Take a look at their weapons and shields. Most transports make nasty anti-fighter units (Skiprays, Lamba-classes, Sentinel-classes, and Storm Trooper Transports are all quite good fighter killers) while many also make excellent anti-capital ship units (Skiprays again, Storm Trooper Transports, and ATR's). It's really the weapons that give you all you need to know about their purpose.
There were flame-spider in Arcanum. Terrible buggers, all sizes from "why can't I step on you" to "instant arachnophobia" could spit fireballs and did extra fire damage with their melee attacks along with poisoning you. Bad as that all is, it's the fire damage obliterating your equipment that was the worst bit about them.
Oh, and uh, new long term projects certainly sounds shiny!
Acclamator-Class Star Frigate (Illegal) This has to be the scariest pirate cruiser ever built. evgr.gif If ignored it puts Battlecruisers in jeopardy. The main armament consists of dual Turbodisruptors and dual Mass Drivers, with quad lasers for close contact. The point defense system was scrapped in favour of a complete missile jamming suite. zbuttrockwy7.gif Multiple proton bomb launchers round off the weapon systems. blink.gif This can kill any Capital-class warship single-handedly, although an Imperial IV-class Star Destroyer might prove a challenge. Era: 10BBY Onwards
Venator-class Star Destroyer (Illegal) Self-escorting mobile deep-space fortress. evgr.gif Slugthrower guns and sensor jamming enable this assault carrier to shrug off endless waves of bombers, while the massive cargo of illegal snubfighters and dual turbodisruptors wreak havoc throughout the system. unsure.gif Only the richest organised crime syndicates will be able to build and maintain these pirate cities. Era: 18BBY Onwards
Okay, that makes me feel a bit better. I'm just anxious and nervous that somethin' might happen and it not show. I mean, you understand, I'm sure you've seen a lot of ambitious and promising projects die for whatever reason. I'm still fired up about 1.2.
