Dome is a small map in Call of Duty: Modern Warfare 3 that has many close quarters combat situations. The two main spawn points are near the dome itself, and near the entrance gate on the other side of the map. The dome covers only a little portion of the map, and serves no significant purpose besides possible defensive set-ups and a spot for players to snipe from. There is a track around the second story of the dome that overlooks most of the map. Nearby the dome is a bunker with two entrances, and there is a bombed-out portion in the middle of the bunker. Across the bunker is a building that has a main room and a back hallway. There are multiple vehicles on the map that can be used for limited cover, one of which is an M1A2 Abrams tank.
There are very few spots that are easy to defend, with the exception of the bunker and the dome with the ladders leading to the balcony, which is vulnerable against air support but provides a good point for snipers to pick off hostiles before they reach a player's main point.
There are twelve oil derricks outside of the map in the surrounding desert.
There is a message written on the dome saying "Beware of bad dogs".
Next to the main entrance of the building, the word "FROG" can be seen on a wall, along with a picture that resembles said animal.
The dome's roof appears to be made out of a very weak material or tarp because some of it is evidently flapping in the wind.
The Abrams tank has Woodland camo; this is strange considering that the tank is stationed in a desert.
Despite the small size of the map, it is possible to survive very long on Survival in two-player mode: each person must cover the ladder going up to the platform which surrounds the dome. The only problem is the helicopters which are airborne, because Juggernauts have to climb making them open to explosives and headshots, while dogs are actually unable to scale the ladders.
It is possible to get out of the map as seen in this video .
This is the only map to allow the Infection game type 'Striker vs Juggernaut'.
This map orignally included Spetsnaz vs Navy SEALs in the beta.
