You don't need stealth because bots are deaf, and blind unless you are out in the open.
actually bots are state of the art experimental developed goverment technology only used at the highest of top secret forces for extremely complicated and classified tasks with the ability to but not limited to laser guided vision, aimbot, noclip, seeing you through walls, and a lot more. not to mention our top class technology has a stunning 26 senses, unlike the human which has 5 known senses. and how could we forget, they can respawn just as a player, change outfits to be camouflaged with surroundings, and they are the only bot ever in history known to show emotion.
