Postal III is the third installment in the popular Postal series of video games. This version uses Valve's Source Engine, a game engine that provides advanced graphic capabilities and improved physics for a superior gaming experience. Players take on the role of "The Postal Dude", an anti-hero who traverses surreal levels filled with outrageous characters to complete missions, solve puzzles, and generally cause chaos. The game features a number of mini-games as well as first person shooter (FPS) gameplay. With its focus on dark humor, extreme violence, and over-the-top action scenes, Postal III adds new depth to an already cult classic franchise.
