GoldenEye: Rogue Agent Cheats

To find the golden gun you must be in the Hong Kong level after Dr. No's helicopter attacks the building(after you open the sliver case). Kill everyone on that level of the building but don't go through the wall where you are suppose to go. Instead to back to where the sliver case was and look back the way you came. Go to your left and crouch down. You should be able to go through the wall(it's right next to some fire, you will go through the fire and the wall.). Go straight through this hallway(still crouched) and you should be able to go through the wall to your left(next to the corner). Then you will be in a room with a cow in a boat. The golden gun is under the cow.
