Bo3 Invisible Glitch. How does it work (ps4)?

I'm currently playing Bo3 on Ps4 and some have used a glitch that they are simply invisible and you can't kill them at all. I would like to try this glitch too, but unfortunately I don't know how it works. Does anyone of you know how it works? I look forward to helpful answers.

PS: I was looking for videos, but they are all in English and many for Bo4 Zombie Mode

Thought everyone was pached?!

A month ago when I played that nobody had such a glitch. Mhh good question, I'll be looking for a time for you, can speak English very well

Thanks Habibi

I just think it's ridiculous, it makes no sense to gamble against such people, do you all have such a short one that you need it?

I asked for help and not opinions

Do you really suck that bad that you need a glitch to win… So sad.

Totally defeats the purpose of competitive gaming! Retarded lovers use this glitch. Pathetic!🤣🤣
