Now we all now how easy it is to raid a base with explosives, even if you haven't tried you should still know. If not, lemme fill you in. To blow up 4 metal walls at once all you gotta do is place 2 c4's around the center of them all. So if you have enough c4s you could just easily completely demolish som1s base. Which isnt that good, and can ruin the good PvP experience some people are looking for while coming to play Unturned. So my idea is to add a new tier of building materials, steel; and along with that i think you should need a smithing skill or something along those lines. Theres not really too much too it. Steel should require at least 2 scrap metal and heat nearby, with the max amount of smithing skill and it should have a much greater durability. Seeing as it takes 10 scrap metal to make a metal wall, it would now take 20 or more. Depending on how much metal it would take to make 1 steel. Can som1 plz reach out to Nelson/Unturned Dev, it would be greatly appreciated.
