Phantom Dust is a 2004 real-time strategy action video game developed and published by Microsoft Game Studios for the Xbox console. The game was released in Japan on September 23, 2004 and in North America on March 15, 2005, licensed for release in North America by Majesco Entertainment.

Phantom Dust is an action/strategy game with elements of digital collectible card games. Taking place in a post-apocalyptic Earth, the unnamed player-character must interact with the few human outposts that remain, all who have suffered a form of amnesia, to understand what has happened to the planet. Throughout the game, the player takes missions to collect artifacts of the past to help piece the past together, and where they face off in battles with other non-player characters. The player collects numerous skills by completing missions, which are used to assemble customized "arsenals" that they take into battle arenas against enemies. The game also included a multiplayer mode, allowing players to compete against each other using their arsenals.
