This is My Arc Hammer Model I made for using as a mod on the Game Star Wars Galactic Battlegrounds, this was General Mohc's space faring production facility used to supplement the Imperial Stormtrooper Corps with Dark Troopers.
Oh wow, this is bringing back memories for me! It makes me want to find my old copy of Dark Forces and relive some of the old times, although I think your model beats the one from the old cutscenes by quite a bit.
You know I first knew the Arc Hammer when I played an Awesome Dark Forces Campaign made by a really talented guy in the Star Wars Galactic Battlegrounds Forums. He used his own mods of the Mouldy Crow and Arc Hammer, Sadly I dont knew 3d stuff by that time, nor someone who by pure coincidence had a Mouldy Crow Model XDXDXD
