While Modern Warfare 3 maybe the latest and most played Call of Duty title it seems Treyarch are still happy to support their latest title Call of Duty: Black Ops.
So from now until Monday the 13th there will be a double XP weekend for all Black Ops players; on top of that, Treyarch are still changing up the playlists and will most likely add a different 24/7 playlist into the mix.
