Postal 2

It is up to you which path you choose, the path of peace or the path of power, blood and gunpowder. The game can be easily classified as a 1st person 3D action shooter and the fact that it runs on the Unreal Warfare engine is one of its pros. Although it doesn't have a dazzling story, you will enjoy the variety of quests and hilarious quirks on which the authors built the game all the more.
