The Mummy Suit is a unique F1 spawnable full-body covering introduced during the Halloween Event in October of 2019. While somewhat similar in appearance, it should not be confused with the player-purchasable Mummy Wraps added one year later.
With defensive statistics identical in every way to the Wet Suit, this item can now only be spawned by administrators through the F1 console. It was primarily created to demonstrate the new skin texture of the existing scarecrow AI replacement, Mummies.
They are a favorite clothing type of devious RUST admins to terrify the uninitiated RUST community into an early grave.
