The Misterix Mod is a modification for GTA San Andreas. This mod contains many popular myths in GTA San Andreas such as Bigfoot, Leatherface, and Kifflom. It is infamous for being one of the first myth mods ever released, and many of the creatures featured within have been believed to be real and became myths of their own.
