We are considering adding additional DLCs at a later date, depending on the community's feedback.
Two DLCs have already been released though!
The Mythical Monsters DLC was exclusive to those who preordered Blood Rage: Digital Edition, and the Mystics of Midgard DLC got released the 17/09/2020 and was offered to all the players who owned or had purchased the game before the 21/09/2020.
After this date, the DLC will be available for purchase on Steam!
