Port Valdez is a popular map in the game, set in Alaska, along an oil pipeline that the Russians are seeking to seize control of. Port Valdez was the map made available in the Xbox 360 beta of the game, which was released before the official title. The map has very open sightlines, but there are commonly close-quarters fights, where shotguns and SMGs reign supreme. Many of the M-COM stations are situated inside buildings, meaning that two different playstyles are often needed to secure or destroy the point. You need to be able to make it to the station, and then you need to be able to hold it down in an area where more than likely, your rifle of choice will not be as potent as it needs to be. Furthermore, when enhanced with Frostbite 2.0, complete destruction of the map can become a reality - will you enter the building to destroy the M-COM or just flatten it with the T-90? The spawning point for the Russian team is unique in this map, as they parachute from a large aircraft which flies over their spawn. This happens only at the first set of M-COM stations. Occasionally combat on this map can come down to vehicular warfare, as there are a decent amount of vehicles available. When the American defenders are pushed back to their third base, they can grab an Apache gunship, which potentially could turn the tide on the Russkies. However, this may not always be the case, as the Russian base contains a BMD-3 AA, which is a gunship's worst nightmare. Of course, there is also the risk of someone sneaking over and stealing the gunship whenever it respawns. Vehicles available on this map include a Vodnik, T-90, Apache, Black Hawk, BMD-3, and ATV. Some of these vehicles only appear at selected bases, but they can always be difference makers.
Many players on the Attacking team choose to snipe at the first base, as there is a large rock directly ahead of the spawn which provides a good vantage point across the first base. However, the Defenders spawn in a building that is currently under construction, and is therefore able to provide many areas to snipe from - not to mention the fact the rock can be seen from virtually anywhere at the Defenders' end of the map. Sniping effectively may provide your team with a temporary boost, but there will always be another marksman who will pose a significant threat to you. Point A at Base One is a common place for the T-90 to be taken to, as it is a standard house, and will not stand up to the power of the T-90's tank shell for very long. As such, Point A is one of the more difficult areas to defend, unless the Defenders have an Engineer who is handy with his launcher, or a C4 wielding teammate. For the Attackers, they can use the two-floored building directly beside Point A to suppress the enemies, as there is a mounted machine gun at the top of the stairs which gives a good view of the construction site at which they spawn. Ultimately, most battles end at either Base Three or Four. Which team it ends with varies, but the Apache and Black Hawk can really aid the Defenders if the pilot and gunner are both competent in their roles.

Laguna Presa is one of the best looking maps as the vibrant and sharp colours of the jungle really jump out at you. It's covered in trees, long grass and a variety of other types of foliage which are designed to make the map feel tight nit. Sniping is much harder on this map as there are only limited places where snipers can place themselves to get a high vantage point over enemy spawns or capture points. The majority of the fighting will be CQB or long range open warfare, as there can be some areas which are very open and have the potential for conflict to erupt, testing the players skill in a situation which puts them under a lot of pressure. There are limited numbers of vehicles and the vehicles present are designed for either travelling from point A to point B or to take out infantry, there won't be many opportunities for full-on vehicular warfare.

Arica Harbor is another desert map, set in Chile, the main portion of the map is based around an abandoned construction site and most of the combat takes place either in or just outside the small cluster of buildings in the center of the map. There are minimal vehicles at one end the map but at the other hand there are more than 6 vehicles to us. The majority of the fighting will be CQB as the buildings are relatively close together. There are several high-rise buildings for snipers to inhabit, one of which has a view over the most popular area of the map and the other one is located closer to the main bunch of buidlings. Once players move on from the main cluster of buildings, they come to a long bridge, forcing players in to a more open type of combat. As you go further on, more small clustered buildings appear and then finally it gets a bit more open with random scattered crates and small cliffs for sniping. Overall, the map is a very good one with a decent amount of variety and has a good balance between CQB combat and long-range fighting.

Valparaiso Village is again one of the smaller maps, set deep in the jungles of Chile. The main portion of the combat is fought in and out of the jungles and a few small buildings. The first portion of the map is definitely more focused on CQB combat rather than long range. There are lots of trees, rocks and other natural obstacles put there for players to seek coverage from incoming fire. The second portion of the match is a mix between CQB and long-range, there is a massive lighthouse where snipers can stand and have a look over the whole map making it easy for them to pick enemies off. Down below, on the other hand is littered with shacks made of corrugated iron where enemies must battle out in close quarters. The third portion of the map, is a mix between CQB and mid-range combat. Again, a good map for all classes.
