Seatown is a small map featured in Call of Duty: Modern Warfare 3. The map has many buildings and tight alleys that offer close-quarters combat, as well as a castle in the southwest. It has a marketplace in the center of the map that has many over-watch positions. Much of the combat takes place in the market and surrounding areas. There are not many vehicles on the map, but there several alternate routes and walls, offering for escape or cover. There is also a well at the bottom of the map.
The players start near the well. The Weapons armory is located under the building on the west side of the map, the Equipment armory is located on the east side, and the Air Support armory is located on the north side.
