When bulldozer II isn't enough.
Backstory: Sometimes you have to improvise, which is the explanation of how this armor came to exist. When scavenging a Junk yard , a survivor grabbed all of the metal he can find and drilled it together to create this thing. It made him extremely slow, but it was able to save him from getting flung by diggers and brutes, so as he did with the ripper, he sold the armor using the spare metal he grabbed.
The model took way too long to make.
