Add a new "Carapace Armor" blueprint that lets you use psi beetle, burrower, and crab carapace as armor bases to create metal armor-esque armor.
you can use additional carapaces to reinforce the base carapace, but you won't get the bonus effects of secondary carapaces.
(or just change metal armor bp to plate armor bp and let it use carapace.)
Let the legend of Crab-Man be born.
