Enter the Matrix is an action-adventure video game developed by Shiny Entertainment and published by Infogrames, released under the Atari brand name. It was the first game based on The Matrix series of films. Its story is concurrent with that of The Matrix Reloaded, and features over an hour of original footage, directed by The Wachowskis and starring the cast of the film trilogy, produced for the game. It sold one million copies in its first eighteen days of release, 2.5 million over the first six weeks, and ultimately 5 million copies. The success led to the game being re-released for multiple consoles' budget brands, with the PC version getting a DVD-ROM version.
