(adsbygoogle = window.adsbygoogle || []).push({}); i was soloing ...and i used to run my rapetrains in the Biodome.
well, what happened was the following, i got overrun by zombies and decided to use one of these tabs(these things that let u jump in the air and i was directly jumping in front of a carpenter that was blinking and exactly at the moment that i got it, it changed (at the very last second) to a perk!!! btw: i got phd flopper and i already had jugg, speed,revive and mule kick
for those who play alot on solo, then you might pay attention to the power ups that appear in the Biodome!!
and sry that i cant proof it with any video or pic, but i am already trying to get it again(and recording at the same time)
feel free to tell me what you think(but dont hate on me, i know i was a f#cking idiot cuz i didnt took a pic, but i had absolutely nothing to take a pic or to record
but hey at least now we/i know how to get a fifth perk

mmmm.... ill try this later, thanks for the post!

there is a botton for that but anyways im still trying to get it again...

if u do it again can you please tell me, try to record it with your phone, because I cant seem to do it.

yes im trying to get it again and to record it but it is really hard instead of getting the perk(which is really really hard) i ll wait for a power up turn into a perk(just to give u a idea of how hard it is and how lucky u must be to get it)

You can also hack a normal dropped firesale i think it is and you can get a perk but it costs 5000 i think i heard

Ill give this a try when i go to my friends later and see if i can get a good video of it.
