Before Postal 2 would come out on Steam, Running With Scissors contacted a few mod makers to add some of their bug fixes, game modes and even weapons to the game. Some of the added content includes guns from Eternal Damnation: A Postal 2 Total Conversion that turned the base game into more into a horror game, and added the fan favorite mod A Week in Paradise. Running With Scissors would gradually hire five employees, including the developers of the aforementioned mods, who had a history with modding Postal games.
