I'm noobish at this :P

In my opinion, challenges are fun, but since the average player does not have the capability to record videos, people are prone to not have proof, which makes people prone to lie.

I love zombie challenge especially when start fighting for a huge wave of zombies. And killing zombies is one of my asset ;)

I think better title to this would be "Small portion of zombie challenges" since you just can't list all, you can make practically infinite amount of different variations how you have to play a match etc. And new ones are being created all time.
