That "picking them off" deal will work both ways. Don't expect idiot zombies walking upright in the open. Bad guys can also operate a scoped deer rifle, and lay your house under stealthy ambush siege. After recon, they find out who the big stud is, and wait for him to exit the house at dawn. BANG! Now daddy is dead, and the evildoers are still out in that treeline somewhere, patiently waiting for Mom, sis and little brother to come out.
