I would appreciate so much if someone post it here, I want it to change the weapons and basically have fun with it. Also by this way I could play against regular, hardened or veteran bots instead of spawning dumb bots with a mod menu

Thanks !
Edit: okay I got it, but now I get this error: https://gyazo.com/9ca7c122ea36c8dfd62d6a27425a3fd9
Where is the mistake? Thanks
