Yggdra Union: We'll Never Fight Alone is a tactical role-playing game for the Game Boy Advance, developed by Sting and published in North America by Atlus. The game has a similar flair to another Sting-developed game, Riviera: The Promised Land. The game is a Tactical RPG in the vein of the Fire Emblem games, with an overhead view of a 2D map, managing miniature versions of your units. However, aside from the map view, it is quite different. A card system dictating your movement and potential skills plays into both enemy and ally turns, as well as the "Union" formation system, in which massive battles can take place between several platoons.
There are also some real time elements included during actual battle sequences, such as being able to control how your units attack the enemy.
