Developed as a title for Mega Man's 20th anniversary, Mega Man ZX Advent is a fast-paced action game that follows two heroes, Grey and Ash, on two separate but intertwining adventures as they search for answers amidst a chaotic war between humans and robots. They 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.
