Rust

Rust is the smallest map on Modern Warfare 2, it's set in an Oil rig which is situated in the middle of desert. The main focal point of this map is the large tower structure in the middle of the map, it's on 3 levels starting from the desert to all tall platform, which is a perfect vantage point. The rest of the map is coated with various cover ranging from Trucks, rusted cars and portable cabins. To the south-west of the map is a small amount of cover in the form of a pylon, this is were some players will camp as it looks over most of the map. This map is the "sister" to Call of Duty's 4's "Shipment", but this map has more cover and is slightly larger.
Due to the apparent size of "Rust" the spawns can get over-lapped and the two opposing sides can in effect "spawn-camp" each other making this terribly annoying for the afflicted player.
