Guys,
found this, and first glance thought, oh it is just Mike Myers...but no...have a read, as it might be owrth giving it a go at some point.
The way it works is, one player is a zombie while the rest of the players are all humans. The zombie class is SMG/Juggernaut/Extreme Conditioning. The human class is any weapon/stun or flash/Special Grenades x3/no Juggernaut or Extreme Conditioning. The humans can't shoot or attack in any way, all they can do is run and throw stuns or flashbangs. The zombie must hunt down and stab the human players. The radar is always on and if a human dies three times, he/she must switch teams and become a zombie. When there is only one human left, that player can fire his weapon until he has four deaths. The last surviving human starts as the zombie next round and can choose the map to play next. The humans can't glitch or go to any difficult to reach areas.
