The first season of Halo 4's Spartan Ops is pressing onward. The third episode is due next week, with five new chapters coming on Monday, November 19 at 3 AM PT. 343 Industries has released a new trailer for the upcoming episode.

After recovering the artifact in episode two, the UNSC's attention turns to Dr. Catherine Halsey in this upcoming episode. The controversial doctor spearheaded the Spartan program, leading some to classify her as a war criminal. You know, taking children and all. But she's the one in charge of unlocking the secrets of the artifact, and the Spartans are tasked with finding more intel on it while she works. Finding more intel, in this case, almost certainly means killing more aliens.
