Cowboy Bebop-meets-Master Chief action presented in the first episode of Halo Legends (seriously, that main character looked just like Spike Spiegel!), then you may want to check out the second episode of the Spartan-themed anime premiering today on Halo Waypoint. For 24 hours starting at 12:00AM PST (about eight hours ago), Xbox Live Silver and Gold members will be able to access "The Duel" through the "all-things-Halo" hub.
Microsoft also notes that this will be the last week for Xbox Live Silver members to explore Waypoint, and in turn, enjoy the weekly free episodes of Halo Legends. If you're wondering what time the show will be available for you and you don't live in North America, a full list of showtimes is available on Xbox.com.
