So the Black Ops 2 ‘Revolution’ DLC pack is out on Xbox 360 and Treyarch has updated the message of the day on that system to reveal what many will see as a welcome surprise.
“Starting on Friday, Feb 1st (10 am/PST) and going through Monday, Feb 4th (10 am/PST) you will earn Double Weapon XP on all weapons. Double XP allows to level up and unlock attachments at twice the usual rate”
As of right now, the message has only appeared on Xbox 360 and even if PS3 and PC owners don’t get in on this round its safe to assume they can expect the same treatment once Revolution hits those platforms in about a month.
