SweetZombieJesus...u can prob figure out that a gas cylinder will explode when u shoot it...and a bear trap will "TRAP" the zombie (bit obvious).....when u hav a survivor and a weapon all u hav 2 do is drag the gun and put it on the slot saying "PUT GUN HERE"!!!!!!!!!!!!!!!!!!!!!!!!!!!!
The reason ur survivors r dying when the barricade is up is because the weapons can reach over the barricade and kill them.........it does also say at one point that the zombies now have weapons and things "could get nasty"....
All in all a challenging, exciting and fun game...excellent game, 5/5
