Halo Legends (ヘーローレジェンズ Hērō rejenzu) is a 2010 German-American-Japanese adult animated military science fiction anthology film produced by 343 Industries.

343 creative director Frank O'Connor produced story outlines or finished scripts that the production houses animated in a variety of styles.

[5] On board the ship Forward Unto Dawn , the artificial intelligence Cortana and Master Chief are stranded after the events of Halo 3.

Cortana narrates past events: thousands of years ago, the Forerunners were a great civilization, but they came under attack by the parasitic Flood.

After trying other methods, they developed a weapon of last resort; an array of ringed megastructures called Halos that would destroy the Flood and their food supply—every sentient creature in the galaxy.

Humanity's exploration and colonization of other worlds coincides with the rise of the Covenant, a theocratic alliance of alien races that worship the Forerunners and reverse-engineer their technology.

A marine sergeant nicknamed Ghost and his demolition team are sent to destroy a prototype weapons facility to prevent it from falling into Covenant hands.

Not wanting a repeat of his last mission, in which his entire platoon was killed, Ghost commandeers the heavy armor suit and uses it to provide cover for his squad as they evacuate.

[11] The film's United States premiere was held at the AMC Metreon in San Francisco on February 10,[12] with the companion soundtrack released by Sumthing Distribution the day previous.

"[13] IGN US reviewers Cindy White and Christopher Monfette said that the short films "prove surprisingly accessible to sci-fi fans in general," and that the collection was "well worth" the time.

[14] Matt Miller of Game Informer said that Halo Legends would appeal to story-interested fans of the franchise, not those who cared about multiplayer gameplay.
