Hi it's been awhile, but its because I was in a gamejam and finished the jam version of a new game for s&box; the source2 gmod successor. if you have access to it, you can find it here: Hand Clans - mbrawls - s&box (asset.party)
Everything except the source code (i just cross referenced it i dunno how to code from scratch :,) ) and the default dev_sky texture in the debug map was done by me alone; including the models, textures, the firing sound, and animations. I'll hopefully keep developing this project as s&box continues development and have it ready to play whenever the full game/engine/whatever it is will be releases!
