From the left border, the Dry Dock comprises a tight rectangle with bulky crates and other large cover pieces, including the small Control Room with openings on all sides. Combat within the area caters to close-quarters fights, though its east-facing openings offer longshot opportunities toward the middle of the map.
The area opens up by the docked submarine, surrounded by pulleys and low railings. A central bridge provides a walkway over the docked sub, and Operators can get on top of the sub and the metal platforms around it.
There are multiple paths east, but the staircase leading up to the Catwalks makes for a great starting route. The Catwalk wraps around the two closed off buildings and extends along the front, overlooking the central Loading Bay. Land precision shots up and down the middle of the map and across to the opposite rooftop. Keep an eye out for enemies near the doorways to either side of the front walk.
Submarines dock for maintenance and refueling at a a naval base on the high seas. Deploy dockside and battle for control over the locale, a midsized map packed with vantage points, flanking routes, and a deadly center ground where only the most stalwart Operators dare pass.
At the top of the third act in Call of Duty®: Modern Warfare® 2 (2009), Captain Price teams up with Roach and Ghost to strike a naval base in “Contingency.” They must secure a docked submarine before its payload can be deployed, though Price enacts a plan of his own that changes the course of the war.
In Sub Base, Operators return to the naval base in a medium-sized Multiplayer map where players face off over the docks and across the central Loading Bay. Take up a position in one of the buildings looming over the middle passage or keep to the ground floor and take the fight directly to the enemy.
