The original Call of Duty: Modern Warfare 3 is required for installation

Collection 4

The final, fourth collection of additional materials includes five new maps for the multiplayer game. Gulch will take you to an abandoned mining town, lost in the mountains, where you can hide from enemy fire in old tunnels and behind the wreckage of equipment. On the Boardwalk map, you will find the Jersey shore and furious shootouts on the beach under the hot midday sun. Off shore and Decommission will allow you to open hostilities at sea, fighting for an oil-producing platform and abandoned skeletons of ocean liners. In addition, you can also take part in battles in the city among the ruins of the French quarter of New Orleans on the Parish map.
