Death Bone
Recreation of concept art, The Renegade probably made this submarine, though it has a lack of defense but makes up with a triple railgun, loaded with very powerful shells. Though the powerful railgun is made to take out large threats and firing at small creatures can cause more harm then good.
There is a coilgun in the airlock though it is weak and can’t take out very large targets
Update: I accidentally forgot to add gaps near the engine.
