While Call of Duty: Modern Warfare 2 is out I think that now is a good time to list some of the objectives necessary to get the golden weapons in Call of Duty 4: Modern Warfare.

Instructions

1. Step 1

Play game without cheat to get the real effect....corrupt spoils the game. Of course, this how to do not involve cheating it involves skill, so you can cheat then you have to seem elsewhere.

2. Step 2

You can release the golden weapons by fulfilling confident requirements.

AK-47 - Complete all Assault Rifle challenges
Desert Eagle - Attain Level 55
Dragonuv - Complete all Sniper Rifle challenges
M1014 - Complete all Shotgun challenges
M60 - Complete all LMG challenges
Mini-Uzi - Complete all SMG challenges

completing the challenge are pretty tough, but you have to think can do it then go ahead and give it a try.

3. Step 3

The weapons to look cool, but not to carry out better. They don't work like that. Having the guns is additional of a pride thing; saying that you were able to get all the golden guns is a great accomplishment.
