The Prawn Suit does not take collision damage, rendering this upgrade useless for it. This upgrade provides the Seamoth and the Prawn Suit with a system that preemptively hardens the vehicle chassis prior to collisions with terrain, eliminating damage under normal conditions. It is available in Subnautica only, not in Below Zero. The Hull Reinforcement is an upgrade module that can be crafted in the Vehicle Upgrade Console.
