I once played in campaign, and i decided to replace npc weapons at arc9 weapons and through 150 kills i saw spear in my inventory, all sights, lasers and etc is from mw addon, but this weapon missing in pack, in description it's made by same person who made other weapons in mw addon, i even tried find it in addons folder, but i didn't found any props with spear name (or i'm dumb and blind)
