The developer of Riviera, Yggdra Union and Knights in the Nightmare has a new DS game on the way. Sting, who's other titles include Baroque on Wii and Treasure Hunter G on SNES, is recreating a mobile phone spin-off from Yggdra Union to the Nintendo DS in the form of Yggdra Unison: Holy Sword War Tales. The game is due for release in Japan this December and is to be published by Atlus.
Not long after the announcement of the PSP remake of Yggdra Union, a larger mobile phone game effort was released called Yggdra Unison: Beat Out Our Obstacle. The game features a territory conquering system similar to that found in games like Emperor: Battle for Dune. There are eleven armies vying for 36 territories in the game, each taking a turn in which they can attack a neighboring territory, potentially conquering it and thus increasing their presence on the continent. In battle, characters move around in real time, and when two opposing enemies encounter each other, a skirmish more similar to those found in Fire Emblem is initiated, with the units attacking each other. With proper timing a Unison attack can be activated, in which all allies within a circular range of the skirmish will also engage. The cards featured in the original Yggdra Union are also activated within skirmishes.
According to Famitsu magazine, Princess Yggdra will battle foes in a real-time simulation forum, with players commanding units on a field map and triggering dual battles, in which they can then line up a group of allies to chain together unison attacks with deadly force!.
