This challenge is part of Fortnite Season 4 Week 2 XP Xtravaganza Challenges and you'll have to eliminate a total of seven opponents using common weapons. The title of the challenge may seem disturbing to you, but these are the basic weapons, which appear in gray in your inventory.
Needless to say, you'll find these weapons absolutely everywhere on the ground — in cities, in landmarks, or even in the middle of nowhere.
To succeed in this challenge quickly, the easiest way will be to land in cities, especially those that are close to the starting point of the battle bus. Take to the ground with a common weapon and then go hunting for players.
Also, try to pick up shield potions along the way, which will give you the edge in early game battles. Most of the fighting will be hand-to-hand: the most effective grey weapons will be machine guns, or even pistols. The gray shotgun can hurt a lot, but it's still a bad weapon...
As the game progresses, your grey weapons will become less and less effective in winning duels, since your opponents will often have very good equipment on them. Play aggressively from the very beginning of the game!
