Call of Duty: Modern Warfare 3 has received its sixth title update since the game's launch; a patch which addresses lag and a number of glitches players have been exploiting for their own nefarious, personal gain. Gone are the days of melee-jumping, as well as clan tags which use the controller's symbols to spell dirty words. (Bal[LS] indeed, sir.)
A number of guns have also been tweaked (see: nerfed) as hotfixes introduced to the title. You can check out a full list of these readjusted armaments after the jump, and pray that your precious, precious firearm evaded the developers' all-seeing eye.
