  This is the other infected counterpart to zombies. LD4 zombies are those scary running zombies like in Left 4 Dead, 28 Days Later, and contradicting to the name, Zombieland . Remember that all the rules that apply to the Zombie Survival Guide are now forfeit. You do not need to aim for the head to get a kill but instead can get a kill by shooting the sh*t out of them. So get an automatic weapon and/or a semi-automatic weapon as opposed to a bolt-action rifle to remain a survivor since speed would be a neccecity to eliminate the infected.

   But there is one rule from the survival guide that applies to LD4 zombies are that you MUST stay away from urban areas. Logic states that the more people in a environment the more zombies should be around. Of course LD4 Syndrome is a virus that does not kill and reanimate so instead the infected individual is still in a technical standpoint alive, which means that the infected must eat and drink as opposed to zombies which have no need for food or water. So the best course of action would be to retreat to an isolated area and wait out the epidemic.

      I hope my short summary should weed out the significant diffrences between LD4 zombies and actual zombies and thanks to Max Brooks for the creation of the Zombie Survival Guide.
                              Good Luck :)
