Premium Call of Duty Elite Subscribers got a couple stocking stuffers on Christmas Eve for use in Modern Warfare 3. They'll get an extra two hours of double XP play, and a Prestige Token that can be redeemed for more XP time or other perks in the game's Prestige Shop.
Beachhead Studio and the Call of Duty Elite team sent out the notice to subscribers earlier this afternoon, so if you are one, check your email. The goods have already been deposited into your account. The two hours of double XP will kick in next time you play the game. To see your remaining time, visit "Barracks" in Modern Warfare 3's multiplayer menu and look for the gold XP icon at the bottom of your player stats.
The Prestige Token has also been automatically added to Elite subscribers accounts. Again, choose Barracks from the multiplayer menu and then Prestige Shop to see what you can buy with it.
