I'm trying to recreate Harlock's Arcadia in the game (except for the 3d model, which I surely cannot do). of course, the blu-ray release would be required in order to properly understand the whole thing, but at least as an idea.

who else has seen the movie in order to help me detail the various properties / abilities the ship should have?

EDIT: AFAI Remember, I think this is mostly correct:

Beam weapons which allow for 360° offensive, capable of piercing even the thickest armor and with absurd range, unspecified number of them + 2 main cannons which can only fire up-front and have even longer range, capable of long continuous fire

Turrets for side-flank offensive, standard turrets with bullets, capable of targeting even small strikecraft

Lost Alien technology:

almost istantaneous self-repair capabilites for any non-critical-damage, and even that will in time be repaired

dark matter engine: unlimited energy which allows for extremely fast movements on both cruise speed and turn speed, plus capability of warping to almost everywhere in the galaxy from any point

dark matter shield: shields capable of enduring even the most powerful blasts

sentient AI: the ship is capable of self-movement in cases of dire necessities
