The battle is between Task Force 141 and Afghan OpFor. It is set in an oil yard in the middle of the desert. It is considerably larger than Shipment from Call of Duty 4. Featuring a tall tower surrounded by open space with some cover such as containers and some pipes. The central tower has a ladder and two connecting pipes to reach the top, allowing players to see the area below. There is another elevated area in the corner by accessing the round pipeline. Behind this building is a small tunnel, one of the few areas that provide good cover from air attacks. Furthermore, the area around the tower has two hidden "tunnels", one by the ladder, and the other on the other side. They are very dark and small, and can be used by stealthy players to ambush enemies.
Rust is the 'spiritual successor' to Call of Duty 4: Modern Warfare's Shipment. While the majority of Rust's layout is different, the two maps are both very small maps. This is also one of the more multiplayer-flexible maps. Only close range weapons will work here.
Due to the small size of the map, players will spawn within close proximity to each other. Occasionally, players will spawn directly in someone else's line of sight, resulting in very quick kills. There are very few viable camping spots as most locations are exposed or easily accessible. It is very rare now to have a match here and hard to build streaks.
This map is generally unpopular due to the amount of "spawn kills" and grenade spamming as well as a large amount of Grenade Launchers and Thumpers used, skilled and experienced players can often counter these methods. Although it is easy to get vast amounts of kills on this map it is still generally skipped for larger maps.
Sometimes the player can run into a team of pure "stabbers" which can be daunting to others as well as spammers.
While the player is being loaded onto the helicopter at the ending of campaign level "Endgame", Rust can be seen in the background.
