Finding every hidden item in Call of Duty WWII adds significant replay value and historical immersion to the single-player campaign. Players who take the time to explore each map will uncover 33 unique Mementos scattered across eleven story missions. Tracking down these collectibles unlocks the Pieces of History achievement while offering unique glimpses into wartime history.
Understanding Mementos and How They Work
Mementos are specific collectible items tucked away in environmental corners throughout each mission. They range from personal items like lockets and pocket watches to military items like flare guns and gas masks. Finding all three items in a single level requires careful observation, as many are placed off the main path.
Players can view and rotate collected items inside the main game menu to inspect their fine details. If you miss an item during your initial run, you can always return using mission select to pick up remaining items. This flexibility allows completionists to enjoy the action without worrying about missing permanent unlocks.
Finding Collectibles in Early Missions
In the opening D-Day mission, players can discover three distinct items including a knife embedded in sandbags at the end of a trench. The second item requires backtracking after clearing the third bunker to access a newly unlocked room. Finally, checking a table near the barn area yields the final collectible of the beach assault.
As campaign progression continues through Operation Cobra and Stronghold, items remain tucked behind cover and inside abandoned structures. Players should inspect wooden huts, church alcoves, and damaged buildings to ensure no item goes unnoticed. Keeping an eye out for glowing prompts makes searching much easier during heavy firefights.
Navigating Late Campaign Locations
Later missions like Death Factory and Hill 493 present trickier search areas due to dense forests and heavy fog. Items in these stages are often placed near crashed aircraft, dead soldiers, or inside fortified bunkers. Thoroughly sweeping each battle zone before moving to the next objective prevents accidental progression past point-of-no-return triggers.
The campaign concludes with intense urban combat in The Rhine, where the final three items are hidden inside watchtowers. Inspecting every floor and clearing out enemy positions gives players safe access to these last collectibles. Completing this final sweep awards the overall collection achievement and finishes the set.
