call of duty modern warfare 2

According to Infinity Ward, Modern Warfare 2 would not carry the Call of Duty moniker despite being a sequel to Call of Duty 4: Modern Warfare. The box art says otherwise.

Call of Duty: World at War allowed players to progress through the campaign in four-player cooperative mode. You'll be going it alone in Modern Warfare 2's campaign, though.

You may have noticed that the phrase Call of Duty never appeared in the teaser trailer for Call of Duty 4: Modern Warfare's sequel. That was no accident.
