Developer Infinity Ward decided before to involve the Call of Duty community in making one of the biggest decisions for Call of Duty 4: Modern Warfare ... the box art.
Their art department created five different box art concepts to choose from (Alpha, Bravo, Charlie, Delta, and Echo)
And now, after gathering all the feedback and tweaking the designs, Infinity Ward ended up with the final design people have chosen. The winning design is based off of the "Charlie" concept blended with a touch of "Echo" for good measure.

Call of Duty 4: Modern Warfare will introduce a variety of game play styles into the single player campaign completely new to the Call of Duty series. The game moves away from the standard three country-specific campaign style, and allows the plot to play through more like a film style plot with interlaced story lines from the perspective of the player as a member of the US 1st Force Recon and a member of the British 22nd SAS Regiment. There is also a variety of cameo-style missions where you play as various other soldiers such as an AC-130 Gunship gunner, or as one part of a two man sniper team behind enemy lines in a flashback style mission.
The series' move to modern warfare has also introduced a variety of new modern weapons and technology to be introduced to the Call of Duty franchise. Such showcased weapons and attachments include M203 grenade launchers, IR laser pointers for use in conjunction with night vision goggles, silenced MP5SD submachine guns, and the FGM-148 Javelin portable anti-tank guided missile among many others.
A Russian nationalist by the name of Zakhaev is set on returning his homeland to the Soviet times. Zakhaev knows the United States would never allow this to happen, thus he funds a coup in the Middle East, organized by his ally Al-Asad, to draw attention away from Russia. The two men and their seconds-in-command gain the nickname The Four Horsemen. However, the British and US governments have been monitoring Zakhaev's activities and discover his real intentions. The story is told from a perspective of a British 22nd SAS Regiment operative in Russia and American 1st Force Recon in the Middle East.
