Okay, so since I don't know how to make/have a model of the Eclipse, I improvised by taking a bunch of Star Destroyer models and mushed them together into an abomination XD. I've also explored the possibility of making a superlaser at the front of the Eclipse with methods that involve a medical frigate model and a bunch of Imperial ship turrets. TL;DR This will take a while.
A map based on the Galaxy Gun is also in the works.
