For those still playing Modern Warfare 3 instead of Black Ops 2 for your Call of Duty multiplayer fix, Infinity Ward has taken to their Twitter account to announce that their will be a server outage tomorrow.
And as the result of the outage, stats will not save during the outage. Fortunately, it’s only a scant four hours from 9 a.m. to 1 p.m. PST.

I suggest playing Spec Ops with bots in the meantime? Or better yet, spend some quality time outside before coming back online and pulling off a MOAB or two.
