The characters and setting of the films are further explored in other media set in the same fictional universe, including animation, comics, and video games. The comic "Bits and Pieces of Information" and "The Animatrix" short film "The Second Renaissance" act as prequels to the films, explaining how the franchise's setting came to be. The video game "Enter the Matrix" connects the story of the "Animatrix" short "Final Flight of the Osiris" with the events of "Reloaded", while the online video game "The Matrix Online" was a direct sequel to "Revolutions". These were typically written, commissioned, or approved by the Wachowskis.
