Boot up the Playstation Network today and you'll be able to download the latest map pack for Infinity Ward’s Call of Duty 4: Modern Warfare.

The Variety Map Pack features four new multiplayer maps including “Broadcast,” featuring tight corridors and wide open parking lots; “Chinatown” where night battles well lit by the full moon can play havoc against a backdrop of brightly colored lamps, antique shops and neon signs of the local district; “Killhouse,” a desolate warehouse under enemy attack where squads will need to move through building mock-ups and plywood walls in order to take control of the combat arena; and “Creek,” a wide open village in a heavily wooded area where battles are fought among high ridgelines and deep in underground caves.

To celebrate the launch, PLAYSTATION Network will host a Double XP Weekend, where players can earn twice as many experience points as they battle gamers from specific playlists on the new multiplayer maps starting at 12:01 GMT, Friday, April 25 through 11:59 PDT, Sunday, April 27.

Gamers will also have the opportunity to play with developers from Infinity Ward on Friday, April 25, from 2 p.m. to 5 p.m. EDT and 8 p.m. to 11 p.m. EDT. Make sure to add the following PLAYSTATION Network IDs to your friend’s list:
