Halo 4

The Fight is Finished, The War isn't.

Halo 4 is an Xbox 360 exclusive developed by Bungie and published by Microsoft. It runs on a highly modified version of the proprietary graphics engine used in the development of Halo 3.

Summary
Halo 4 takes place 2 years after Halo 3 concluded, in the year 2555. The game begins after angry Covenant Remnants attack a UNSC orbital platform, known as Vatican. The UNSC forces, beaten and still recovering from the war, send a distress signal to the Elite homeworld Sangheilios, where The Elders pick it up. They then go to The Arbiter, and several other fleets underneath his command, and send him and his followers to go defend Humanity, and end The Covenant once and for all. The Arbiter and his followers, The Old Covenant, then arrive at Vatican orbiting Earth, and must take back the station.

The New Covenant
The New Covenant, or Covenant Remnant, consist of a Hierarchy reformed by The Brutes, along with their slave races, The Drones, Jackals, Brutes, and Hunters. The current De Facto Leader of The Covenant is a single Brute Army Commander known as Icarus. Many of even his own followers believe he is letting his power get to his head, with pratically infinite control over The Military and Council.
