New Maps for CoD4 Modern Warefare: and update ExplainedBroadcast, Creek, Chinatown, and Killhouse.
Broadcast is a map based on the story mode map with the T.V. rooms. It contains 1st floor, 2nd floor, roof top, and parkinglot.
Creek is a huge map that is a hill and inside the hill is a underground tunnel going through the hill.
Chinatown and Killhouse are both maps you will probably find on "Cage" match considering that they are kinda small like the orignal Shipment just a little bigger.
Update: Clan tags are going to be updated to allow some characters that weren't allowed before.
As for Perks and Guns update none have been Announced to the Public yet.
The Update will come out April 3rd. And it will cost you 10 Dollars $ for 800 Microsoft Points.
Please have in mind that Halo3's also getting a DLC which is also 800 Microsoft Points on April 15th.
