Triggerbot
Fires automatically the moment your crosshair is on an enemy.
A triggerbot doesn't move your aim; it presses fire for you the instant your crosshair touches an enemy. You still aim yourself, which makes it look more natural than an aimbot.
A triggerbot with zero delay has a reaction time no human has. Add a small delay so the timing looks real. Fortnite Private includes a triggerbot.
