The Mirror Assault Cruiser is one of the very few really cool ships in this game. A Big Cruiser that is actually capable of generating at least a bit Firepower AND does actually look good IMHO. Whoever had the idea of this must have been a genius.
Yes i do myself use the Nomad Nacelles all the time, they give the ship a certain hod rod look imo.
But i must say i bought the Nomad some years ago when Cryptics actually was releasing additional ship parts without any gadgets, like 5 Weapon slots or consoles. Can you imagine that! So i don't know if that works with the Fleet ship parts.
