Dark Souls is a 2011 action role-playing game developed by FromSoftware and published by Namco Bandai Games. A spiritual successor to FromSoftware's Demon's Souls, the game is the first in the Dark Souls series. The game takes place in the kingdom of Lordran, where players assume the role of a cursed undead character who begins a pilgrimage to discover the fate of their kind. A port for Windows featuring additional content, known as the Prepare to Die Edition, was released in August 2012. It was also released for consoles under the subtitle Artorias of the Abyss in October 2012.

Dark Souls has been cited as one of the greatest video games ever made. Critics praised the depth of its combat, intricate level design, and use of flavor text. However, the game's difficulty received mixed reviews, with some criticizing it for being too unforgiving. The original Windows version of the game was less well-received, with criticism directed at several technical issues. By April 2013, the game had sold over two million copies worldwide. Its success led to the development of two sequels—Dark Souls II (2014) and Dark Souls III (2016)—while a remastered version was released in 2018.
