Shadow Complex Golden Guns

There is a secret unlockable room in Shadow Complex that contains a golden version of all the guns you collect during the completion of campaign. Once you have unlocked this room, anytime you start a new game or continue an old game, this room will be available giving you access to the golden gun of your choice. The beauty of it, this room is located right at the start of the game in area B5.

To unlock the golden gun room, collect all 12 Gold Bars hidden throughout campaign. Once you collect the final gold bar, the room will unlock and show on your map as a gold star.
