double xp for a week deffo something you dont want to miss out on. i was playing on thursday/friday and everything was fine 200xp per kill but then all of a sudden it stopped and was very annoying. i had a look at forums on mw3 website and activision and loads of people experienced the same problem anyway if you are try this fix.

clear system cache from hdd
delete mw3 title update
delete and re install the game to your HDD

this worked for me and others aswell.

hope this helps

I did notice it happened to me for a few games too but sorted itself out again.

yeh im not sure why tho. this one guy was complaining to activision he had lost out on 48 hours double xp because of it and wanted them to make up for by giving him an aditional 48 hour double xp after this run has finished at 2am monday morning lol moderator told him where to go lol
