Start to post this in small suggestion topic. But Finally post here, because is longer to explain.
when aiming a zombie, there is too much damage on structure around. I affraid to fight zombie on my builded stairs, in corridor safehouse, side to crates. because each time I hurt the structure too, even with hand ! Are we as clumsy, even at lvl 10 ?
Should be only damages on the zombie when aimed.
Tools needed to destruction is not enough diversified (everything with sledgehammer) and not match to the most efficiency tools :
wire fence and wall, barbed wire (IRL with rebounce , you can't effeciency destruct a this kind of wall with sledgehammer) could maybe destructed with a saw (as the picture of it is one of metal saw !! ), by blowtorch or adding pliers.
Metal walls are at the limit, is it a really strong wall ? so seldgehammer coulb be useless and use instead blowtorch.
tissue based objects (carpets, curtains) should be destructed by other tools (may scissor)
builded structures damages by weapons aren't selective enough. You can hurt everything with hands, axes,etc.. :
assuming that punch a metal wall (what about wooden wall ?) could only result in a fracture for human, and others hardness limit.
Wooden base : axe, crowbar, (hands ? really ?), sledgehammer, fire weapons and bunt weapons with malus
solid metal base : sledgehammer, fire weapons with big malus
wired metal base : axe (with big malus)
