Halo 4 introduces "Spartan Ops," a separate adventure that follows the Majestic Squad aboard the UNSC Infinity in weekly, episodic releases accompanied by new missions. It represents one of the extra game modes available and can be played solo or cooperatively as multiplayer.
"Spartan Ops" replaces FireFight mode and allows up to four people to play. Alternatively, the competitive multiplayer mode, called "War Games," unfolds on the combat deck of the Infinity starship.
Halo 4 is expected to release on November 6.
Check out gameplay from "Spartan Ops" below, or view the introduction to both modes in the video above.
