Modern Warfare 2 is barely over a week away, but if you'd rather dump some more time into its predecessor, then today's new Xbox Live "Deal of the Week" is for you. The "Variety Map Pack" for Call of Duty 4: Modern Warfare is currently 50 percent off on the Xbox Live Marketplace, which brings the cost down from $10 (800 Microsoft points) to just $5 (400 Microsoft points).

This four-map bundle includes the following multiplayer arenas: "Creek," "Chinatown," "Broadcast," and "Killhouse." Assuming you haven't already purchased them -- or received them for free with the "Game of the Year" edition of Modern Warfare -- then this is a bargain you probably won't want to pass up. Just be sure to download the maps before next Monday, when there'll be a new "Deal of the Week."
