When a new console arrives on the scene, developers often decide to choose the best titles from previous consoles to port to the new system, usually including all previously released DLC as an added incentive. This is certainly the case with Nippon Ichi Software, who have decided to port Disgaea 5: Alliance of Vengeance to the Nintendo Switch, under the new moniker of Disgaea 5 Complete.

After Void Dark, a newly crowned demon emperor, begins to destroy several of the Netherworlds with his powerful army known as The Lost, a demon named Killia teams with up with a sheltered Overlord by the name of Seraphina to rise up against Void Dark, and take revenge on the atrocities he has caused. Along their journey, they will recruit other Overlords and supernatural creatures that are sympathetic to their cause of revenge. Although the story sounds quite macabre, it is all very tongue in cheek, and the comedic situations that take place are indicative of a typical Japanese role playing game in the best possible way.

The basic goal of Disgaea 5 is to lead your squad of various demonic beings such as succubae, vampires, werewolves and former criminal penguin-like creatures known as Prinnies into battle, and defeat the foes that inhabit each stage. Like its predecessors, Disgaea 5 uses a turn based RPG fighting system, and requires you to use the numerous grid spaces effectively to obtain the best ranking at the end of each stage. When you are not facing the hordes of monsters in each stage, you will return to a hub world, which contains your standard item and weapon shops, a hospital area and a portal that takes you to the level select screen.
