Call of Duty 4: Modern Warfare is the Games for Windows Marketplace Deal of the Week. The game is on sale as PC download for $14.99 until Wednesday, June 15. This matches the price that was on Steam for the Midweek Madness Sale, but that deal’s over now. This is a great game. Played it a lot on LAN back when it first came out. It has a 92 metascore, which is damn good. Single player is really fun too.
