Hey, I created something that's not for HeXen!
VZ-64 Škorpion. I always felt that this gun is retro and weird enough to fit in DooM. Also the wooden handle kinda reminds me of the style of DooM shotguns.
I got the model from
https://gamebanana.com/models/2780, modified and rendered it with blender 2.8. I was going for the DooM style lighning with the green backlight like on DooM pistol.
So far I have done almost every configuration I can imagine the weapon could be used - folded and unfolded stock plus animation, two weapon side view, reload and ironsights. I will try to improve the hands a little and do the reload and unfold animations later.

Feel free to use and credit the author of the original model too - Samm Varnish - he is 5 years innactive on Gamebanana and I wasn't able to find him anywhere else, but credit is due anyway.
