The Crystanite now have two built-in hullmods on (almost) all of their ships: the Crystanite Core Systems, and the Crystanite Armor.
Crystanite Core Systems are completely permanent, and is built-in on every Crystanite ship. It represents the fundamental design differences between human and Crystanite technology. It increases sensor profile, reduces venting speed, but most importantly it also
prevents any non-crystanite hullmods from being installed on the ship. This means that the Crystanite can now only add their own hullmods to ships, which in turn are incompatible with any other ships.
Crystanite Armor is built-in on almost all ships, and represents the powerful exo-skeletal structure of the Crystanite armor. It grants EMP immunity, changes damage from certain damage types and grants in-combat immunity to coronas. It should be noted that this hullmod may
not necessarily be permanent; it will be able to break from combat damage, turning it into a lesser d-mod version of itself (not fully implemented yet).
The Crystanite have also recieved some other nifty hullmods that you will have to discover yourself! Only Crystanite markets sell these mods, so stealing them or befriending them are the only two ways of getting hold of them (yet...).
