Disgaea 1 Complete is a revamped version of Disgaea: Hour of Darkness, incorporating additional content from Afternoon of Darkness and Disgaea PC. Released on October 9, 2018, for Nintendo Switch and PlayStation 4, this game brings a fresh experience to fans of the series. It introduces updated elements such as new high-resolution sprites reminiscent of Disgaea 5 and character art images in the Disgaea 5 art style.

The game also features a rework of character classes, replacing some generic humanoid and monster classes from Disgaea: Hour of Darkness with classes from later games in the series. With these enhancements, Disgaea 1 Complete offers both nostalgia for long-time players and a revitalized look for new adventurers stepping into the Netherworld.
