Which gun is the most powerful in Battlefield 4? None; it’s the bow and arrow.
The Phantom Bow in Battlefield 4 is damn powerful, as the video below shows off. Kotaku reported the news from Reddit, with some awesome editing, music and so many ‘splosions. Makes me want to install Battlefield 4 again!

The new phantom program
It is in the game. It’s unlocked by entering a secret room, entering a secret code.

Check that video, and you can see it.
Tho as of now, no one knows the code.
