This game contains elements from the Mega Man X series and the Mega Man Zero series. The game introduces a new open-ended gameplay environment and the ability to select the protagonist's gender, a first in the series. The player's character, Vent or Aile, is on a 2-dimensional overlay map with sprites where he or she engages enemies to finish the mission. When Vent and Aile receive a Biometal, they are able to change form, gaining various abilities, such as the charge moves, or charging their weapon with an element of that Biometal; for example, Biometal H will charge the weapon with electricity. While in a special form, using the form-specific abilities use up weapon energy. When Vent and Aile receive the other half of the Biometal, they are able to perform a different special ability.
