The gameplay involves selecting which of the three Valkyries - Hikaru, Max, or Millia - to play as, each with its own set of weapons and movement speeds. The Valkyries can change their forms: Fighter, Gerwalk, and Battroid, affecting their firepower and speed. Each weapon has strengths and weaknesses: the Fighter shoots straight and quickly, while the Gerwalk's projectile can go around or through obstacles; the Battroid deals more damage but fires less often. Players can upgrade these weapons by collecting power-up items from enemy ships.
In a nod to Galaga, players can capture some enemy ships to boost their firepower. If a Valkyrie is not shot for a few seconds, an electric field will appear, and touching friendly enemy ships will render them harmless.
