Like the Back to Karkand expansion pack, Close Quarters adds ten new weapons. But these weapons aren’t available immediately. To unlock each new weapon, you must complete an assignment that requires you to fulfill a set of specific tasks. Upon the completion of an assignment, a new weapon is unlocked along with its associated dog tag. Like the weapons included with Battlefield 3, every primary weapon has its own unlock progression, allowing you to equip new accessories such as scopes and rail attachments. No two weapons are exactly the same, so get to know them and select ones that best reflect your style of play.
