Treyarch has just released a massive patch for Call of Duty: Black Ops 2 on Xbox which fixes a number of bugs and re-balances several guns.
Once the 32MB patch is installed, all SMGs equipped with a silencer will suffer further reduced range, plus several assault rifles have had their recoil and damage values altered. There are plenty of other changes which you can check out in the full patch notes below:

• Added support for Live Streaming in all Public Match playlists.
• Added League Best from Season 1 to Player Card.
