"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 cargoship outside the map is called the "Infinity Raven", an obvious reference to Infinity Ward and Raven Software, co-developers in the multiplayer maps in Call of Duty: Modern Warfare 3.
There is a family-owned grocery shop near the PMC spawn called the "Raven Grocers", another reference to Raven Software.
There is a jump glitch on the broken steel window of the southwest ship, which if successful allows the player to get over the window and into a ledge in the corner of the map. On Infected, this makes the Final Survivor extremely difficult to kill, even to attempt a Throwing Knife.
