Dark Souls is a dark fantasy action role-playing game series developed by FromSoftware and published by Bandai Namco Entertainment. It began with the release of Dark Souls (2011) and has seen two sequels, Dark Souls II (2014) and Dark Souls III (2016). The series was created by Hidetaka Miyazaki and has received critical acclaim, with its high level of difficulty being among its most discussed aspects, while the first Dark Souls is often cited as one of the greatest games of all time. By 2023, the series had shipped over 35 million copies outside of Japan. Other FromSoftware games, including Demon's Souls, Bloodborne, Sekiro: Shadows Die Twice, and Elden Ring, share several related concepts and led to the creation of the Soulslike subgenre.
