yep

You switched from Garry's Mod to Serious Sam?

now it has been added to NRM，and you can use it in NRM list

i use this to create，but look，it said when you create，it must be agreed by NRM author（“You can use your newly added weapon from NRM in the editor until I do that.”）

I'm sorry to break it to you, but you're supposed to add the weapon to NRM yourself

@NSKuber
could you add this mod to NRM，so the player can use this weapon in the NRM list
