Uncharted 4: A Thief’s End: Run-and-Gunner

Uncharted 4: A Thief’s End™
Run-and-Gunner (BRONZE)
Defeat 50 enemies from-the-hip or blind-firing #PlayStationTrophy

Shooting from the hip means that you’ll need to fire your gun at enemies without aiming at them (not pressing the aim button), while blind-firing is when you’re behind cover and you fire your gun over the cover without peeking out with Right Analog. You’ll need to do this 50 times over the course of playing the game to get this trophy.
