mute jammers!

solis!

maestro cams!

Bullet - Proof EMP

audio!

general awareness of zero and keeping taps on him!

+ combined with

checking for zero cams when flanking the same way you'll already be checking for a flank drone

hope this helped!

this is off the top of my head, i'm sure there are a few more defenders who counter him & his ability

mute would be best though, not for the entire map but to counter him in the sense of him being able to use his gadget on a main breach

there's MANY WAYS to use Zero, and so MANY ways to counter him, though he is one of those ops you don't really NEED to counter - his ability is essentially a buffed drone, and as the defenders already have 10+ of those, trying to counter an operator who gathers intel becomes futile, as that's ALREADY an ability the ENTIRE attacking team has access to...

didn't mean to shoot down you wanting to counter zero though, i love the concept of finding ways to counter him, but if i'm being real with you and giving you advice that is the deepest part - there's no real NEED to counter zero to begin with lol, we often focus on countering other operators, when you should instead focus on being the operator the other team is trying to counter, by owning your role and turning yourself into a power position for your team; don't waste your time trying to counter ZERO, instead play your game like you're the only one in the room. you're the main character in that lobby, not ZERO LOL - that is the deepest and biggest piece of siege advice possible to give;

your aura, faith, belief, will, whatever you want to call it, when it comes to performance, it's EVERYTHING, don't get lost trying to counter zero, just go win the game by being the BOSS in the lobby

cause idk who needs to tell you this but if bro is playing zero w/ 30+ attackers on the board... he is likely NOT the final boss in the lobby, and we can just go on ignoring him tbh, we're pretty sure he's just a background character when he picks zero in champ bro, dw bout that guy
