There is no shortage of collectables waiting to be discovered in the game campaign of Call of Duty: Modern Warfare 4. Examples of these collectables include notes, contraband, and yellow supply crates found within various levels. Some are easier to discover than others, some hidden in sealed crates or within buildings and bunkers that one may pass by unnoticed while playing. It also earns you a number of achievements. In this guide, we’ll show you where to find all the campaign collectables, along with the keypad codes and steps needed to get them.
All Campaign Collectable Locations
Here are a number of collectables that can be collected in the game Call of Duty: Modern Warfare 4, which include notes, contraband objects, and yellow supply crates. Collecting these objects will assist you in unlocking some achievements like No Stone Unturned, Noteworthy, Time to Crate, and Never Forgotten. These objects are mostly found in three missions: Following Orders, Stranded, and Escape.

Once she leaves her hiding spot, jump down and crouch to read the final note. After collecting all four notes and four contraband items, you’ll unlock the No Stone Unturned achievement.
