The East Dock presses right up against the eastern buildings with a single traversable pier protruding over the water. Midranged fights tend to dominate play when moving west, while longer-ranged skirmishes break out along the extended north-south corridor. Use the available cover to keep out of this long sightline as much as possible unless you’re utilizing it yourself for its sniping opportunities. If you need to get out of sight fast, dive into the water.
Watch out for enemies up high on the far north and south ends as well, where upper-level vantage points provide a means to fire down into the East Dock. Push up against the central building to cut off their lines of sight.
When moving toward the middle, consider your route based on your Loadout. The North Dock path offers the longest sightlines, while heading through the Tunnel or Power Station keeps the fight up close. For a more balanced approach, head through the southern Warehouse.
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.
