Xbox Live Free Weekend for Xbox 360 Owners
This weekend if you are an Xbox 360 owner you’ll have free access to multiplayer games. Starting with today and until October 12, you can play with your friends whatever game you want even if you are a Silver member.
You can also play Warface and World of Tanks, because they are free to play as well, even if usually they require Xbox Live Gold membership. For more details see the source link!
