you go through the zombie ruin
All you do is combine two regular zombies in the zombie pot (level 25) and walla! It is a rare zombie though, and I believe it was a limited time offer, not sure about that. My mom has one. For more info, just go to the zombiefarmwiki ;)
No, there is no virus that makes you a zombie. The idea of it is interesting to think about though!

To Unlock zombie emotes u have to go a random grave digger event.
though nothing will happen :p
No, I don't believe there is. It would be cool though to play as a zombie. Kinda slow though since they are slow.
Go to any level and go into "Enrage" using the ball.
yes you can do no clip were you can fly and go though walls and god mode is your invincible and you have all the weapons :)
No, Zombie's weapons are there teeth. If the bite you and you 'survive', then you too will become a zombie. There is no way around it (except death). If you are attacked by a zombie though and they eat all of your brain or 80% of your body then you will just die. Sorry, but there is no way to act like the zombie attack didn't happen. You either, become a zombie or die.
You mix a zombarian with another zombarian and there you go.
You need to unlock the basketball weapon and then go on a killing spree with it
