[quote name='Exu']I don't get it, I'm just getting an ad asking me to buy the map pack (lol no), there's nothing there about any code.[/QUOTE]
There is one promotion going on right now where if you are one of the first 4500 rewards members to buy the map pack, you get the Zack Levi MP character.
The other is the scavenger hunt, you have to go to the site to see it, there is an ad for it on the front page. One way to get extra entries for the scavenger hunt is to buy the map pack as well
