COD4 will have User Created Content

[Minty]

If you check out the official Call Of Duty 4: Modern Warfare product details (located here (http://www.xbox.com/en-US/games/c/callofduty4modernwarfare/details.page/)), you will notice that it is listed for Live User Creatable Content.


Whilst no-one knows for definite what this means yet, it looks like gamers will be able to create and submit content for download from the Marketplace. This is certainly a good sign for gamers of things to come in the future, and also because it means that COD4 will be permanently evolving online.

That could mean the whole class creation thing, or liek far cry when you create maps and when people join the game they download your map
Should be interesting to see if it isn't the thing with adding perks etc. to your guns
