If you’ve got a Steam account and fancy playing Call of Duty: Modern Warfare 3 this weekend, you’re in for a treat. Starting this weekend until Monday, you have the opportunity to play the game for free all weekend.
The free to play offer only applies to the multiplayer portion of the game. The definitive Multiplayer experience returns bigger and better than ever, loaded with new maps, modes and features. Co-Op play has evolved with all-new Spec-Ops missions and leaderboards, as well as Survival Mode, an action-packed combat progression unlike any other.
