Well... there is a GTCt Pirahna, a police cutter downloadable from Repirocity [sp?] site. It's nice, even if it lacks the weapon table when it has a custom weapon. It's nice with my turret upgrades, even if a little fragile. [8 fighters can take it out with one salvo of missles and cannons]
The model is cool, and with fine textures. It is armed with missle launchers, normal turrets and custom weapons without table entry. Modified Terran Huge Turrets work just fine.
I, personally, am working on a heavy cruiser [blob turret heavy, but with some big guns]. Unfortunately, TrueSpace is [censored by Inquisition] and it kind of slows the process down. It would be really pushing the cruiser definition, as it is basically a pocket corvette. Something like Aeolus, only larger and better armed.
