I have to agree with Thu-Kalfireth on this one...
The Hades not only had those funky engine pods (it also had two engines on the back of the hull proper) but its general structure was just, well, wrong. It's turrets are planes flush with the hull in a lot of places (only thing in FS to do this), and it has that rediculous bridge section sticking what, a full kilometer above the deck? If there exists a more useless extrusion on any canon ship I certainly haven't found it. Unless of course it's those two fins that stick off the bottom. As for the model, the mapping is shoddy, it's extremely simple in a lot of places, and it looks like its paths were drawn by a 4 year old.
The idea of the Hades is relatively cool, and certain things could have been pulled off. But the model itself is just junk.
