Gameplay
The level begins with Frost, Sandman and their team of Deltas, swimming through the flooded, submerged Brooklyn Battery Tunnel and into New York Harbor. There they rendezvous with a team of SEALs and continue toward their objective. The depths of the harbor are filled with mines and the player is instructed to navigate around them using a mine imaging sonar device.

After successfully passing through the minefield, the team then plant charges on an enemy submarine. The charges detonate and the submarine is forced to surface, allowing the team to board. Frost and Sandman enter through the sub's access hatch and fight their way up to the bridge. The two of them breach the room, killing all the sailors within and their captain. From the bridge, Frost and Sandman are able to launch the Russian's missiles against their own fleet.

Frost and Sandman board Zodiac watercraft that the SEALs have put in place, and make their escape as the battle for New York Harbor rages around them. They are then extracted by a CH-46 Sea Knight and flown away from Manhattan.

Intel
6. Once inside the submarine, be on the lookout for a room that includes a few bunk beds. Walk to the last one, then look in the corner for the intel.

7. On the second floor of the submarine, the intel is in the fuel tank room located just before breaching the missile control room. All of the enemies in this room have laser targeting on their guns so it is hard to miss. Get up on the scaffolding to grab the intel.

Trivia

 * The Statue of Liberty is visible in the level, in the distance, surprisingly intact despite the chaos of the battle.
 * In the submarine, on the bunk bed, there is a magazine called "Gossip and Lies", which has a picture of General Shepherd, titled "Shepherd in Trouble".
 * If the player stays on top of the submarine too long, a Hind will come and kill them.
 * There is a gas tanker in the tunnel that says Schoefield and Condry, a reference to the Sledgehammer Games employees.
 * At the end of level in the Zodiac assault boat two USMC CH-46 Sea Knight helicopters will extract Metal, but the subtitles say Chinook Pilot and not Sea Knight Pilot.
 * Similarly, the briefing cinematic subtitles refer to the fighter jet pilots as "F-22 Pilot" despite showing F-15 Eagles.
 * The MP5 given to the player is suppressed, while the USP .45 is not. This is similar to "Crew Expendable" in Call of Duty 4.
 * When the player and Sandman are escaping, the player can shoot the boat with mines until it explodes, but not the other one.
 * In the tunnel there is grafitti that says sledgehammer, a reference to Sledgehammer Games.
