Mega Man ZX Advent[a] is a 2007 action-platform game developed by Inti Creates and published by Capcom for the Nintendo DS.

The game was first released in Japan on July 12, 2007; in North America on October 23, 2007; in Europe on February 29, 2008; and in Australia on March 5, 2008.

ZX Advent follows two new protagonists, Grey and Ashe, as they battle with various enemy "Mega Men", the infamous Model W, and their own destinies.

Advent features a very large cast of characters both new to the series and returning from the first ZX, including the two main protagonists, eight Mega Men, the Sage Trinity, and eight Pseudoroids.

A majority of the cast is playable by copying their forms with A-Trans, and thus, these characters are outlined in detail below in the corresponding sections.

Many of the elements from Mega Man ZX return, including the 2D world and several missions and collection side-quests, as well as much of the gameplay.

Beginner simplifies the gameplay by weakening enemy's defenses and attacks and disabling instant-defeat obstacles among other things.

Expert Mode also limits the gameplay for the player in being able to collect only one Sub-Tank, and removing all the Life-Up and Bio-Metal Upgrades.

Several special disks are also featured, including an image of the infamous North American box art for the original NES game.

Composer Ippo Yamada explains a Soundsketch as "when you listen carefully in a room that seems silent, you can hear all sorts of sounds like the hum of appliances, the tick of a clock and the environment outside the window.
