Disgaea 4 Complete+

Combat is carried out in a turn-based strategy fashion. Allies can be deployed into combat, each with their own special skills and "Evilities", additional abilities that are applied to every character. Enemies and allies may be picked up and thrown, just like previous Disgaea games. However, Disgaea 4 adds a new feature to its grabbing system, allowing any friendly character on the field to pick up another adjacent friendly character, and continuously pick up allies, in a tower fashion.

When in the tower formation, the movement ranges of the stacked characters increase. The bottom character of the tower can also throw the tower ahead of him/her to further increase movement distance. Special abilities may be activated while in tower formation, such as specific team attacks and the ability to obtain items normally unreachable due to a wall.

The game takes place in a Netherworld, common in Disgaea titles, and similar to Disgaea 3: Absence of Justice, focuses itself on a specific theme. Nippon Ichi, apparently feeling that it had exhausted all the game systems a school setting can provide, made the story one of a more political nature. While aspects of Netherworld politics existed in previous games, it is the central focus of the story and the gameplay in Disgaea 4.

Disgaea 4 follows Valvatorez, a vampire who was once feared as a tyrant until he promised a woman 400 years ago that he would not drink blood until he could instill fear in her, and she died before he could do so. He now has a menial job in Hades, where the souls of dead humans are sent to be transformed into Prinnies, alongside his loyal servant, Fenrich. When the Corrupternment orders the mass extermination of all Prinnies, Valvatorez and Fenrich put a stop to it and, disgusted by the government's actions, Valvatorez plots a rebellion.

The game has received generally favorable reviews, with an aggregated score of 80/100 on Metacritic. 5 saying "Fans of the series will find exactly what they expect here -- and non-fans will find exactly what they fear ... This is probably the best Disgaea since the 2003 original'. GameZone gave it a score of 9/10, stating "Overall, Disgaea 4 is a blast, and easily cements Nippon Ichi’s legacy as the kings of the strategy RPG genre.

" Famitsu awarded the game a total of 33/40, composed of a 9/8/8/8 score. The game sold 79,425 copies in its first week in Japan, putting it at fourth place.
