I thought of an idea about lightsabers, Magicka Sabers from skyrim, but in gmod, the models should be easy becuase most of the lightsaber handles in skyrim and gmod are the same, but what I mean by Magicka Sabers, I mean a different mod all together, here is some ideas for it...
-First person swinging animations
-Steathing and Unsteathing animations
-Kill moves (Maybe) (you might have to make another mod for that)
-Creating a magicka saber
Thats all I have for ideas have fun with this
