Some players have nothing in their hands and just have their fists up like they are ready to punch you, but I can hear bullets coming from their hands and I am taking damage/bleeding from a weapon. The character just has their fists up like they are holding L2. This sometimes happens with friends as they tell me they have their gun/weapon out but I can see nothing in their hands but fists. Happens with all guns I have seen, can be difficult to trust players with invisible guns.
