If you're looking for a Sci-Fi Romance with a Halo skin on it, this is the show for you. If you want something that's even remotely close to Halo, go watch Red v Blue for the millionth time. This show is not meant for Halo fans. It's meant for people that have never played a minute of any Halo game.
It's set in an alternate universe so almost none of the Halo lore is followed.
