(adsbygoogle = window.adsbygoogle || []).push({}); Oke, we where doing this old Five glitch where u have to kill the docter underneath the trap and u can then stand under the trap and kill zombies in front of ya..

On the docters round my friend got his HK-21 stolen and went to buy the box, he bought an new HK-21 and we killed the docter, and he had 2 HK's 1 was upgraded 1 was not.
But we do not remember how we did it, because theirs an couple cenarios:

1. Get ure upgraded HK-21 stolen and buy an non-upgraded 1.
2. Get ure non-upgraded HK-21 stolen and buy an new 1 and upgrade it.

Then the next step is:

1. With what wapen in ure hand do u need to kill the docter so the other HK-21 does not dissapear?

we have tried couple of times but we couldnt get it to work anymore. SO im asking for help people go figure out what the way is.. Because its possible with rayguns (i got mine stolen and bought new 1, but it dissapeared because we diddnt knew how to keep it anymore)

I'm still figuring out when im playing but their are so many different ways for it!

It will be exactly the same as a ray gun and this is a very good find as its basic and easy to do. Also there another way to get to of any gun its on my youtube channel heres the video link:

And if you want help add my PSN:zJezzah i will help you, if you still need help

The video you posted is where he shoots himself?
Thats just based on luck, because when u buy the box you should get it right away. With my method u have all the time to buy the box, because the docter will stay anyway

Yh you can do this method loads of times aswell they are very similar
