First you need to Become a hero/villain for the glitch to work (recommend being a hero)
ok your done with that now if your a hero become the Vanta hero (become the ninja if you are a villain) Then if you press shift you should be invisible then hold shift and crouch (press c) release the shift and press c again and your done!
this allows you to hold any weapon invisible but the weapons!! also don’t shoot, aim or shift because that will make you visible. the best weapon for this glitch is the knife, its black small hard to see and does 40 damage!!!So what you need to do is get a knife become invisible and then cut them into pieces. Oh and BTW if you’re playing with friends use your aura(the purple thing) to show your spot when you’re invisible.
