Wolfenstein II: The New Colossus

In total, there are twelve pieces of gold to find in order to unlock this achievement. More specifically, there are four pieces of gold within each Volume.

Most of these collectibles will require deep exploration as they are usually tucked away in areas that are not always directly taken when tackling the main objective of a mission. Remember, you can always check your mission collectible progress at any time by opening the Journal and referring to the menu's "Extras" tab. Likewise, the game will automatically save any collectibles that you immediately pick up, so feel free to quit the mission once you grab what you need.
