With Halo 4, 343 Industries hopes to keep players coming back to the game with the co-op Spartan Ops mode. It will tell an episodic story rolled out progressively, to keep players coming back. But depending on its success, 343 could keep it going with more "seasons" of episodes.
Franchise development director Frank O'Connor said during our preview showing that the Spartan Ops episodes are being built with more seasons in mind. In other words, if 343's data shows plenty of players trying Spartan Ops, and sticking with it through the whole season, we can probably expect more to come.
