One person starts out as a zombie (not the OPS team) who can only knife and tomahawk. Everyone else chooses the OPS team and chooses a class with there favorite pistols (there Humans). The zombie tries to knife everyone while the Humans try to survive, however they can only use there pistols and equipment. Once a human gets knifed they change teams and become a zombie. If a human gets tomahawked they do NOT change team they just reaspawn some where else prventing the humans from camping the whole time and no zombies getting them. Once all except 1 human remains they are allowed to use their primary weapon and try to last as long as possible. Once he dies the first human to turn into a zombie becomes the next zombie.
