The game is set in a world where no sin is forgotten. Players take on the role of Harkyn, a convicted criminal whose sins are visible on his face, in the form of runes. The world's rulers are working to banish all evil from humans; it is unclear what exactly this might mean for someone like Harkyn. When an army of long-defeated gods attacks the human realm, Harkyn is released from prison with a chance at redemption. Along with his mentor, Kaslo, the journey to stop the attacks leads to Rhogar, another dimension inhabited by demons. Players can form alliances as they progress, combat enemies of ever-increasing difficulty, and eventually travel to the heart of the demonic realm, in an effort to achieve forgiveness for the anti-hero, Harkyn.
Lords of the Fallen is an hack and slash action role-playing game and is often compared with video games like Darksiders and Dark Souls. Both Lords of the Fallen and Dark Souls have a realistic combat system, but Lords of the Fallen differentiates itself by not punishing the player for making mistakes. The game uses many save points to make sure the player doesn't lose too much progress.
