Halo 4 is going to be one of this year's biggest games, and UK newspaper The Guardian managed to get an interview with the game's development director, Frank O'Connor, ahead of their E3 presentation with Microsoft.
Speaking to The Guardian's Keith Stuart, O'Connor said that the Spartan Ops mode they have planned for Halo 4's multiplayer "could run for years".
Spartan Ops is Halo 4's online episodic campaign which is set to be delivered in chapters in the weeks, and months, after the game's release. More than just missions, it's said to be accompanied by in-game cinematic sequences—like a regular campaign.
In addition to Spartan Ops, Halo 4's competitive multiplayer is making a return under the moniker of War Games, in which players can go head to head in a variety of competitive modes and customize their personal loadouts with a new system of enhancements called "Specializations."
The UNSC Infinity, which plays a major role in Spartan Ops and War Games is said to have a significant role in Halo 4's singleplayer campaign.
"Once you've completed the campaign and move on to other aspects of the game, then you'll start to find that the Infinity and the characters who live and work about it, are all deeply interconnected via the story that happens after the Infinity leaves the campaign story in Halo 4," said O'Connor.
