This guide covers all collectible, hidden weapons in Battlefield 4’s single-player campaign, and the multi-player ones unlocked through it.
There are several weapons hidden throughout the different campaign missions. You can check your progress towards collecting these hidden weapons in Battlefield 4’s stats menu.
They are displayed next to your collected Dog Tags.
