Enter the Matrix gives players control of two of the minor characters in that film, Ghost and Niobe, members of the same group of rebels as Morpheus, Trinity, and Neo. Niobe is the Captain of the Logos, the fastest ship in the rebel fleet. Ghost is the ship's first mate and weapons guru, and is a deep-thinking, philosophical assassin. The game takes place at roughly the same time as the events in The Matrix Reloaded; a character may walk out of a scene in the film, only to walk into a scene in the game. Like the films, the game features martial arts, firefights, driving, and bullet-time. It also includes a "hacking system" that simulates the ability to hack into the Matrix by way of a simplified mimicry of DOS, exploring and unlocking secrets, weapons, maps, and skills.
