The game is very story driven, and every level consists of a mission that begins with a cutscene and ends with one as well. Will the Dude follow the path of Good, joining the Catharsis police department to protect and serve? Or will he tap fresh new veins of crazy and find himself hunted and hounded by all? Level Design/Missions The typical initial screen of a mission Over the course of the game, he crosses paths with eco-zealots, 'Hockey Moms,' stereotypical gay Segway 'biker' gangs, deranged fast food mascots, corrupt government officials, Al Qaeda, the Venezuelan army, and even a meth-crazed rhino. Meanwhile, the Dude stumbles from one disastrous temp job to the next, just trying to make ends meet. Postal III is set against the backdrop of a satirically broken US economy where gas costs $17 a gallon and Mexico is forced to patrol its borders to prevent Americans from illegally jumping the fence looking for jobs and healthcare. Tasing hockey moms as a bodyguard of Jennifer Walcott Unfortunately, due to the global economic meltdown, left-wing 'green' extremism and hypocritical right-wing government corruption, life in Catharsis isn't much better. Following a brief prologue that recaps the events of Postal 2, the story follows the Postal Dude and his psychotic pit bull Champ as they emigrate to the town of Catharsis. Postal III follows Postal Dude Jr.'s failed one-day career in video game development (Postal 2) and the ensuing 'accidental' nuclear destruction of Paradise, Arizona ( Apocalypse Weekend). The game features appearances from low-tier celebrities such as film director Uwe Boll and porn star Ron Jeremy.

Unlike the previous game, Postal III is played from a third-person perspective and replaces that game's open world sandbox for a series of open-ended missions based along branching narrative paths. The game was developed using the Valve Source Engine. Postal III iterates upon the violent gameplay of Postal 2 in a new city called Catharsis.
