Baten Kaitos Origins is set 20 years before the original Baten Kaitos game. It describes how the evil Emperor Geldoblame came to power and fills in numerous facts about the heroes from the first title. In addition, players will discover the origins of the world and why the Lost Ocean has returned. The hero, a blue-haired young man named Sagi, was dispatched to assassinate the Emperor but discovered that the job had already been done for him. He’s on the run with two pals, a robot named Guillo and a young woman named Milly, after being blamed for the death. The player’s party will initially move linearly, traveling from one region to the next along a predetermined path. After a few hours of play, players will obtain a ship that allows them to visit areas in the order of their choice, allowing them to pursue extra side quests or rush through the primary mission as they see fit.
In contrast to traditional RPGs, where characters gain levels in areas such as strength and agility, the majority of leveling-up occurs through the acquisition of better Magnus cards. In Baten Kaitos Origins, there are over 600 Magnus cards, some of which have ry properties. Cards can be obtained in various methods, including trading, buying, receiving as spoils of battle, or making them themselves.
