A knock is when you down an enemy with a weapon, and it is followed by the dialogue on your screen as well as the kill feed. This doesn’t apply to the Solo playlists as you’re only going to eliminate opponents, but Duos, Squads, and large scale LTMs work this way. When you have a challenge that says ‘Eliminate Players with Pistols” you’re required to eliminate them with a pistol. Obvious, but where players struggle is that they often don’t realize they don’t count for eliminations that you don’t first knock yourself.

If you’re in the heat of battle, it can be difficult to keep your wits about you in order to complete challenges. Your best bet to do this is carrying the best version of whatever weapon type you need to complete eliminations with, even if you see a better weapon later on. Early game is easier for Pistol/SMG kills as few players have shields, but a Handcannon and Purple SMG work wonders even late game.

Knocking out your opponent with an Assault Rifle or Shotgun works just as well, then finishing them off before backup can arrive with your next weapon is your next step. In Squads and Duos, your teammates may need to kill the other surviving members of the player you knocked, so you’re pressed for time. That’s why doing this in 50v50 or Final Stand makes more sense. Players are alive a lot longer, and help can be late to realize a teammate has been downed in all the chaos, giving you more free time to get eliminations.

There’s also another element of the elimination challenges, in that your teammates can also score the elimination for you. If you knock a player, just have a teammate with a Pistol, SMG, Sniper, Explosive, etc eliminate them. You can also do this for your teammates.

For instance, if you knock a player and someone trap-kills them after building them into a box, they won’t get the Trap Elimination for themselves, but you will. This can be helpful, and also makes scoring your own downs more important when playing with others.
