"A graveyard of rotting [or add decommissioned here] ocean liners has not only given birth to a shantytown of locals, but a mid-sized Multiplayer Map populated in chokepoints; providing the perfect setting for shoreline-based combat."
The large, black cargo ship outside the map is called the "Infinity Raven", an amalgamation of Infinity Ward and Raven Software, co-developers of the multiplayer maps in Call of Duty: Modern Warfare 3.
There is a family-owned grocery shop near the PMC spawn called "Raven Grocers", another reference to Raven Software.
