Akiba's Trip: Undead & Undressed

He becomes a hunter to defeat the synthisters who prey on regular humans. Along with a band of freedom fighters Nanashi gets to roam the streets of Akihabara with over 100 shops modeled after real-life ones. Fights are done with brawling beat 'em up gameplay against one or more opponents in a small environment. The protagonist can use multiple stances and perform duo attacks with allies, targeting different parts of his opponents. Attacks can be strung together to form combos and there are many types of weapons that can be upgraded.

Next to the fights, a large amount of time is spent exploring the environment and completing missions to earn money. There are also many NPCs to talk to. Conversations often have dialogue trees and the answers not only affect the fights with synthisters but also relationships with the male and female cast of characters who can join or leave the protagonist's party. The game contains many shops where items, weapons, clothing, and food can be bought and sold.
