Dark Souls: Daughters of Ash is the original Dark Souls (2011), re-imagined and massively expanded. It’s my vision of what Dark Souls might have been if FromSoftware had been given an additional six months to develop content for the game.
Put another way: this is an enormous fan-made overhaul of Dark Souls: Prepare to Die Edition on PC. (It will be released for Dark Souls: Remastered later in 2019.)
