Cargo takes place on the docks of London. The setting itself is a direct reference to the ship of Call of Duty 4: Modern Warfare mission, Crew Expendable. Being a fairly symmetrical map, it can be thought of as a very small, three lane map with most of the action taking place at the center of the map. Although it is relatively large for a Gunfight map, it feels small due to the tight arrangement of shipping containers.
At the sides of the map are sidewalks which offer a great view over the map at the cost of being exposed to the enemy. Moreover, players may choose to climb over the crates situated near to the sidewalks.
- Cargo is based on the ship from the mission Crew Expendable and multiplayer map Wet Work from Call of Duty 4: Modern Warfare.
- If several certain hidden stuffed animals are destroyed around the cargo holding, beach balls will begin to fall in from the sky.
- This isn't visible to players, but there are spurts of misty water that appear around the sides of the ship, as if it's being hit by waves.
- The water surrounding the ship has no waves and is unusually flat.
