to Dead by Daylight and are often, but not always, accompanied by the Developers adding a new Map, themed after the DLC content, to the Base Game. These DLCs include: 31 Chapters, released every 3 months, add a new Killer AND a new Survivor.
