DylanThibodeau wrote So I was playing zombies with my friends and I randomly got an insta kill and after knifing a couple of zombies I got a green burst thingy like when you get a perma perk... I went back into theater to make sure it wasn't a power up and it wasn't... does anyone know what I couldv'e gotten?

If you were near the fog you could of just killed a jumpy thing without nodicing

I wasn't near fog I was in a building where you can build the electric barrier

See if you knife faster or see how many rounds it is 1-hit knife till.

I will post the clip of it as soon as I figure it out

I got that around 4 with the galva knuckles I don't think it does anything.

If it doesn't do anything it wouldn't of happened. I got it from a regular knife im about to upload the clip

cool video im going to try it

Are you sure it wasn't a carpenter because I know those do not make an animation on your screen after getting them. It also looks an awful lot like a power up, which the permanent perks might be like.

I watched it twice. It definitely looks like another perma perk but without more info it's pretty hard to try and figure out what it is. What was your stat line for the game to that point? kills? melee kills? etc
Did you notice anything different after? Like maybe a faster knife or a stronger one. If it's a perma perk, whatever effect it caused you would still have so you should experiment to figure it out. Get a friend and compare how many knife swings it takes to kill a zombie and how fast it is. Also possible it's not knife specific but could be just from the kill. who knows.
