The story: You're already saying "what in the world is that?". It's the Plunderer, piloted by IG-91 (see the IG-91 page for his story). The Plunderer was a high security light transport in it's 'previous life'. The EU version of an armored car. IG-91 jacked the Plunderer as it was in the loading process, and converted into a pirate ship. It's extremely well-armored, and well-armed, and it's much faster than it appears. It owes it's speed to capital-grade engines, much like IG-88 outfitted the IG-2000 with. Similar to bounty-hunting ships (which this is used for on very rare occasions), this ship can blast you out of the sky, or quickly disable for boarding. Along with the suped-up engines came a capital-grade heavy tractor beam. The ship also sports an ion cannon, two heavy lasr cannons, and an anti-personnel slug-throwing cannon.
The MOC: I went for something very different (obviously) with this ship. It has a very strange and unique configuration, with pretty cool equipment. The parts are spares, some of them as old as - well, let's just say VERY old (most of the blue bricks are from when I was a kid).
Rear port side view. Cockpit, main fuselage, and engine detail. You can also make out some of the comm/jamming array up against the main fuselage under the wing (there is a matching set on the other side as well).
I like the cockpit positioning and the general style/shape. Great ideas at work here. I do prefer SNOT-based wings, which you should give a try with this baby to take it up a notch. Looks good! Cheers!
