Postal 4: No Regerts (sic) is a 2019 satirical first-person shooter developed and published by Running With Scissors. It is a direct sequel to Postal 2, ignoring the events of the critically and fan-panned Postal III.
Following the destruction of his hometown, the Postal Dude and his dog find themselves stranded in the town of Edensin, Arizona after their car is stolen. Much like Postal 2, the game is divided into several days, where players must complete errands and jobs daily in an attempt to get the Postal Dude's car back.
The following weapons appear in the video game Postal 4: No Regerts:
The Desert Eagle Mark XIX returns as the "Pistol" and functions similarly to its Postal 2 counterpart. It has a 7-round capacity, correct for the model in-game.
Introduced in the "The Cure" update, the SIG-Sauer P250 appears in-game as the "P350". It is one of the few weapons to not have appeared or have an equivalent in any previous Postal game.
The Smith & Wesson Model 629 Stealth Hunter appears in-game as the "Revolver" and functions not unlike its Postal 2: Paradise Lost counterpart. It has an incorrect 7-round cylinder.
A fictional quad-barreled shotgun known as "The Fournicator" was added in the "Dream of Scooter Fournication" update, and its model being updated in the "The Cure" update. It holds an appropriate 4 shells and has two firing modes: the first firing one barrel at a time, and the second firing all four barrels.
The AKM appears in-game as the "AK", and is the standard automatic weapon in the game. Its presence may be a reference to a CNN report on the original Postal, where a silhouette of an M16 was described as the "unmistakable image of an AK-47 rifle". It received a new model in the "Thursday" update.
The M16A4 was added in the "Tuesday" update and is referred to as the "M16". It has an incorrect 35-round capacity and has a higher rate of fire and more controllable recoil than the AKM, but has a seperate ammo type and deals less damage. Of note is that when it was first added, it had two front sights.
An M60E3 with a Mk 43 Mod 1 handguard is featured in the game, and is usable by the player unlike the M60 in Postal III. The M60E4 in-game contains RIS mounts similar those on the Mk 43 Mod 0/1 variant of the M60E4.
The Orion Flare Gun was added in the "Frames, flares and feet" update, and is known simply as the "Flare Gun". While the player is under effect of catnip, the Postal Dude will reload the flare gun by cramming a live flare through its muzzle.
