Want to see what all that Modern Warfare 2 fuss is about, PC gamers? Then play the game's multiplayer mode for free this weekend, courtesy of Activision and Valve's Steam service.

That "weekend" starts a little early, as the free Call of Duty: Modern Warfare 2 multiplayer action starts Thursday, April 8. You can pre-load the multiplayer portion of the game through Steam as of right now to ensure maximum play time without spending anything but bandwidth.

Sorry, but you won't be able to burn through the game's compact single-player portion during your comped Call of Duty time. But free is free.
