All Collectible Locations
There are a total of 132 Collectible Locations in Wolfenstein: The New Order – 50 Gold Items, 72 Enigma Codes, 10 Letters. You have to find all collectibles to unlock the following 7 trophies / achievements:
All that glitters [Bronze / 20G]
Heart of gold [Silver / 30G]
The lives of others [Bronze / 30G]
Secrets revealed I [Silver / 30G]
Secrets revealed II [Silver / 30G]
Secrets revealed III [Silver / 30G]
Secrets revealed IV [Silver / 30G]

None of the collectibles are missable! You can search for missing items via chapter select at any time during the story or after beating the story. It also doesn’t matter what timeline you are playing (Fergus / Wyatt). The only difference between the timelines is that you can either pick locks or hack circuits, but the levels are the same and collectibles are unaffected.
Stealth-klling commanders will mark some collectible locations with a question mark on your map (press ↓ to open map). This won’t necessarily unlock all locations though. There are areas that don’t have a commander or you must do little side quests to be rewarded with an item.
As soon as you pick up a collectible it will be saved instantaneously. You don’t have to reach the next checkpoint. Even if you start a completely new game your collectible progress will carry over.

In chapter select you can see how many collectibles you have found per level. Each collectible has its own specific name which makes it easier to identify what you are missing. To see their names, open up the collectible menu during a mission.
