Find a gun that suits your playstyle

If you ask anyone online, especially on social media, they’re going to tell you to stick with the meta—the best weapons in the game that everyone uses. Right now, most players opt for the AS VAL or C9. They’re excellent, fast-firing, and hard-hitting weapons that make quick work of players. But they’re only a small part of the game.
Personally, I almost always use the AK-74. I like its crosshairs, powerful feel, and its sound design. Do those aspects make for a meta weapon? No, but I still frequently place in the top three on my team. The point is, find a weapon that you enjoy using, then practice with it. You don’t have to stick with the meta, you can still dominate Black Ops 6 multiplayer with any gun in the game.
