I haven't seen one good use out of barbed wires yet. All they are used for is blocking people from buildings. I just ran into this high yield warehouse in search of a soda. this guy had the wire set up so i could pass over it since it was partly merged with the ramp, but I could not leave. I attempted to walk over and it and pushed me through the wall instantly killing me. GG there goes all my gear I spent all day yesterday collecting.
