Postal 4: No Regerts is a first-person shooter video game developed by Running with Scissors, who were also responsible for the first two games in the Postal series, Postal and Postal 2. It was released on October 14, 2019, for Microsoft Windows through Steam's Early Access program, a decision which was made to acquire funding for the project and to involve the Postal community in the game's development process. Running with Scissors have described the game as the "true sequel" to Postal 2, contrasting it with Postal 2's unsuccessful 2011 sequel Postal III, which was panned by critics and players, as well as being "disowned" by Running with Scissors. The game is currently in the alpha stage of its development, and most of its planned features have yet to be implemented.
