Ok so I was playing a game when A person with VIP from somewhere was laying mines while knifing and they blew up saying it was knifed. I could see it because it was a REAL hack, So if we can find the right animation for it in Nexon's files. Other people wont see it but you will IF its possible. And It may say it was a knife kill like the real hack. But Idk
I don't know if it will work but I'm 60% sure its possible.
Now I don't make my own mods and stuff but you could do it.
