Modern Warfare 3 multiplayer free on Steam this weekend

Did you know the weekend technically starts now? According to Steam it does, anyway. Don't even bother showing up to work tomorrow.

Steam users will have access to Modern Warfare 3's full multiplayer suite of modes starting right now. All you have to do is install the game and you can play as much multiplayer as you want until Monday -- unless you want to buy the game, of course.
