Catharsis Reborn

Catharsis Reborn is a total conversion mod for Postal III, serving as a free unofficial sequel to POSTAL 2 and its expansion, Apocalypse Weekend.
The mod overhauls the base game by fixing numerous bugs, and introduces a new story, maps, missions, weapons, and more, based on the original designs and early previews of Postal III from 2007-2009.
Like POSTAL 2, Catharsis Reborn features open-world gameplay that allows for free exploration.
