Sometimes causing mayhem gets a little old. After all, GTA Online only has so many weapons. Why stick with the normal rocket launcher or minigun when there is a mod that allows players to use a grappling hook gun? This mod lets a player use a grappling hook gun to swing across buildings, scale walls with ease, and even hijack police helicopters. That's right, with this mod, a player can grapple only a police helicopter and pull the cop-out while they take the wheel.
