The gameplay plays fairly similar to Lord of Arcana, with most of its combat mechanics bears similar to God Eater, although it usually focuses on combos and techniques. Players must explore the mission map, battling Gaist along the way. At the end of the map, a larger Gaist will appear as the boss, which requires defeating it to complete a mission.

Players can make use of various attacks, as well as using "Gaist Arts" and "Form Changes". When defeating the Gaist down, a special "Crash Chance" appear, in which the player must destroy Gaist's core (which was surrounded with Gaimetal) within a given period of time, rewarding them with a new Gaist Gear once completed.

The three things about this genre is to "equip, transform, and collect". To customize the right character with the correct Gaist Gear from the defeated Gaist bosses, and collect them all.
