Enter the Matrix is a 2003 action-adventure video game developed by Shiny Entertainment and published by Infogrames under the Atari brand name. The first game based on The Matrix film series, its story is concurrent with that of the film The Matrix Reloaded and features over an hour of original footage, written and directed by the Wachowskis and starring the cast of the films, produced for the game.

Released in May 2003, the same month as The Matrix Reloaded, Enter the Matrix was simultaneously produced with The Matrix Reloaded and The Matrix Revolutions. While it received mixed reviews from critics, the game sold 5 million copies as of May 2004.

Enter the Matrix gives players control of two of the supporting characters from Reloaded and Revolutions, Ghost (Anthony Wong) and Niobe (Jada Pinkett Smith), members of the same group of rebels as Morpheus, Trinity, and Neo, the protagonists of the series. Niobe is the Captain of the Logos, the fastest ship in the rebel fleet. Ghost is the ship’s first mate, weapons guru, and a deep-thinking, philosophical assassin. The game takes place at roughly the same time as the events in Reloaded.
