(adsbygoogle = window.adsbygoogle || []).push({}); I'm looking everywhere but many people are saying it's patched, can someone link me to a tutorial?

It's not patched. There's quite a few videos and threads out on it.

is it only on ps4 or does it work on x1 also?

PS4
Make sure the account you are duping to is level 1 and has already selected the specialist class!

1. Go on high level account start game go online get a kill
2. Back out to the main menu where it says press start to play
3. Hold PS button on your controller and switch to the low level account (this causes a blue screen)
4. As soon as the blue screen goes away press X (Screen gets brighter and/or makes a noise and says connecting to online service) then press X again
5. If you are online quickly join a match and get a kill. (If it resets you to level 1 go to step 6.)
6. If you are disconnected go to zombies then backout, go to multiplayer and quickly join a match and get a kill.



NOTE: If you get a black screen you waited to long to press X the first time
If you start offline you pressed X to slow or to fast the second time.

How do you dupe zombies?
