Similar in concept to The Animatrix or Batman: Gotham Knight, each short will explore "different times, themes and characters" in the universe, with each sporting a distinct visual style. Microsoft Game Studios will be producing the series through its just-revealed 343 Industries division, which is dedicated entirely to the successful Halo franchise.

Microsoft also announced a Xbox Live "destination" called "Halo Waypoint," said to be a new information hub that will provide fans with related news, activities, behind-the-scenes videos, screenshots, podcasts, and so forth along with "a career system and player rankings tied to both in-game and out-of-game accomplishments related to Halo."

"A preview of select Halo Legends" will first be available through Halo Waypoint this fall, before Warner Bros. brings the release to stores at an as-yet-unknown date.

The Los Angeles Times was able to get some details on the various shorts:

Studio4 C's project, tentatively called "Origins," is a two-parter that's about 30 minutes long in total and tells the entire 100,000 year history of the Halo universe. Another, from Toei, is the only one outside of the official canon and pokes fun at some of the game's characters.
