Disgaea 4 drops September 6

A return to the Netherworld is nigh for many a strategy role-playing game fan, as Nippon Ichi Software America today updated release info for a number of its upcoming titles, including giving its PlayStation 3-exclusive Disgaea 4: A Promise Unforgotten a September 6 launch date.

Disgaea 4 will incorporate a graphical overhaul over the previous flagship installment in NIS's quirky turn-based tactics role-playing series. And while the studio has also revamped the battle systems, it will retain many of the series' most familiar aspects. Characters like "Dark Hero" Axel and the penguin-like servants Prinnies will be returning, as will many familiar character and enemy types, all rerendered to take advantage of the new engine.

Later in the month, NIS America will launch another PS3 effort, the alchemy-focused RPG Atelier Totori: The Adventurer of Arland. Developed by Gust and set for a September 27 release, Atelier Totori is the sequel to last year's Atelier Rorona and focuses on the pupil of that game's protagonist.

Finally, NIS America confirmed that its downloadable PSP sequel Cladun x2 is set for North American release by the end of August. A follow-up to last year's retro-styled dungeon-crawling adventure, Cladun x2 puts more of a focus on customization, with players able to incorporate new classes into their parties and customize weapons, armor, background music, and even characters' facial expressions.
