The grid-based battles of the cult-favorite Disgaea series continue in its second foray on PlayStation Portable. Gamers control a small squad of wizards, warriors, and ruffians, who fight together in turn-based combat against enemies and rivals, through magical, gothic-fantasy inspired settings. For fans of the series, Dark Hero Days moves the story forward through four deep chapters and introduces a new playable character. Developed at Nippon Ichi Software studios, the game retains the title's distinct style of and animé-influenced art and animation, as well as its quirky, character-driven sense of humor. It also retains recent gameplay additions and refinements, incorporating the "Magichange" ability combinations, the throw-and-receive system, and Item World level spheres introduced in Disgaea 3: Absence of Justice on the PlayStation 3. In all, the PSP adventure features more than 50 original battle stages, and an unlimited number of randomly generated battle maps. ~ T.J. Deci, All Game Guide
