The nightshade, as with most modern mako marine vessels, features systems made with incorperated alien tech. due to the scarcity of replacement mako marine parts in more remote parts of europa however, most of the sub was designed to be able to use standard issue parts found in shops across europa, the fabricator comes preprogrammed with recipies to modify standard engine parts into ones compatable with the engine or reactor. despite this there are a few systems that require direct parts ordered in from mako marine, which ranges from the oxygenite carbon scrubbing crystal located in the oxygen generator, to the dementonite hull mesh, these systems should only require replacement once every 5 years however

Oxygen generator
the nightshades oxygen generator features an artificial oxygenite shard designed to scrub co2 and other hazardous gasses out of the air , this shard is highly durable and unlikely to break from wear and tear, but will eventually become fully saturated and unusable after around 5 years of constant usage

Dementonite hull mesh
the entire hull of the nightshade is coated in a dementonite alloy micromesh, this mesh perforates through the entire hull and is designed to assist the crew with ship maintence, after a breach is repaired the mesh then goes to repair the hull back to its original state, keeping it almost factory new. this process is not immediant however and will take hours to days to get back to a fully repaired state. this system however requires occasional infusion of new dementonite alloy as with wear the ammount of alloy present in the hull will get streched thinner and thinner. there is an access pannel to reload the alloy in the floor of the bridge next to the mesh controller, a computer designed to manage the mesh and feed it data so it can properly repair

Reinforced infoglass
using a simular form to the microstructures found in some of the walls of the ruins, a combination of microcircutry and structural reinforcements were merged into the glass of the nightshades cockpit and cargo bay windows. this form of glass is highly damage and pressure resistant and acts more like a metal than a traditional glass window, and is able to both display information like a screen as well as be interacted with like a touchscreen. in the event of breakage an emergency the fabricator comes preprogrammed with the blueprints for a repair tool designed to seal over the crack and release a form of gel that will harden within seconds and provide a new matrix for the dementonite hull mesh to repair and regenerate the lost microstructures within the glass

A.I System
while not common in all mako marine vessels, the nightshade features a built in AI system called Solarium. this ai was designed to manage autonomous tasks across the ship as well as inform its crew of the ships current status through infoscreens or the intercom system. for shallower waters this ai also features built in autopilot
also the A.Is avatar looks like tomatos emotes kinda

Autodoc system
while the nightshade features an autodoc the system wasnt entirely designed to function as a ships medic, rather was designed to be more of a nurse, designed to follow the commands of the medic in order to assist with operations and whatever is required. however in the event of emergencys where the medic is comprimised or otherwise not availible the autodoc can be used for basic patch up jobs or to keep someone stable long enough to get back to an outpost for medical treatment
