Currently setting up some missions, while balancing the ships to match up well against vanilla opposition.
So far, here are the Blackrock ship systems:
Desdinova: Arcjet Burner - after the first time you see a Desdie ram into a wolf at 350 speed, then shotgunning the poor frig in the face with its Squall Cannons at it spins out of control overloaded from the impact, you will never want to deploy any other destroyer, ever again.
Nevermore: Lucifer Generator - Overload the Nevermore's complex generator system for 3 seconds, locking the steering thrusters and main engines, disabling shields, and giving double energy weapon damage for a short duration. Generally speaking, this system has hard synergy with the built-in Antimatter Lance, and lets you truly put out the hurt on ships if you are skilled at aiming and anticipating enemy movement. See a frig that's close to overloading? Pop that sucker! (provided you are a true baller)
Revenant: Barracuda Drones - Heavy combat drones that excel at destroying overloaded vessels. Featuring two light mortars and a vulcan, these aggressive drones can tear through armor and hull, but are not especially good against shielded fighters, or at destroying missiles. They are also unshielded and only have a thin armor coat to protect themselves.
