In Mega Man ZX Advent, the main characters discover the power of the mysterious "Biometal model A," which on its own has several attacks, but also has a special Megamerge ability which allows the character to transform into one of eight "Pseudoroid" bosses that each have a unique set of abilities. Once a boss is defeated, players can emulate their powers to find hidden routes, discover rare items and aid their battles against more powerful enemies. The title takes full advantage of the Nintendo DS features to enhance the action-packed gameplay and story line of the popular series.

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.
