Here's the latest trailer for Halo 4's co-op campaign, Spartan Ops. We've reached episode 10 now (it's the last of the Season 1), but we've also included the trailer for episode 9, because we're nice like that.
There's an update due on Monday, and it'll include Team Throwdown, what 343 are calling their "premiere competitive playlist." At launch it will include Team Slayer, Capture the Flag, Extraction and King of the Hill.
