After 10 years, and 5 years of hard work and testing, the XWA Upgrade Project's
official model of the Executor-class Super Star Destroyer is finished
! The model is based on the original model by Enterprise E, with many tweaks and modifications to textures, all pushing game engine limits, by General Trageton and Dragon (the latter who is now an official member of the XWA Upgrade team).
There are more screenshots thumbnailed on the forums, and you may find the OPT in the downloads area (an original error in the installer script has been corrected by Darksaber).
