The Spartan Ops feature in Halo is 343’s way of extending the longevity of the game while also giving the players new story elements and ways to play with their friends. Each week a new mission will be released for Halo that brings a whole new story to the Halo universe. While some may be stand alone missions, other could be story arcs that take months to complete. Not everything is known about this game mode yet, but i am very excited to see what is revealed later by 343.
