lol i didn't know there was a end
just before i was about to quit i beat it lol it was very very easy i wouldn't even have to heal the wall once if i wanted to (i did just incase) and since you can get survivors to help you it makes it even more easy its tough to know what the best weps are but let me give you a list
close range: chain saw only useful if you have alot of zombies or dogs on the wall
long Range weps:
my favorite was the sawn off not sure if it was the best though its great so is the normal shotgun the uzi is good but not to powerful unless you keep hitting them in the head the sniper is great since you don't have to reload but only if there isn't alot of people the ak 47 is a good mix of power and quickness it offers a quick reload the pistol is actually pretty good but not good enough for lots of people lol (i only named my favorites) it is very important to have survivors as they can help you out but they are more useful if you are reloading a gun that takes awhile they may be slow but still very useful it is useful to have atleast the shotguns and a machine gun everything else isn't very important but can help and i suggest repair the wall when it reaches 95% or lower even though if your good you won't need to repair it at all most likely it is still better to be safer then feeling sorry in the end anyways im done its a great game 10/10
