Not long after the announcement of the PSP remake of "Yggdra Union", a larger mobile phone game effort was released called . The game features a territory conquering system similar to that found in games like "". 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. A Nintendo DS port of this game was released in Japan in December 2009.
