You cannot use throwing weapons with Dead Eye in multiplayer.
While you’re in Dead Eye mode, you are invincible.
You can only shoot one bullet at a time using Dead Eye Level 1[2] X Research source
You’ll still shoot at someone even if they try to take cover. It’s recommended that you mark targets near cover first, so that they have less time to get out of the way before getting shot.
Shooting a horse while someone’s riding it will take them out of the fight for a few moments. Shooting a gun out of someone’s hand will buy you time or spare their life, depending on the situation. Using Dead Eye Level 3 can make some of the hunting challenges much easier, especially when hunting birds.
