How to find missing Weapons?: You can see how many Hidden Weapons you’ve found by pausing the game during a mission, or by checking out your progress in mission select.

It’s recommended you play Battlefield 4 on easy difficulty mode, so that you can move around the more crowded levels easier. Otherwise you’ll constantly get shot at when you’re trying to pick up an item you want to collect.

Note: If you picking up weapons from dead enemies it counts towards your collectibles progress for the “Recon” achievement / trophy. Although it’s not actually needed, but it does speed up the process towards that trophy / achievement.

Does the game save each Weapons you collect?: Yes, the game will automatically save the Hidden Weapons you just collected if you picked up the Weapon, so you don’t have to play to the end of the mission. After picking up each collectible you can safely quit the mission right away without losing collectibles progress, and it’s the same if you accidentally die.
