 As a highly popular video game series with a large and active fan base , the Halo trilogy has given rise to an array of video productions in an emerging entertainment medium , machinima . Virtually all machinima footage based around the Halo games is taken from the multiplayer modes of the main trilogy games . Most productions are set outside Halo canon , while others are based on fan fiction closely relating to the official story . Halo 3 includes a saved film function that allows camera angles not possible in previous games , and other features that simplify production . The game has become one of the most popular tools for generating machinima , and Microsoft updated its user license agreement to allow noncommercial distribution of such films .
