All ranks of Intern including Shock Rocker Intern
The Shock Rocker Club is a weapon that was featured in the game manual for Munch's Oddysee, but was never actually used in the game. It is basically the Oddworld equivalent of a modern-day cattle prod or nightstick, and was intended to be used by both armored and unarmored variations of Interns. The club was not featured in the game due to time constraints, much like a number of other features cut from the game.
In Oddworld: Soulstorm, however, a variant of the Shock Rocker returned in the form of a baton now used by Shock Rocker Sligs.
