Postal 4: No Regerts[a] is a 2022 first-person shooter game developed and published by Running with Scissors. It was released on October 14, 2019, for Windows through Steam's Early Access program, a decision which was made to acquire public funding for the project and to involve the Postal community in the game's development process. Running with Scissors described the game as the "true sequel" to Postal 2, contrasting it with Postal 2's unsuccessful 2011 sequel Postal.
