The Fall of Reach, retold.
Halo may be getting a brand new game this year, but for fans of the universe and lore that Bungie and 343 Industries built up, there is more to look forward to- Halo: The Fall of Reach, the novel that described the Fall of the planet Reach (a story which partially figures in Halo: Reach) will be adapted to cartoon form, it was announced at Comic Con this year. We also got to see what this animated series would look like with this trailer for it, which you can see above.
Done right, this may actually be able to do more and better justice to the Halo lore than any other piece of Halo media yet- Halo has had several attempts at cross media properties before, including Halo: Forward Unto Dawn and Halo: Nightfall, but none were particularly well received. This looks good enough that I am a bit optimistic about it.
Stay tuned for more coverage.
