As Rae pointed out yesterday, the new Battlefield 3 expansion has been released on PSN for BF3 Premium subscribers. Four new maps, three new modified vehicles, and a new scoped crossbow are included. Also the expansion adds the Scavenger game mode where gamers begin with only a pistol and must seek out more powerful weapons. The DLC is also available to non-subscribers at a cost of $14.99. The Xbox 360 and PC version for Premium subscribers is set to be released on December 4th. Meanwhile the regular release for non-subscribers will land on December 11th for PS3 and December 18th for Xbox 360 and PC.
