Well save ammo and dont run always becuase the can hear you walk sometimes to past the
zombies :d

hide your doctor in a corner while you have your standing guys go and save the sherif
be sure that your standing guy has a gun as it will greatly help early on as well as the
axe
once the sherif is free'd give the Axe to the sherif as he has moar damage with mele
weapons but les speed! make sure to use the gun to stall the faster enemies...one shot
that hits should stop them and if your close enough then the sherif will attack imidiatly
if you have the enemies targeted
