it's a glitch, happen from lag. just like how sometimes you open the sprays box and you find 0 sprays there is also glitch for the inventory, only you see this 999, but your partner see something different. one time I saw infinite symbol on a rocket launcher in my partner inventory and one time I saw 999 grenade launcher. It's just lag nothing fishy or cheating. sorry I just wanted to explain so no it's not hack just a normal glitch caused by lag, the game is full of glitches anyway like if you see weapons swap characters hold weapons in slayers from other characters then know it's only lag, and more likely you are the only person who see it others don't it's just bad connection which cause stuff like this. I hope this explains the situation for you. thank you for the video I liked it :)
What you said makes so much sense, i usually see glitches like when there`s my partner has two shot guns or even has an empty RPG in his inventory while requesting mine and he wonders why i dont trade it to him. This is my first time seeing this glitch so i thought it might be a hack. Thanks for your comment Hadeel ^^
