"Ten months later, on September 29, 2023, RWS was given limited access to the game store by the publisher of the now-bankrupt Akella, which later in October 13th 2023, the game was relisted on the Steam storefront with improvements such as fixed crashes, fixed multiple bugs, increased performance, and more due to the help of developers from Zoom, plus added Fart Gun to the game, which was initially a pre-order exclusive. As of today, Postal III is still receiving support on both Steam and Zoom Platform, and continued to be updated with new localization, bug fixes. The game soundtrack were later also made available on Steam in both MP3 and FLAC."
