Following Call of Duty: Ghosts official reveal during Microsoft's Xbox One event, Infinity Ward announced that Raven Software and Neversoft supported the studio during Ghosts development.
"Now that our reveal is live, we wanted to give a special thanks to @RavenSoftware & @Neversoft for their support in developing #CODGhosts," the official Twitter account of Infinity Ward posted.
Raven Software previously worked on Call of Duty: Black Ops' and Call of Duty: Modern Warfare 3's downloadable content and user interfaces. Polygon reported in June last year that Neversoft was working content for a Call of Duty title when it announced that it was "ready to push the first-person action genre in support of Activision's Call of Duty franchise."

Call of Duty: Ghosts will launch on Nov. 5 for PlayStation 3, Xbox 360, Wii U and Windows PC. The game will hit Xbox One at an unannounced date and will receive all DLC before other platforms as timed exclusives.
