No because all the camos are run via the IW Xbox360 CoD4 server. Meaning unless you have access to it and upload a golden camo for the P90 or whatever, there is no possible way of just using a patch to get golden guns for weapons that don't support it.
I am currently working on the Xbox360 version of being able to skin your guns with customs camo's created in Photoshop, as seen in some PC cod4's :lol:
do we know if its possiable yet like in mw2 to mod are custom classes on cod4 for 3 guns 4 perks yet?We can only modify cod4, not really create new stuff that was never put in like a golden p90 (even though it would be sweet)
