finally went ahead and grabbed it off itch. gonna give this a go 
EDIT: this thing is awesome! had great fun toying with it but having issues implementing it into my own project. i exported the input setup which eliminated my first issue but i am unable to interact with any of the objects. i simply imported the input presets, dropped the weaponmaster folder into my content folder. trying to sort out what else i need to do to get it working in my own project, any insight?
EDIT 2: so yeah after toying with it for a while i cant get it to work in my own project. really hope somebody can help me out here on how to implement it into an existing project.
