Flood the Market

 "Find the encryption codes in the Stock Exchange and upload them to CENTOCOM."

- Level Description Flood the Market is a Mission Mode Special Ops challenge in Call of Duty: Modern Warfare 3. The player fights their way through the streets of New York to the stock exchange so they can collect several codes placed around the trading floor.

Overview
The player begins the mission in a side shop with an M4A1 Hybrid Sight and an XM25. Once the player exits the shop onto the street, multiple foot soldiers, dogs and GAZ-2975s will block their path to the stock exchange. During the process of clearing out the street, a Mi-17 will drop off more soldiers. After clearing out the street and entering the lobby, several ammo crates await you. Upstairs from the lobby is the trading room, where several laptops are placed on various desks, which must be recovered. Once the records are recovered, the player must proceed to the roof and begin a file download by interacting with the tower on the rooftop. The player must then defend themselves from the enemies on the opposing rooftops while occasionally restarting the file transfer by interacting with the tower. Located on the tower are several Barrett sniper rifles to assist in this. Occasionally the enemies will throw poison gas mortars creating a small gas cloud. After a fixed point, an enemy helicopter will drop off several troops on the rooftop and at another point an enemy MH-6 Little Bird chopper appear, which can be shot down. After the file transfer is completed, the mission will end.

Found in Level
The following weapons can be found with or without attachments.

Trivia

 * This mission is based off "Black Tuesday".
 * In this mission, the player has the same starting loadout as "Black Tuesday" and travels in the same direction.
 * Watch out! Several enemies appear after the player(s) collecting the first intel. They can be easy killed on the stairs close to the ammo creates, before they made it to the intel room. If they not get killed, they will follow the player(s) up to the roof and make a surprise from behind.
