After sitting on hold for 2 hours with Activision, I finally got an answer about the premium 2 hour double xp.
I got the Hardened edition game at the midnight launch, registered the elite and started playing. Due to my system being at work, I didn't want to use the available 2 hour double xp I showed as having. When I got home i plugged my system in and found that the Double XP option was gone.
So I called and sat on hold for 2 hours, and finally got a support rep. He told me after conferring with his boss that the 2 hour double XP option is only available for the first 2 hours after activation. If you don't activate it within two hours of activating the elite, you LOSE the option of having it. Now this doesn't mean if you activate it you have to play it all in 2 hours, it is earn through 2 hours of game time. But you lose the option of having it within 2 hours.
This is the OFFICIAL word from the thieves at Activision. I will be calling the corporate office when they open in half an hour and *** them out. Since I am also the host of a Radio show that is heard internationally about gaming, you can frakking guarentee this is a topic on Sunday, as well as their lack of support.
