In October 2007, shortly after the release of Halo 3 , Halo developer Bungie split off from parent company Microsoft. Microsoft retained the intellectual property and rights to Halo , and Bungie continued developing Halo games until 2010. During this period of time Microsoft formed an internal division, 343 Industries, to manage the franchise and develop future games.  
Including contractors, 350 people worked on the game.  343 Industries contracted Certain Affinity , an independent video game development studio, to help with the development of Halo 4 ; they started work on the game in early 2011.  Certain Affinity has worked alongside Bungie and 343 Industries on producing multiplayer content for previous Halo titles.  The studio developed the Forge mode, co-developed War Games and created a number of maps and multiplayer modes for Halo 4.
