The Electro Baton is a weapon that was used only in Grand Theft Auto 2 and never seen in any other GTA game. Its more or less a stun gun only in a form of a melee weapon. It shoots blind bullets and has no sound. If the bullet hits someone, an arc will be formed between the player and the person, but it has no effect in normal pedestrians, but the arc slows other players down in a multiplayer game.
Despite that this weapon was never used in the official levels of Grand Theft Auto 2, it can still be used by player-made level scripts.
