Just wanted to lay out my plans for this race...
1: The Xiion have their own ships, three corvette classes, two destroyer classes, two cruiser classes, a battleship class (a modified version of Freespace's orion destroyer), and a carrier class.
2: completely unique weapons, shields, supports and engines for the race.
3: Xiion vessels have more armor and tougher shields than ships of other races. Many of their weapons have devastating potential.
and now into the vessels, heres what i think one of the Xiion Destroyer classes should look like.
these two images come from X3: Terran Conflict if you didnt know.
I own a copy of that game.... and i have yet to get as SINGLE one of the most badass fighters in the game, the xenon LX, its freaking AWESOME... theres a picture of it below the two pics i have for the destroyer model.
On a side note, the other ship is the Terran Vidar. Its like the Mustang Super-Snake of Corvettes in X3, and i am lucky to own one in that game
