Treyarch has announced a new double XP event for Black Ops 2 this weekend. It's set to run from Friday, April 19 (10am/PST) through the morning of Monday, April 22 (10am/PST). During this period of time, players will be able to amass double the XP as they normally would, so it might be a good idea to set aside your other plans and get your game on.
