“Activision will be hosting a Free Weekend for Call of Duty®: Modern Warfare® 3! Pre-load the game now and be ready to play when the free weekend starts on Thursday, February 16th at 10am Pacific Time.“
For those who are not familiar with Steam, it can be though of as the Xbox LIVE and PSN equivalent on the PC platform since it does similar things but is much more open.
If you already have a Steam account but not Modern Warfare 3, then click this link here to start downloading the game. Otherwise you can wait till it appears on your Steam games list when the free weekend starts and download it then.
Once the game has been fully loaded it will unlock on Thursday, February 16th at 10am Pacific Time and then start playing with the full multiplayer experience!
If you haven’t played Modern Warfare 3 yet this would be a great time to try out the multiplyer to see if you’d want to purchase it fully. Even if you own the game on the consoles then it would still be interesting to try it out to see how improved the graphics are on the PC version (asssuming your PC can handle it) and what it’s like playing with a keyboard and mouse!
Note: The free weekend does not include the campaign mode.
