The outlook is grim as the dark Netherworld has been taken over by evil rules who have no rightful claim to the throne! You, as the young prince Larharl, are the heir to the throne and will need to kick some serious evil-guy butt to solidify yourself to your rightful position as ruler of all things evil! To aid you on your way, you need to assemble a team from the 150+ character classes and monsters, find the coolest and shiniest of weapons, and learn to use some of the over 100 mind-blowing spells and special skills that are at your disposal.
Battle your way through your weapons to power them up, try to corrupt the dark assembly, or spend some time in the hospital. No matter what you do, it's time to start acting like the king!
Disgaea: Hour of Darkness was released for the PS2 in 2003.
A port for the PlayStation Portable named Disgaea Portable was released in Japan on November 30, 2006. It was later released in the United States on October 30, 2007 under the name Disgaea: Afternoon of Darkness.
Afternoon of Darkness features extras over the original, such as a 16:9 format to take advantage of the PSP's widescreen display. There is also a mode that focuses on Etna as the main character. In Etna Mode, Etna kills Laharl by accident while trying to wake him in the beginning of the game and thus becomes the main character. There are some extra boss battles such as Overlord Zetta from Makai Kingdom and Rozalin and Adell from Disgaea 2. There is, for the first time, a multiplayer mode available through Ad-hoc connections. This features multiple modes such as a "Defeat the Leader," "Capture the Flag," and the original "Battle." In the Multiplayer mode, each player also has access to "Geocubes" which give different effects to the battlefield. Other new additions include a music shop, which allows the player to listen to the game's various songs and even change the Item World theme, and a record keeper, which keeps track of various bits of information such as ally kills and obtained items.
In addition, Afternoon of Darkness includes a complete dual language option and the option to turn off battle animations. Most of the silent Japanese cut scenes now include voice acting. However, when set to English, the scenes that were originally silent in the PS2 release are still silent. To reflect Etna's recent voice actor change, her lines have been re-recorded to match Michelle Ruff's portrayal of Etna in Disgaea 2 and the anime.
