Destiny 2 is a game that’s all about grinding for gear, and the latest Nightfall strike offered the D.F.A. as a reward. It’s one of the best hand cannons in the game, and fans were pretty excited about playing the strike until one dropped for them. Heck, one of our writers played for hours and wrote an exasperated post about how the gun probably didn’t exist as a reward.

Bungie has since stated that the rewards were bugged, and weren’t dropping like they were supposed to. For anyone. No matter how many times you tried. Whoops!
