Call of Duty: Modern Warfare developers Infinity Ward are currently working on more customisation slots for multiplayer.
Currently there are only five slots but with such a wide variety of weaponry to use, there is so much room for more than five.
Even though it's possible to change your loadout during a game, it looks like there won't be any more than five classes that will be added in the near future.
