Halo 4 comes with three capacious modes: Campaign, in which Master Chief faces a new Forerunner threat; War Games, a mixture of competitive multiplayer modes; and Spartan Ops, an episodic and story-driven series of four-player cooperative missions.

We have new screens from all three modes right below. Be sure to check out Chief's new opponents, the Prometheans - not to be confused with the Protheans from Mass Effect - and "Solace," a vibrant new battleground for competitive matches like Capture the Flag (yes, that guy above is shooting with flag in hand) and Halo 4's frantic spin on territory tussles, Dominion.
